在iOS 7中,UIStatusBar被设计成这样,它与视图合并:

(GUI由Tina tavvar设计)

It is cool, but it will somewhat mess up your view when you have something at the top part of your view, and it becomes overlapped with the status bar. Is there a simple solution (such as setting a property in info.plist) that can change the way it works [not overlapping] back to how it is in iOS6? I know a more straightforward solution is to have self.view.center.x + 20 points for every single view controller, but changing them will screw other dimensions up (having a different self.view.center.x can cause problem to custom segues, etc.) and suddenly it turns into a tedious job that is best to be avoided. I'll really be glad if someone can provide me an one-liner solution for this.

附注:我知道我可以隐藏状态栏

[[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationNone];

在didFinishLaunchingWithOptions方法中,但这是一个变通方法,一个避免问题的快捷方式,所以我不认为这是一个真正的解决方案。


你可以一起隐藏状态栏。所以你的应用会是全屏的。我想这是你能得到的最好的了。

UIStatusBarStyleNone或目标设置。


2013年9月19日更新: 固定缩放bug添加 self.window.bounds = CGRectMake(0,20, self.window.frame.size.width, self.window.frame.size.height); 纠正了NSNotificationCenter语句中的错别字

2013年9月12日更新: 修正了UIViewControllerBasedStatusBarAppearance为NO 增加了一个解决方案的应用程序与屏幕旋转 增加了一个改变状态栏背景颜色的方法。

显然,没有办法将iOS7的状态栏恢复到iOS6的工作状态。

然而,我们总是可以写一些代码,把状态栏变成像ios6一样,这是我能想到的最短的方法:

Set UIViewControllerBasedStatusBarAppearance to NO in info.plist (To opt out of having view controllers adjust the status bar style so that we can set the status bar style by using the UIApplicationstatusBarStyle method.) In AppDelegate's application:didFinishLaunchingWithOptions, call if (NSFoundationVersionNumber > NSFoundationVersionNumber_iOS_6_1) { [application setStatusBarStyle:UIStatusBarStyleLightContent]; self.window.clipsToBounds =YES; self.window.frame = CGRectMake(0,20,self.window.frame.size.width,self.window.frame.size.height-20); //Added on 19th Sep 2013 self.window.bounds = CGRectMake(0, 20, self.window.frame.size.width, self.window.frame.size.height); } return YES;

为了:

检查是否是iOS 7。 设置状态栏的内容为白色,而不是UIStatusBarStyleDefault。 避免那些超出可见边界的子视图出现(对于从顶部进入主视图的动画视图)。 通过移动和调整应用程序的窗口框架,创造一种状态栏占用空间的错觉,就像在iOS 6中一样。

对于具有屏幕旋转功能的应用程序,

使用NSNotificationCenter通过添加来检测方向变化

[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(applicationDidChangeStatusBarOrientation:)
name:UIApplicationDidChangeStatusBarOrientationNotification
object:nil];

在if (NSFoundationVersionNumber > NSFoundationVersionNumber_iOS_6_1),并在AppDelegate中创建一个新方法:

- (void)applicationDidChangeStatusBarOrientation:(NSNotification *)notification
{
    int a = [[notification.userInfo objectForKey: UIApplicationStatusBarOrientationUserInfoKey] intValue];
    int w = [[UIScreen mainScreen] bounds].size.width;
    int h = [[UIScreen mainScreen] bounds].size.height;
    switch(a){
        case 4:
            self.window.frame =  CGRectMake(0,20,w,h);
            break;
        case 3:
            self.window.frame =  CGRectMake(-20,0,w-20,h+20);
            break;
        case 2:
            self.window.frame =  CGRectMake(0,-20,w,h);
            break;
        case 1:
           self.window.frame =  CGRectMake(20,0,w-20,h+20);
    }
}

因此,当方向改变时,它将触发一个switch语句来检测应用程序的屏幕方向(纵向,倒置,横向左,或横向右),并分别改变应用程序的窗口框架,以创建iOS 6状态栏错觉。

更改状态栏的背景颜色:

Add

 @property (retain, nonatomic) UIWindow *background;

在AppDelegate.h中使背景成为类中的一个属性,并防止ARC释放它。(如果你不使用ARC,你不必这样做。)

之后,你只需要在if (NSFoundationVersionNumber > NSFoundationVersionNumber_iOS_6_1)中创建UIWindow:

background = [[UIWindow alloc] initWithFrame: CGRectMake(0, 0, self.window.frame.size.width, 20)];
background.backgroundColor =[UIColor redColor];
[background setHidden:NO];

别忘了@synthesize background;@implementation AppDelegate!


如果你不希望你的视图控制器被状态栏(和导航栏)重叠,在Xcode 5的Interface Builder中取消选中“在顶部栏下扩展边缘”框。


Interface Builder中有一个选项,调用iOS 6/7 Delta属性,旨在解决偏移问题。

在Stack Overflow的问题界面构建器:什么是UIView的布局iOS 6/7 delta ?


这是我写的一篇博客文章的交叉发布,但这里是关于iOS 7上的状态栏、导航栏和容器视图控制器的完整概述:

There is no way to preserve the iOS 6 style status bar layout. The status bar will always overlap your application on iOS 7 Do not confuse status bar appearance with status bar layout. The appearance (light or default) does not affect how the status bar is laid out (frame/height/overlap). It is important to note as well that the system status bar no longer has any background color. When the API refers to UIStatusBarStyleLightContent, they mean white text on a clear background. UIStatusBarStyleDefault is black text on a clear background. Status bar appearance is controlled along one of two mutually-exclusive basis paths: you can either set them programmatically in the traditional manner, or UIKit will update the appearance for you based on some new properties of UIViewController. The latter option is on by default. Check your app’s plist value for “ViewController-Based Status Bar Appearance” to see which one you’re using. If you set this value to YES, every top-level view controller in your app (other than a standard UIKit container view controller) needs to override preferredStatusBarStyle, returning either the default or the light style. If you edit the plist value to NO, then you can manage the status bar appearance using the familiar UIApplication methods. UINavigationController will alter the height of its UINavigationBar to either 44 points or 64 points, depending on a rather strange and undocumented set of constraints. If the UINavigationController detects that the top of its view’s frame is visually contiguous with its UIWindow’s top, then it draws its navigation bar with a height of 64 points. If its view’s top is not contiguous with the UIWindow’s top (even if off by only one point), then it draws its navigation bar in the “traditional” way with a height of 44 points. This logic is performed by UINavigationController even if it is several children down inside the view controller hierarchy of your application. There is no way to prevent this behavior. If you supply a custom navigation bar background image that is only 44 points (88 pixels) tall, and the UINavigationController’s view’s bounds matches the UIWindow’s bounds (as discussed in #4), the UINavigationController will draw your image in the frame (0,20,320,44), leaving 20 points of opaque black space above your custom image. This may confuse you into thinking you are a clever developer who bypassed rule #1, but you are mistaken. The navigation bar is still 64 points tall. Embedding a UINavigationController in a slide-to-reveal style view hierarchy makes this abundantly clear. Beware of the confusingly-named edgesForExtendedLayout property of UIViewController. Adjusting edgesForExtendedLayout does nothing in most cases. The only way UIKit uses this property is if you add a view controller to a UINavigationController, then the UINavigationController uses edgesForExtendedLayout to determine whether or not its child view controller should be visible underneath the navigation bar / status bar area. Setting edgesForExtendedLayout on the UINavigationController itself does nothing to alter whether or not the UINavigationController has a 44 or 64 point high navigation bar area. See #4 for that logic. Similar layout logic applies to the bottom of your view when using a toolbar or UITabBarController. If all you are trying to do is prevent your custom child view controller from underlapping the navigation bar when inside a UINavigationController, then set edgesForExtendedLayout to UIRectEdgeNone (or at least a mask that excludes UIRectEdgeTop). Set this value as early as possible in the life cycle of your view controller. UINavigationController and UITabBarController will also try to pad the contentInsets of table views and collection views in its subview hierarchy. It does this in a manner similar to the status bar logic from #4. There is a programmatic way of preventing this, by setting automaticallyAdjustsScrollViewInsets to NO for your table views and collection views (it defaults to YES). This posed some serious problems for Whisper and Riposte, since we use contentInset adjustments to control the layout of table views in response to toolbar and keyboard movements. To reiterate: there is no way to return to iOS 6 style status bar layout logic. In order to approximate this, you have to move all the view controllers of your app into a container view that is offset by 20 points from the top of the screen, leaving an intentionally black view behind the status bar to simulate the old appearance. This is the method we ended up using in Riposte and Whisper. Apple is pushing very hard to ensure that you don’t try to do #9. They want us to redesign all our apps to underlap the status bar. There are many cogent arguments, however, for both user experience and technical reasons, why this is not always a good idea. You should do what is best for your users and not simply follow the whimsy of the platform.


下面是广泛使用Storyboard的项目的另一种方法:

目标:

这种方法的目标是在iOS7中重新创建与在iOS6中相同的状态栏样式(见问题标题“iOS7状态栏回到iOS6样式?”)。

简介:

为了实现这一点,我们尽可能多地使用故事板,通过向下移动状态栏重叠的UI元素(在iOS 7下),同时使用增量来恢复iOS 6.1或更早版本的向下布局更改。在ios7中产生的额外空间然后被一个UIView占用,并将backgroundColor设置为我们选择的颜色。后者可以在代码中创建,也可以使用故事板(参见下面的替代方案)

假设:

为了在执行以下步骤时获得所需的结果,假设基于视图控制器的状态栏外观被设置为NO,并且您的状态栏样式被设置为“透明黑色样式(alpha of 0.5)”或“不透明黑色样式”。这两种设置都可以在项目设置的“信息”下找到或添加。

步骤:

Add a subview to the UIWindow to serve as your status bar background. To achieve this, add the following to your AppDelegate's application: didFinishLaunchingWithOptions: after makeKeyAndVisible if (NSFoundationVersionNumber > NSFoundationVersionNumber_iOS_6_1) { UIView *statusBarBackgroundView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, yourAppsUIWindow.frame.size.width, 20)]; statusBarBackgroundView.backgroundColor = [UIColor blackColor]; [yourAppsUIWindow addSubview:statusBarBackgroundView]; } Since you programmatically added a background for iOS 7 ONLY, you will have to adjust the layout of your UI elements that are overlapped by the status bar accordingly whilst preserving their layout for iOS6. To achieve this, do the following: Ensure that Use Autolayout is unchecked for your Storyboard (this is because otherwise "iOS 6/7 Deltas" is not shown in the Size Inspector). To do this: select your Storyboard file show Utilities select "Show the File Inspector" Under "Interface Builder Document" uncheck "Use Autolayout" Optionally, to help you monitor the layout changes for both iOS 7 AND 6 as you apply them, select the "Assistant Editor", select "Preview" and "iOS 6.1 or earlier": Now select the UI element you want to adjust so it isn't overlapped by the status bar anymore Select "Show the Size Inspector" in the Utilities column Reposition your UI element along the Y-axis by the same amount as the statusbar bg height: And change the iOS6/7 Deltas value for Y by the same NEGATIVE amount as the statusbar bg height (Note the change in the iOS 6 preview if you're using it):

选择:

为了在故事板繁重的项目中添加更少的代码,并让状态栏背景自动旋转,而不是以编程方式为状态栏添加背景,你可以为每个视图控制器添加一个彩色视图,位于所称视图控制器的主视图的最顶部。然后你将改变这个新视图的高度delta为与你的视图高度相同的负数(使它在iOS 6下消失)。

这个替代方案的缺点(尽管考虑到自旋转兼容性可能可以忽略不计)是,如果你在iOS 6中查看你的故事板,这个额外的视图不会立即可见。如果你看了一下故事板的“文档大纲”,你就会知道它在那里。


对于Archy Holt的回答,有一个小的选择,更简单一点:

a.在info.plist中设置“UIViewControllerBasedStatusBarAppearance”为“NO”

b.在AppDelegate的应用程序didFinishLaunchingWithOptions:中调用:

if ([[UIDevice currentDevice].systemVersion floatValue] < 7)
{
    self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
}
else
{
    // handling statusBar (iOS7)
    application.statusBarStyle = UIStatusBarStyleLightContent;
    self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].applicationFrame];
    self.window.clipsToBounds = YES;

    // handling screen rotations for statusBar (iOS7)
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(applicationDidChangeStatusBarOrientationNotification:) name:UIApplicationDidChangeStatusBarOrientationNotification object:nil];
}

并添加方法:

- (void)applicationDidChangeStatusBarOrientationNotification:(NSNotification *)notification
{
    // handling statusBar (iOS7)
    self.window.frame = [UIScreen mainScreen].applicationFrame;
}

你也可以考虑子类化UIWindow来处理UIApplicationDidChangeStatusBarOrientationNotification本身。


解决方案:

通过重写方法在你的视图控制器或rootviewcontroller中设置它:

-(BOOL) prefersStatusBarHidden
    {
        return YES;
    }

我非常简单的解决方案(假设你只支持垂直方向)是重新定义iOS版本7以下的应用程序窗口边界,在App委托didFinishLaunchingWithOptions方法中:

CGRect screenBounds = [[UIScreen mainScreen] bounds];
if ([HMService getIOSVersion] < 7) {
    // handling statusBar (iOS6) by leaving top 20px for statusbar.
    screenBounds.origin.y = 20;
    self.window = [[UIWindow alloc] initWithFrame:screenBounds];
}
else {
    self.window = [[UIWindow alloc] initWithFrame:screenBounds];
}

如果你正在使用接口构建器,试试这个:

在你的xib文件中:

1)选择主视图,设置背景颜色为黑色(或任何你想要状态栏的颜色)

2) Make sure the background is a self contained subview positioned as a top level child of the controller's view. Move your background to become a direct child of the controller's view. Check the autosizing panel to be sure that you've locked all frame edges, activated both flexibility axes, and if this is a UIImageView, set the content mode to Scale to fill. Programmatically this translates to contentMode set to UIViewContentModeScaleToFill and has its auto resizing mask set to (UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight).

3)现在将所有被锁定的东西上下移动20点,并设置iOS 6/7 delta Y为-20。 在自动缩放面板中,所有被锁定在顶部框架上的顶级子图层都需要向下移动20点,并将其iOS 6/7 delta Y设置为-20。(Cmd选择所有这些,并按下箭头20次-有更好的方法吗?)

4) Adjust the iOS 6/7 delta height of all of the above items that had a flexible height. Any of the items that were locked to the frame top and bottom and had flexible height enabled in the autosizing panel must also have their iOS 6/7 delta height set to 20. That includes the background view mentioned above. This may seem anti-intuitive, but due to the order in which these are applied, it is necessary. The frame height is set first (based on device), then the deltas are applied, and finally the autosizing masks are applied based upon the offset positions of all of the child frames - think it through for a bit, it will make sense.

5)最后,被锁定在底部框架而不是顶部框架的项目根本不需要delta。

这将给你在iOS7和iOS6中相同的状态栏。

另一方面,如果你想要iOS7样式同时保持iOS6兼容性,那么将背景视图的delta Y / delta height值设置为0。

更新(新解决方案) 本次更新是iOS 7导航栏问题的最佳解决方案。您可以设置导航栏颜色示例:FakeNavBar。backgroundColor = [UIColor redColor]; 注意:如果你使用默认的导航控制器,请使用旧的解决方案。 AppDelegate.m

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{

    if(NSFoundationVersionNumber >= NSFoundationVersionNumber_iOS_7_0)
    {
        UIView *FakeNavBar = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 20)];
        FakeNavBar.backgroundColor = [UIColor whiteColor];

        float navBarHeight = 20.0;
        for (UIView *subView in self.window.subviews) {

            if ([subView isKindOfClass:[UIScrollView class]]) {
                subView.frame = CGRectMake(subView.frame.origin.x, subView.frame.origin.y + navBarHeight, subView.frame.size.width, subView.frame.size.height - navBarHeight);
            } else {
                subView.frame = CGRectMake(subView.frame.origin.x, subView.frame.origin.y + navBarHeight, subView.frame.size.width, subView.frame.size.height);
            }
        }
        [self.window addSubview:FakeNavBar];
    }

    return YES;

}

旧的解决方案-如果你使用以前的代码,请忽略下面的代码和图像 这是旧版本的iOS 7导航栏解决方案。

我用以下代码解决了这个问题。这是用来添加状态栏的。 didFinishLaunchingWithOptions

if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7.0) {
    UIView *addStatusBar = [[UIView alloc] init];
    addStatusBar.frame = CGRectMake(0, 0, 320, 20);
    addStatusBar.backgroundColor = [UIColor colorWithRed:0.973 green:0.973 blue:0.973 alpha:1]; //change this to match your navigation bar
    [self.window.rootViewController.view addSubview:addStatusBar];
}

对于界面构建器,这是在iOS 6中打开的;它从0像素开始。

注意:iOS 6/7只有在详细信息窗格的“文件检查器”(最左边的图标)中取消视图控制器的“使用自动布局”时才会出现增量。


苹果发布了技术问答QA1797:防止状态栏覆盖你的视图。它适用于iOS 6和iOS 7版本。


我在iOS 7中实现了iOS 6的状态栏。

在info.plist中设置UIViewControllerBasedStatusBarAppearance为NO

(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions方法

if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7) {
    [application setStatusBarStyle:UIStatusBarStyleLightContent];
    self.window.clipsToBounds =YES;
    self.window.frame =  CGRectMake(0,20,self.window.frame.size.width,self.window.frame.size.height);

    //Added on 19th Sep 2013
    NSLog(@"%f",self.window.frame.size.height);
    self.window.bounds = CGRectMake(0,0, self.window.frame.size.width, self.window.frame.size.height);
}

它可能会把你所有的视图都压低20个像素。要克服这一点,请使用以下代码在-(void)viewDidAppear:(BOOL)animated方法

if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7) {
    CGRect frame=self.view.frame;
    if (frame.size.height==[[NSUserDefaults standardUserDefaults] floatForKey:@"windowHeight"])
    {
        frame.size.height-=20;
    }
    self.view.frame=frame;
}

你必须在didFinishLauncing Method中设置窗口分配后的windowHeight Userdefaults值

self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
[[NSUserDefaults standardUserDefaults] setFloat:self.window.frame.size.height forKey:@"windowHeight"];

我已经看了很多很多很多教程来解决这个该死的问题。但是没有一个有用!以下是我的解决方案,对我来说很管用:

if( [[[UIDevice currentDevice] systemVersion] floatValue] >= 7.0f ) {
    float statusBarHeight = [[UIApplication sharedApplication] statusBarFrame].size.height;
    for( UIView *v in [self.view subviews] ) {
        CGRect rect = v.frame;
        rect.origin.y += statusBarHeight;
        v.frame = rect;
    }
}

逻辑很简单。我改变了所有孩子对自我的看法。视图为20像素。 这是所有。然后,屏幕截图就会像iOS 6一样显示出来。我讨厌iOS7的状态栏!~ " ~


我的解决方案是在iOS 7上,在窗口顶部添加一个高度为20点的UIView。 然后我在AppDelegate类中创建了一个方法来显示/隐藏“固态”状态栏背景。在应用程序:didFinishLaunchingWithOptions::

// ...

// Add a status bar background
self.statusBarBackground = [[UIView alloc] initWithFrame:CGRectMake(0, 0, self.window.bounds.size.width, 20.0f)];
self.statusBarBackground.backgroundColor = [UIColor blackColor];
self.statusBarBackground.alpha = 0.0;
self.statusBarBackground.userInteractionEnabled = NO;
self.statusBarBackground.layer.zPosition = 999; // Position its layer over all other views
[self.window addSubview:self.statusBarBackground];

// ...
return YES;

然后我创建了一个方法来淡入/淡出黑色状态栏背景:

- (void) showSolidStatusBar:(BOOL) solidStatusBar
{
    [UIView animateWithDuration:0.3f animations:^{
        if(solidStatusBar)
        {
            [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];
            self.statusBarBackground.alpha = 1.0f;
        }
        else
        {
            [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleDefault];
            self.statusBarBackground.alpha = 0.0f;
        }
    }];
}

我现在要做的就是在需要时调用[appDelegate showSolidStatusBar:YES]。


最简单的方法就是在最新的Xcode上安装一个旧的SDK。

如何安装旧SDK到最新的Xcode?

你可以从http://www.4shared.com/zip/NlPgsxz6/iPhoneOS61sdk.html获取iOS 6.1 SDK,也可以下载旧的Xcode并从其内容中获取SDK 解压并粘贴到/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/ sdk 重新启动xcode。 你现在可以在项目的构建设置中选择一个旧的SDK

希望对你有所帮助。这对我有用=)


因为使用presentViewController:animated:completion:把window.rootViewController弄乱了。因此,我必须找到一个不同的方法来解决这个问题。我终于让它与模态和旋转工作通过子类化我的rootViewController的UIView。

.h

@interface RootView : UIView

@end

.m

@implementation RootView

-(void)setFrame:(CGRect)frame
{
    if (self.superview && self.superview != self.window)
    {
        frame = self.superview.bounds;
        frame.origin.y += 20.f;
        frame.size.height -= 20.f;
    }
    else
    {
        frame = [UIScreen mainScreen].applicationFrame;
    }

    [super setFrame:frame];
}

- (void)layoutSubviews
{
    self.frame = self.frame;

    [super layoutSubviews];
}

@end

现在你有了iOS7动画的强大解决方案。


我在所有的视图控制器中都使用了这个,很简单。 在你所有的viewDidLoad方法中添加这行:

- (void)viewDidLoad{
    //add this 2 lines:
    if ([self respondsToSelector:@selector(edgesForExtendedLayout)])
        self.edgesForExtendedLayout = UIRectEdgeNone;

    [super viewDidLoad];
}

隐藏状态栏的步骤:

1.转到您的应用程序信息。plist文件。

2.和设置,查看基于控制器的状态栏外观:布尔NO

希望我解决了状态栏问题.....


为了继续使用setStatusBarHidden:我使用这个类别:

@interface UIApplication (StatusBar)

-(void)setIOS7StatusBarHidden:(BOOL)statusBarHidden;

@end

@implementation UIApplication (StatusBar)

-(void)setIOS7StatusBarHidden:(BOOL)statusBarHidden{
    if (!IOS7) {
        [self setStatusBarHidden:statusBarHidden];
        return;
     }

    if ([self isStatusBarHidden] == statusBarHidden) {
        return;
    }

    [self setStatusBarHidden:statusBarHidden];
    [self keyWindow].clipsToBounds = YES;
    CGFloat offset = statusBarHidden ? 0 : 20;
    [self keyWindow].frame =  CGRectMake(0,offset,[self keyWindow].frame.size.width,[self keyWindow].frame.size.height-offset);
    [self keyWindow].bounds = CGRectMake(0, offset, [self keyWindow].frame.size.width,[self keyWindow].frame.size.height);
}

@end

我要迟到了,但我只是想分享我所做的,基本上 最简单的解决方案

首先->转到你的信息。plist文件并添加状态栏样式->透明黑色样式(Alpha 0.5)

现在,它开始了:-

在你的AppDelegate.m中添加这段代码

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
    {
     //Whatever your code goes here
  if(kDeviceiPad){

     //adding status bar for IOS7 ipad
         if (IS_IOS7) {
              UIView *addStatusBar = [[UIView alloc] init];
              addStatusBar.frame = CGRectMake(0, 0, 1024, 20);
              addStatusBar.backgroundColor = [UIColor colorWithRed:0 green:0 blue:0 alpha:1]; //change this to match your navigation bar
              [self.window.rootViewController.view addSubview:addStatusBar];
                    }
                }
    else{

         //adding status bar for IOS7 iphone
        if (IS_IOS7) {
            UIView *addStatusBar = [[UIView alloc] init];
            addStatusBar.frame = CGRectMake(0, 0, 320, 20);
            addStatusBar.backgroundColor = [UIColor colorWithRed:0 green:0 blue:0 alpha:1]; //You can give your own color pattern
            [self.window.rootViewController.view addSubview:addStatusBar];
        }

    return YES;
   }

我发现这里是这个导航栏问题在iOS7的最佳替代方案和解决方案!!

http://www.appcoda.com/customize-navigation-status-bar-ios-7/

我希望它能消除我们所有的疑问和担忧。


这可能是一个压倒性的问题,如果你使用自动布局,因为你不能直接操作帧。有一个简单的解决方案,不需要太多的工作。

我最终在一个实用工具类中编写了一个实用方法,并从所有视图控制器的viewDidLayoutSubviews方法中调用它。

+ (void)addStatusBarIfiOS7:(UIViewController *)vc
    {
        if (NSFoundationVersionNumber > NSFoundationVersionNumber_iOS_6_1) {
            CGRect viewFrame = vc.view.frame;
            if(viewFrame.origin.y == 20) {
                //If the view's y origin is already 20 then don't move it down.
                return;
            }
            viewFrame.origin.y+=20.0;
            viewFrame.size.height-= 20.0;
            vc.view.frame = viewFrame;
            [vc.view layoutIfNeeded];
        }
    }

重写视图控制器中的viewDidLayoutSubviews方法,在那里你想要状态栏。它会让你通过自动布局的负担。

- (void)viewDidLayoutSubviews
{
    [[UIApplication sharedApplication]setStatusBarStyle:UIStatusBarStyleLightContent];
    [super viewDidLayoutSubviews];
    [MyUtilityClass addStatusBarIfiOS7:self];
}

试试这个简单的方法....

步骤1:在单个viewController中更改

[[UIApplication sharedApplication] setStatusBarStyle: UIStatusBarStyleBlackOpaque];

步骤2:更改整个应用程序

info.plist
      ----> Status Bar Style
                  --->UIStatusBarStyle to UIStatusBarStyleBlackOpaque

第三步:在每个viewWillAppear中添加这个来调整iOS7的状态栏高度

    [[UIApplication sharedApplication]setStatusBarStyle:UIStatusBarStyleLightContent];
    if ([[UIDevice currentDevice].systemVersion floatValue] >= 7) {
        CGRect frame = [UIScreen mainScreen].bounds;
        frame.origin.y+=20.0;
        frame.size.height-= 20.0;
        self.view.frame = frame;
        [self.view layoutIfNeeded];
    }

这可能太晚了,但我有一些东西可以贡献,这可能会帮助到某人,我试图子类化UINavigationBar,并想让它看起来像ios 6黑色状态栏和白色状态栏文本。

以下是我发现的方法

        self.navigationController?.navigationBar.clipsToBounds = true
        self.navigationController?.navigationBar.translucent = false
        self.navigationController?.navigationBar.barStyle = .Black
        self.navigationController?.navigationBar.barTintColor = UIColor.whiteColor()

它使我的状态栏背景为黑色,状态栏文本为白色,导航栏为白色。

iOS 9.3, XCode 7.3.1
