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。

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];
}

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=)

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。

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;
   }

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!

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。
