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。
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;
}
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];
}
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"];
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。
