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。
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。
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。

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];
}
