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。
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

[self keyWindow].bounds = CGRectMake(0, offset, [self keyWindow].frame.size.width,[self keyWindow].frame.size.height);
}
@end
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。
