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。

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;
    }

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。

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

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];
}

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];
}
