状态栏隐藏

Storyboard

界面上选中UIViewController,最右边Simulated Metrics找到 Status Bar 设定成 None

ViewController

iOS 6通过[UIApplication sharedApplication] 取得app的单例，然后调用setStatusBarHidden方法隐藏 Status Bar。

iOS 7

Info.plist

不但要在Info.plist中增加 Status bar is initially hidden一行,选择为 YES,

还需增加 View controller-based status bar appearance 一行,选择为 NO。

- (void)viewDidLoad {
    [super viewDidLoad];
    
    [[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationSlide];
    
    // Do any additional setup after loading the view.
}

[[UIApplication sharedApplication] setStatusBarHidden:NO withAnimation:UIStatusBarAnimationSlide];
