IOS下隐藏电池等statusBar

用IOS 7.0运行以前的代码，擦，那屏幕上面的是神马，电池电量显示，好恶心，干掉吧。在RootViewController下添加以下代码:

- (void)viewDidLoad{    [super viewDidLoad];        // 设置IOS7不显示电池等statusBar    if ([self respondsToSelector:@selector(setNeedsStatusBarAppearanceUpdate)])    {        // iOS 7        [self prefersStatusBarHidden];        [self performSelector:@selector(setNeedsStatusBarAppearanceUpdate)];    }}/** * 返回YES隐藏电池等statusBar */- (BOOL)prefersStatusBarHidden{    return YES;}

OK,搞定了~！

还有个方法，设置info.plist

首先设置key：Status bar is initially hidden    为YES

然后设置key：View controller-based status bar appearance  为NO

即可实现全局隐藏状态栏了
