关于statebar的隐藏和显示的问题

- (void)viewDidLoad { [[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationSlide];
[super viewDidLoad];
一定要放在[super
viewDidLoad]这个前面，
离开当前页面的时候把statebar的状态给成可见的状态
-
(void)viewWillDisappear:(BOOL)animated{ [[UIApplication sharedApplication] setStatusBarHidden:NO withAnimation:UIStatusBarAnimationSlide];
设置颜色
[[UINavigationBar appearance] setBarTintColor:[UIColor yellowColor]];
