IOS 开发状态栏隐藏的实现办法

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions  
{  
  [application setStatusBarHidden:YES];  
  return YES;  
}  
 

- (BOOL)prefersStatusBarHidden NS_AVAILABLE_IOS(7_0); // Defaults to NO  
[objc] view plaincopyprint? 
- (BOOL)prefersStatusBarHidden  
{  
  // iOS7后,[[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationFade];  
  // 已经不起作用了  
  return YES;  
}
