iOS 基础学习（6）----隐藏状态栏（电池栏）

方法一：隐藏某个viewcontroller的状态栏：

- (void)viewDidLoad
{
[super viewDidLoad];

[self hiddenStatusBar];
// Do any additional setup after loading the view from its nib.
}
-(void)hiddenStatusBar
{
if ([self respondsToSelector:@selector(setNeedsStatusBarAppearanceUpdate)])
{
[self prefersStatusBarHidden];
[self performSelector:@selector(setNeedsStatusBarAppearanceUpdate)];
}
}
- (BOOL)prefersStatusBarHidden
{
return YES;
}

方法二；隐藏所有viewcontroller的状态栏：在plist里设置

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。
