如何隐藏iOS状态栏

在我的iOS视频应用中，状态栏隐藏在一些视图控制器中。我已经使用以下代码做到了这一点。

[[UIApplication sharedApplication] setStatusBarHidden:YES];

它适用于iOS 5和iOS 6，但不适用于iOS 7。我在特定的视图控制器中尝试了这个，

Eg:

-(BOOL)prefersStatusBarHidden { return YES; }

它工作得很好，但是我不能在父视图控制器中再次显示状态栏。

试试这个简单的方法:

objective - c:

- (void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated]
    [[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationNone];
}

- (void)viewWillDisappear:(BOOL)animated
{
    [super viewWillDisappear:animated]
    [[UIApplication sharedApplication] setStatusBarHidden:NO withAnimation:UIStatusBarAnimationNone];
}

迅速:

override func viewWillAppear(animated: Bool) 
{
    super.viewWillAppear(animated)
    UIApplication.sharedApplication().setStatusBarHidden(true, withAnimation: UIStatusBarAnimation.None)
}

override func viewWillDisappear(animated: Bool) 
{
    super.viewWillDisappear(animated)
    UIApplication.sharedApplication().setStatusBarHidden(false, withAnimation: UIStatusBarAnimation.None)
}

在iOS7中隐藏状态栏:

打开你的plist-file，然后添加一个添加一行名为“基于视图控制器的状态栏外观”，并将其值设置为NO。

从UIKit > UIApplication.h:

// Setting statusBarHidden does nothing if your application is using the default UIViewController-based status bar system.
@property(nonatomic,getter=isStatusBarHidden) BOOL statusBarHidden;
- (void)setStatusBarHidden:(BOOL)hidden withAnimation:(UIStatusBarAnimation)animation NS_AVAILABLE_IOS(3_2);

所以应该将基于视图控制器的状态栏外观设置为NO

试试;

[[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationNone];

你应该将这个值添加到plist: "View controller-based status bar appearance"并将其设置为"NO"。
