  对于每个视图控制器，您想要更改状态栏的可见性，您需要覆盖 prefersStatusBarHidden . 为了实际工作，您必须在项目的_2654599中添加以下键/值：

  Key: View controller-based status bar appearance

  Value: YES

  ---

  要控制 viewWillAppear 和 viewWillDisappear 中状态栏的可见性，您可以执行以下操作：

  var statusBarHidden = false
  
  override func viewWillAppear() {
      super.viewWillAppear()
      statusBarHidden = false
      self.setNeedsStatusBarAppearanceUpdate()
  }
  
  override func viewWillDisappear() {
      super.viewWillDisappear()
      statusBarHidden = true
      self.setNeedsStatusBarAppearanceUpdate()
  }
  
  override var prefersStatusBarHidden: Bool {
      return statusBarHidden
  }

  对于Swift 3，

  override var prefersStatusBarHidden: Bool{
          return true
      }
  

  并添加 viewDidLoad()

  self.modalPresentationCapturesStatusBarAppearance = true

  为Objective-C编写示例（与@dennykim编写的SWIFT相同的代码）

  • 为BOOL创建属性

  @property（nonatomic，assign）BOOL statusBarHidden;

  • 在info.plist中设置 View controller-based status bar appearance == YES

  • 转到ViewController并编写下一个代码：

  • （无效）viewWillAppear中：（BOOL）动画{

  [super viewWillAppear:animated];
  
  self.statusBarHidden = TRUE;
  [self setNeedsStatusBarAppearanceUpdate];
  }
  -(void)viewWillDisappear:(BOOL)animated{
      [super viewWillDisappear:animated];
  
      self.statusBarHidden = FALSE;
      [self setNeedsStatusBarAppearanceUpdate];   
  }
  
  - (BOOL)prefersStatusBarHidden {
      return self.statusBarHidden;
  }
