ios - 通话中状态栏将 View 推出底部

Question

我正在用 swift 编写一个 iOS 应用程序。

我有一个动态启动屏幕，然后是登录页面。

我使用本教程来替换框架: iOS: Root Controller Navigation

class RootViewController: UIViewController {
   ...
   override func viewDidLoad() {
      super.viewDidLoad()

      addChildViewController(current)               // 1
      current.view.frame = view.bounds              // 2             
      view.addSubview(current.view)                 // 3
      current.didMove(toParentViewController: self) // 4
   }
}

func showLoginScreen() {

      let new = UINavigationController(rootViewController: LoginViewController())                               // 1
      addChildViewController(new)                    // 2
      new.view.frame = view.bounds                   // 3
      view.addSubview(new.view)                      // 4
      new.didMove(toParentViewController: self)      // 5
      current.willMove(toParentViewController: nil)  // 6
      current.view.removeFromSuperview()]            // 7
      current.removeFromParentViewController()       // 8
      current = new                                  // 9
   }
}

但问题是它不遵守通话状态栏。如果在打开应用程序之前打开通话状态栏，我的 View 将从底部显示在屏幕之外。

在您的AppDelegate中使用它:

func application(_ application: UIApplication, willChangeStatusBarFrame newStatusBarFrame: CGRect) {
    UIView.animate(withDuration: 0.35, animations: {() -> Void in
        var windowFrame: CGRect? = (self.window?.rootViewController as? UINavigationController)?.view?.frame
        if newStatusBarFrame.size.height > 20 {
            windowFrame?.origin.y = newStatusBarFrame.size.height - 20
            // old status bar frame is 20
        }
        else {
            windowFrame?.origin.y = 0.0
        }
        (self.window?.rootViewController as? UINavigationController)?.view?.frame = windowFrame!
    })
}
