支持 Landscape Orientation 的 UiViewController 将其他 View 置于 Landscape

Question

我现在搜索了一天，没有找到合适的解决方案。我的应用程序由一个 Tab Bar Controller 和一个 Navigation Controllers 组成。我希望所有屏幕都只有纵向，但只有一个子视图是横向。

它可以到达那里，但是当我从子视图 return 物理上保持横向时，parent 也显示为横向，尽管我只允许 .portrait找到控制器。

我已经做了：

extension UITabBarController {
   override open var shouldAutorotate: Bool {
      get {
          if let visibleVC = selectedViewController {
              return visibleVC.shouldAutorotate
          }
          return super.shouldAutorotate
      }
   }

   override open var preferredInterfaceOrientationForPresentation: UIInterfaceOrientation{
       get {
           if let visibleVC = selectedViewController {
               return visibleVC.preferredInterfaceOrientationForPresentation
           }
           return super.preferredInterfaceOrientationForPresentation
       }
   }

   override open var supportedInterfaceOrientations: UIInterfaceOrientationMask {
      // your custom logic for rotation of selected tab
         get {
               if let visibleVC = selectedViewController {
                   return visibleVC.supportedInterfaceOrientations
               }
               return super.supportedInterfaceOrientations
           }
   }
}

extension UINavigationController {
   override open var shouldAutorotate: Bool {
       get {
           if let visibleVC = visibleViewController {
               return visibleVC.shouldAutorotate
           }
           return super.shouldAutorotate
       }
   }

   override open var preferredInterfaceOrientationForPresentation: UIInterfaceOrientation{
       get {
           if let visibleVC = visibleViewController {
               return visibleVC.preferredInterfaceOrientationForPresentation
           }
           return super.preferredInterfaceOrientationForPresentation
       }
   }

   override open var supportedInterfaceOrientations: UIInterfaceOrientationMask{
       get {
           if let visibleVC = visibleViewController {
               return visibleVC.supportedInterfaceOrientations
           }
           return super.supportedInterfaceOrientations
       }
   }
}

并在 parent 控制器中：

  override var shouldAutorotate: Bool{
      return true
   }

   override var preferredInterfaceOrientationForPresentation: UIInterfaceOrientation{
        return .portrait
   }

   override var supportedInterfaceOrientations: UIInterfaceOrientationMask{
      return .portrait
   }

当我将设备转到纵向时，视图再次以纵向显示，但我希望在取消横向 child 后立即发生这种情况，即使我不转动设备也是如此.

有什么想法吗？谢谢！

在您的横向视图控制器中添加此代码

override func viewDidLoad() {
    super.viewDidLoad()
let appDelegate = UIApplication.shared.delegate as! AppDelegate
    appDelegate.myOrientation = .landscapeRight
}

和 ViewWillDisappear 添加这个

override func viewWillDisappear(_ animated: Bool) {
    let appDelegate = UIApplication.shared.delegate as! AppDelegate
    appDelegate.myOrientation = .portrait
    UIView.setAnimationsEnabled(false)
    UIDevice.current.setValue(UIInterfaceOrientation.portrait.rawValue, forKey: "orientation")
    UIView.setAnimationsEnabled(true)
    UIViewController.attemptRotationToDeviceOrientation()
    UIView.setAnimationsEnabled(false)
}

在 appDeledate 中添加这一行

var window: UIWindow?
var myOrientation: UIInterfaceOrientationMask = .portrait
