swiftUI - 强制屏幕横向后无法关闭模式屏幕

Question

我打开一个完整的模态视图

.fullScreenCover(isPresented: self.$isPresentedPlayerView){
     NavigationLazyView((MainPlayerView(playerVM: PlayerVM(asset: self.mediaVM.asset), showModal: self.$isPresentedPlayerView)))
}

在playerView .onApper中我强制屏幕为横向模式 使用此代码:

   func forceLandscapeLeftPlayerView(){
       AppDelegate.orientationLock = UIInterfaceOrientationMask.landscape
       UIDevice.current.setValue(UIInterfaceOrientation.landscapeLeft.rawValue, forKey: "orientation")
       UINavigationController.attemptRotationToDeviceOrientation()
   }

当它尝试关闭 View 或将 isPresentedPlayerView 设置为 false 或通过presentationMode.wrappedValue.dismiss() 屏幕未关闭! 有什么想法吗？？？

这是关闭代码:

func closeView(){
    DispatchQueue.main.async {
        withAnimation{
            self.playerVM.pause()
            self.playerVM.destropyPlayer()
            AppDelegate.orientationLock = UIInterfaceOrientationMask.portrait
            UIDevice.current.setValue(UIInterfaceOrientation.portrait.rawValue, forKey: "orientation")
            UINavigationController.attemptRotationToDeviceOrientation()
            self.isPresentedPlayerView = false
        }
    }
}

顺便说一句，此代码在 Xcode 12.2 上工作，在 Xcode 12.3/.4 上停止工作

Answer 1

这段代码有效。我删除了 DispatchQueue、withAnimation 和前三行。也许，问题出在其他地方。

struct MainPlayerView: View {
    @Environment(\.presentationMode) var presentationMode
    
    
    var body: some View {
        NavigationView {
            Button(action: {
                self.resetOrientation()
                presentationMode.wrappedValue.dismiss()
            }, label: {
                Text("Click")
            })
        }
        .onAppear(perform: {
            UIDevice.current.setValue(UIInterfaceOrientation.landscapeLeft.rawValue, forKey: "orientation")
            UINavigationController.attemptRotationToDeviceOrientation()
        })
    }
    
    func resetOrientation() {
        UIDevice.current.setValue(UIInterfaceOrientation.portrait.rawValue, forKey: "orientation")
        UINavigationController.attemptRotationToDeviceOrientation()
    }
}
