swiftui - swiftUI - 强制屏幕到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，我使用以下代码强制屏幕进入横向模式：

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

并且当它尝试关闭视图或将 isPresentedPlayerView 设置为 false 或通过 presentationMode.wrappedValue.dismiss() 屏幕未关闭时！任何想法？？？

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，此代码适用于 Xcode 12.2 并停止适用于 xcode 12.3/ .4

Answer 1

此代码有效。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()
    }
}
