SwiftUI onTapGesture 仅调用一次

[英]SwiftUI onTapGesture called only once

我正在开发这个带有多个视图组件的音频播放器。 当我们单击中间视图中的任意位置时,我添加了一种隐藏/显示顶视图和底视图的方法。

在它工作正常之前,但最近当我再次尝试时,它只会关闭它并且不会再次触发onTapGesture

我相信与之前的唯一区别是视图是呈现而不是推送到视图 controller 中。

我尝试在TapGesture() onEnded()自定义手势,但结果相同。 我还尝试添加一个 Rectangle 形状,如 [here][1] 所述。

struct PlayerView: View {
    @ObservedObject private var playerState = PlayerState()
    @Binding var isPlayerReduced: Bool

    private let interfaceColor: Color = .gray//.black
    private let interfaceOpacity: Double = 0.9
    private let interfaceAnimationDuration: Double = 0.4

    var body: some View {
        ZStack(content: {
            GeometryReader(content: { geometry in
                VStack(content: {
                    if !self.playerState.isInterfaceHidden {
                        TopPlayerView(playerState: self.playerState,
                                      isPlayerReduced: self.$isPlayerReduced)
                            .transition(.opacity)
                            .background(self.interfaceColor.opacity(self.interfaceOpacity))
                    }
                    MiddlePlayerView(skipIntro: self.$playerState.skipIntro)
                        // Allow to spread the background zone for click purposes
                        .background(Color.clear)
                        // I want to have the middle under my TopPlayer and my BottomPlayer
                        .zIndex(-1)
                        .onTapGesture(perform: {
                            withAnimation(.easeInOut(duration: self.interfaceAnimationDuration)) {
                                self.playerState.isInterfaceHidden.toggle()
                            }
                        })
                    //                            .gesture(TapGesture()
                    //                                .onEnded({ _ in
                    //                                }))
                    if !self.playerState.isInterfaceHidden {
                        BottomPlayerView(playerState: self.playerState)
                            .padding(.bottom, geometry.safeAreaInsets.bottom)
                            .transition(.opacity)
                            .background(self.interfaceColor.opacity(self.interfaceOpacity))
                    }
                })
            })
        })
            .background(Color.black)
            .edgesIgnoringSafeArea(.all)
            .navigationBarTitle("")
            .navigationBarHidden(true)
    }
}

我在这里有点想法,欢迎任何帮助! 谢谢你!

好的,所以在触及这段代码中的所有可能之后。 我最终使它工作。 不同之处在于我将填充放在我的视图中。 我将填充物切换到VStack而不是我在VStack中的视图。 它现在似乎起作用了。

我在工作代码下面发布。

var body: some View {
        ZStack(alignment: .center, content: {
            GeometryReader(content: { geometry in
                VStack(content: {
                    self.topMarker()
                    if !self.playerState.isInterfaceHidden {
                        TopPlayerView(playerState: self.playerState,
                                      isPlayerReduced: self.$isPlayerReduced)
                            .transition(.opacity)
                            .background(self.interfaceColor.opacity(self.interfaceOpacity))
                    }
                    MiddlePlayerView(skipIntro: self.$playerState.skipIntro)
                        // Allow to spread the background zone for click purposes
                        .background(Color.white.opacity(0.00000001))
                        // I want to have the middle under my TopPlayer and my BottomPlayer
                        .zIndex(-1)
                        .onTapGesture(perform: {
                            withAnimation(.easeInOut(duration: self.interfaceAnimationDuration)) {
                                self.playerState.isInterfaceHidden.toggle()
                            }
                        })
                    if !self.playerState.isInterfaceHidden {
                        BottomPlayerView(playerState: self.playerState)
                            .transition(.opacity)
                            .background(self.interfaceColor.opacity(self.interfaceOpacity))
                    }
                })
                    .padding(.top, 8)
                    .padding(.bottom, geometry.safeAreaInsets.bottom)
            })
        })
            .background(Color.black)
            .edgesIgnoringSafeArea(.all)
            .navigationBarTitle("")
            .navigationBarHidden(true)
    }

老实说,我不知道这里有什么区别......即使在视图调试器中也没有区别......
