ios - 在 Swiftui 中如何通过旋转到横向自动关闭模态

Question

我目前使用基于此代码的景观环境对象 - https://stackoverflow.com/a/58503841/412154
在我看来，我的模态使用@State/@Binding 适本地出现和消失，具体取决于“完成”按钮按下。我的应用程序在旋转到横向时确实显示了不同的 View ，我希望模式在旋转时自动关闭，但无法弄清楚如何根据另一个 @ennvironmentobject 更改 @binding var
这是我的模态视图的简化示例

struct StepsView: View {
    @Binding var isPresented:Bool
    @EnvironmentObject var orientation:Orientation

    var body: some View {
        VStack(alignment: .center) {
              Text("Step")
              }
             .navigationBarItems(trailing: Button(action: {
                    //print("Dismissing steps view...")
                    self.isPresented = false
                }) {
                    Text("Done").bold()
                })
            }

谢谢你的帮助!

欣赏@davidev的回答，但我希望每个模态的行为都有点不同，所以我这样做了

struct StepsView: View {
    @Binding var isPresented:Bool
    @EnvironmentObject var orientation:Orientation
    
    private var PortraitView:some View {
        VStack(alignment: .center) {
              Text("Modal")
              }
             .navigationBarItems(trailing: Button(action: {
                    self.isPresented = false
                }) {
                    Text("Done").bold()
                })
            }
    
    
    var body: some View {
        buildView(isLandscape: orientation.isLandScape, isShowing: &isPresented)
    }

    func buildView(isLandscape:Bool, isShowing:inout Bool) -> AnyView {

        if !isLandscape {
            return AnyView(PortraitView)
        } else {
            isShowing = false
            return AnyView(EmptyView())
        }
    }
