SwiftUI条件视图转换不起作用

Question

考虑以下代码：

                     Source 1        |        Source 2         |      Source 3
          |  Next Day; Ground; 2 Day | Next Day; Ground; 2 Day | Next Day; Ground; 2 Day 
+Manager 1| 
   Rep 1  |
   Rep 2  |
+Manager 2|
   Rep 1  |
   Rep 2  |

问题

在这种情况下，我看到从IntroView到LoginView的过渡工作正常，除了任何动画。基于条件的IntroView内部动画效果似乎不错，但更改整个屏幕的过渡效果似乎无效。

Answer 1

1. 将group更改为ZStack

2. 在某处添加动画。

               class ApplicationHostingViewModel: ObservableObject {
                     @Published var value: Bool = false
                   }
   
                   struct ApplicationHostingView: View {
                     // view model env obj
                       @ObservedObject var applicationHostingViewModel : ApplicationHostingViewModel
                     var body: some View {
                       ZStack {
   
                         if applicationHostingViewModel.value {
                           LoginView()
                             .transition(.move(edge: .leading))
                         } else {
                           IntroView(applicationHostingViewModel:applicationHostingViewModel)
                         }
                       }
                     }
                   }
   
                   struct IntroView: View {
                     // view model env obj
                        @ObservedObject var applicationHostingViewModel : ApplicationHostingViewModel
                     var body: some View {
                       Button(action: {
                           withAnimation(.default){
                               self.applicationHostingViewModel.value = true} }) {
                         Text("Continue")
                       }
                     }
                   }
   
                   struct LoginView: View {
                     var body: some View {
                       Text("Hello World").frame(maxWidth: .infinity, maxHeight:  .infinity)
                     }
                   }
