从一个视图过渡到另一个SwiftUI

struct ContentView: View {
    var body: some View {
        NavigationView {
            VStack {
                NavigationLink(destination: DetailView()) {
                    Text("Go to Detail")
                }
            }
        }
    }
}

struct DetailView: View {
    var body: some View {
        Text("Detail View")
    }
}

struct ContentView: View {
    @State private var showSheet = false
    
    var body: some View {
        VStack {
            Button(action: {
                self.showSheet = true
            }) {
                Text("Show Sheet")
            }
        }
        .sheet(isPresented: $showSheet) {
            DetailView()
        }
    }
}

struct DetailView: View {
    var body: some View {
        Text("Detail View")
    }
}

struct ContentView: View {
    var body: some View {
        TabView {
            Text("Tab 1")
                .tabItem {
                    Image(systemName: "1.circle")
                    Text("Tab 1")
                }
            
            Text("Tab 2")
                .tabItem {
                    Image(systemName: "2.circle")
                    Text("Tab 2")
                }
        }
    }
