如何在SwiftUI中更改NavigationView的目标？

struct ContentView: View {
    var body: some View {
        NavigationView {
            // 内容视图
        }
    }
}

struct ContentView: View {
    var body: some View {
        NavigationView {
            VStack {
                NavigationLink(destination: Text("目标视图1")) {
                    Text("链接1")
                }
                
                NavigationLink(destination: Text("目标视图2")) {
                    Text("链接2")
                }
            }
        }
    }
}

struct ContentView: View {
    @State private var showDestination1 = false
    @State private var showDestination2 = false
    
    var body: some View {
        NavigationView {
            VStack {
                NavigationLink(destination: Text("目标视图1"), isActive: $showDestination1) {
                    Text("链接1")
                }
                
                NavigationLink(destination: Text("目标视图2"), isActive: $showDestination2) {
                    Text("链接2")
                }
            }
        }
    }
}

Button(action: {
    self.showDestination1 = true
}) {
    Text("更改目标视图1")
}
