如何在单击按钮时以编程方式切换选项卡？在swiftui

import SwiftUI

struct ContentView: View {
    @State private var selectedTab = 0
    
    var body: some View {
        TabView(selection: $selectedTab) {
            Text("Tab 1")
                .tabItem {
                    Image(systemName: "1.circle")
                    Text("Tab 1")
                }
                .tag(0)
            
            Text("Tab 2")
                .tabItem {
                    Image(systemName: "2.circle")
                    Text("Tab 2")
                }
                .tag(1)
            
            Text("Tab 3")
                .tabItem {
                    Image(systemName: "3.circle")
                    Text("Tab 3")
                }
                .tag(2)
        }
        
        Button(action: {
            // 切换到下一个选项卡
            selectedTab = (selectedTab + 1) % 3
        }) {
            Text("切换选项卡")
                .padding()
                .background(Color.blue)
                .foregroundColor(.white)
                .cornerRadius(10)
        }
        .padding()
    }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}
