根据SwiftUI中的切换值更改文本

@State private var isSwitchedOn = false

Text(isSwitchedOn ? "开启" : "关闭")

Toggle(isOn: $isSwitchedOn) {
    Text("切换")
}

import SwiftUI

struct ContentView: View {
    @State private var isSwitchedOn = false
    
    var body: some View {
        VStack {
            Text(isSwitchedOn ? "开启" : "关闭")
                .font(.largeTitle)
            
            Toggle(isOn: $isSwitchedOn) {
                Text("切换")
            }
            .padding()
        }
    }
}

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