【问题描述】：

倒计时结束后，我想跳转到另一个视图。 我试过navigationLink，但没有用。

这是我的代码。

struct TimerView: View 

    @State var timeRemaining = 5

    let timer = Timer.publish(every: 1, on: .main, in: .common).autoconnect()

    var body: some View 
        Text("\(timeRemaining)")
            .font(.largeTitle)
            .onReceive(timer)  _ in
                if self.timeRemaining > 0 
                    self.timeRemaining -= 1

                
            
    

【参考方案1】：

尝试一些变体：

struct TimerView: View 
    @State var timeRemaining = 5
    @State var jump = false
    
    let timer = Timer.publish(every: 1, on: .main, in: .common).autoconnect()
    
    var body: some View 
        NavigationView 
            VStack 
                Text("\(timeRemaining)")
                    .font(.largeTitle)
                    .onReceive(timer)  _ in
                        if timeRemaining > 0 
                            timeRemaining -= 1
                         else 
                            jump = true
                            // optional stop the timer
                            timer.upstream.connect().cancel()
                        
                    
                NavigationLink("", destination: Text("the other view"), isActive: $jump)
