如何在SwiftUI中退出付款？

struct PaymentView: View {
    @Environment(\.presentationMode) var presentationMode
    
    var body: some View {
        VStack {
            // 付款所需的输入字段和按钮
            Text("Payment View")
            Button("Cancel") {
                cancelPayment()
            }
        }
    }
    
    func cancelPayment() {
        // 执行取消付款的操作
        presentationMode.wrappedValue.dismiss() // 返回到之前的页面或关闭当前视图
    }
}

struct ContentView: View {
    var body: some View {
        NavigationView {
            // 主视图或其他导航视图
            NavigationLink(destination: PaymentView()) {
                Text("Go to Payment")
            }
        }
    }
}
