如何在SwiftUI中从警报打开视图? 它必须具有2个按钮,一个打开视图A,另一个打开视图B。 我试图创建一个自定义视图,但是当我单击NavigationLink按钮转到另一个视图并返回时,仍会出现警报。 这是代码:
import SwiftUI
struct AlertTemperature: View {
@Binding var activeMessage: Bool
@State var activeYes: Bool = false
@State var activeNo: Bool = false
@ObservedObject var viewRouter : ViewRouter
var body: some View {
VStack{
Text("¿Desea tomar la temperatura?")
.padding(.bottom,20)
HStack{
NavigationLink(destination: QuickTempView(viewRouter: self.viewRouter), isActive: $activeYes){
Button(action: {
//print("Di clic en si")
self.activeYes.toggle()
self.activeMessage.toggle()
}){
HStack{
Spacer()
Text("Si")
.padding(.all,10)
Spacer()
}
}
.background(Color("DarkBlue"))
.foregroundColor(.white)
}.padding(.bottom,20)
.padding(.leading,20)
.padding(.trailing,10)
NavigationLink(destination: PreConfirmView(viewRouter: self.viewRouter), isActive: $activeNo){
Button(action: {
//print("Di clic en no")
self.activeMessage = false
self.activeNo.toggle()
}){
HStack{
Spacer()
Text("No")
.padding(.all,10)
Spacer()
}
}
.background(Color("DarkBlue"))
.foregroundColor(.white)
}.padding(.bottom,20)
.padding(.leading,10)
.padding(.trailing,20)
}
}.padding(20)
.background(Color.white)
.cornerRadius(15)
}
}
