如何导航到不同的视图？

Question

I am learning to use Swiftui and I need your help. The following pickers are present in my project:

    Picker(selection: $selectedChoose, label: Text("Cosa ti serve?")) {
            ForEach(0 ..< choose.count) {
            Text(self.choose[$0]).tag($0)
    }
    }.pickerStyle(SegmentedPickerStyle())
            //WheelPickerStyle



    Picker(selection: $selectedCountry, label: Text("Città")) {
            ForEach(0 ..< country.count) {
            Text(self.country[$0]).tag($0)
    }
    }

    Picker(selection: $selectedAppartamento, label: Text("Tipo appartamento")) {
            ForEach(0 ..< appartamento.count) {
            Text(self.appartamento[$0]).tag($0)
    }
    }

    Picker(selection: $selectedCamera, label: Text("Tipo camera")) {
            ForEach(0 ..< camera.count) {
            Text(self.camera[$0]).tag($0)
    }
    }

At the end of the View, I have the following Text to which I will add the NavigationLink:

Text("Mostra annunci")
.font(Font.custom("Helvetica Neue", size: 15))
.foregroundColor(.white)
.frame(width: 150, height: 30).foregroundColor(Color.white)
.background(Color(red: 0.649, green: 0.18, blue: 0.117)).cornerRadius(10).padding(15)

Is it possible to link user choices with different views? I mean, if a user selects a different city, room type and type of apartments, how can I link these choices to different views? Each view should show results based on the different choices made by the user in the pickers above. How can I do that?

Thank you in advance:)

Answer 1

you can popup new views using the.sheet(...). The restriction is that you can only have one of those. So you would have to do something like this:

        .sheet(isPresented: $showSheet) {
            if self.selectedCountry == "myCountry" {
                Text("myCountry")
            }
            else if self.selectedCountry == "yourCountry" {
                Text("yourCountry")
            }
            ... lots of other if else

In your case I would reconsider the whole structure. Use just one sheet option and pass in the choices the user made. And inside the new view present the data as chosen.
