The answer here works tremendously but, as Im sure, is not ideal for everyone. Say ContentView2, in the link, is looping a list of NavigationLinks, when self.$isActive
is true, it triggers all the NavigationLinks to open so not ideal. I've found out about using tag and selection.
// Inside a ForEach loop
// Omitted is the use of EnvironmentObject
NavigationLink(
destination: DestinationView(id: loop.id),
tag: loop.id,
selection: self.$routerState.selection,
label: {
NavCell(loopData: loop)
}
)
.isDetailLink(false)
// State:
class RouterState: ObservableObject {
//@Published var rootActive: Bool = false
@Published var tag: Int = 0
@Published var selection: Int? = nil
}
How to pop the NavigationLink when inside of a loop? The answer in the link works but not inside a loop. Is there a way to amend the answer to use both tag and selection?
Using example from link above:
import SwiftUI
struct ContentView: View {
@State var isActive : Bool = false
var body: some View {
NavigationView {
List {
/// Data from the loop will be passed to ContentView2
ForEach(0..<10, id: \.self) { num in
NavigationLink(
destination: ContentView2(rootIsActive: self.$isActive),
isActive: self.$isActive
) {
Text("Going to destination \(num)")
}
.isDetailLink(false)
}
}
}
}
}
struct ContentView2: View {
@Binding var rootIsActive : Bool
var body: some View {
NavigationLink(destination: ContentView3(shouldPopToRootView: self.$rootIsActive)) {
Text("Hello, World #2!")
}
.isDetailLink(false)
.navigationBarTitle("Two")
}
}
struct ContentView3: View {
@Binding var shouldPopToRootView : Bool
var body: some View {
VStack {
Text("Hello, World #3!")
Button (action: { self.shouldPopToRootView = false } ){
Text("Pop to root")
}
}.navigationBarTitle("Three")
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView()
}
}
