Afternoon All,
Im trying to make a view that contains a view within it.
Ie one button will take you to a given screen and produce a desired out put "path" , while the other button will take you into a loop with a given out put "Intensity" being either H,M,L.
I want to keep the chevron back button at the top of the screen on all views but it only conforms to Path.
below is an example of the code, I understand you can have two different stacks in the same view as the "parent / root will take priority" but don't know how to correct.
import SwiftUI
struct questionFour: View {
@StateObject private var appData = AppData()
init(){
UINavigationBar.setAnimationsEnabled(false)
}
var body: some View {
NavigationView {
EmptyBattery(appData: appData)
}
}
}
struct EmptyBattery : View {
@ObservedObject var appData: AppData
var body : some View {
BatteryTButton(B1Color: .clear, B2Color: .clear, B3Color: .clear, appData: appData)
}
}
struct RedBattery : View {
@ObservedObject var appData: AppData
var body : some View {
BatteryTButton(B1Color: .clear, B2Color: .clear, B3Color: .red, appData: appData)
}
}
struct OrangeBattery : View {
@ObservedObject var appData: AppData
var body : some View {
BatteryTButton(B1Color: .clear, B2Color: .orange, B3Color: .orange, appData: appData)
}
}
struct GreenBattery : View {
@ObservedObject var appData: AppData
var body: some View {
BatteryTButton(B1Color: .green, B2Color: .green, B3Color:.green, appData: appData)
}
}
struct questionFour_Previews: PreviewProvider {
static var previews: some View {
questionFour()
}
}
struct BatteryTButton : View {
var B1Color : Color
var B2Color : Color
var B3Color : Color
@ObservedObject var appData: AppData
@State private var isGreenBatteryActive = false
@State private var isOrangeBatteryActive = false
@State private var isRedBatteryActive = false
var body: some View {
ZStack {
VStack(spacing: 15) {
Text("Intensity?")
.font(.largeTitle)
Spacer()
Image("EmptyBattery")
Spacer()
NavigationLink(value: 11) {
Image("Tick")
.resizable()
.frame(width: 120,height:100)
}
}
.navigationDestination(for: Int.self) { value in
questionFive()
}
VStack(spacing: 15) {
Button(action: {
isGreenBatteryActive = true
appData.intensity = "H"
print("Your app intensity is:", appData.intensity)
}) {
Rectangle()
.fill(B1Color)
.frame(width: 200, height: 120)
.cornerRadius(20)
}
.fullScreenCover(isPresented: $isGreenBatteryActive) {
GreenBattery(appData: appData)
//.navigationBarBackButtonHidden(true)
}
Button(action: {
isOrangeBatteryActive = true
appData.intensity = "M"
print("Your app intensity is:", appData.intensity)
}) {
Rectangle()
.fill(B2Color)
.frame(width: 200, height: 120)
.cornerRadius(20)
}
.fullScreenCover(isPresented: $isOrangeBatteryActive) {
OrangeBattery(appData: appData)
//.navigationBarBackButtonHidden(true)
}
Button(action: {
isRedBatteryActive = true
appData.intensity = "L"
print("Your app intensity is:", appData.intensity)
}) {
Rectangle()
.fill(B3Color)
.frame(width: 200, height: 120)
.cornerRadius(20)
}
.fullScreenCover(isPresented: $isRedBatteryActive) {
RedBattery(appData: appData)
//.navigationBarBackButtonHidden(true)
}
}
.padding(.bottom, 30)
}
}
}

import SwiftUI
struct ContentView: View {
init() {
// Customize the UINavigationBar appearance
let appearance = UINavigationBarAppearance()
appearance.titleTextAttributes = [.font : UIFont.systemFont(ofSize: 35)] // Increase title font size
//appearance.largeTitleTextAttributes = [.font : UIFont.systemFont(ofSize: 35)] // Increase large title font size
UINavigationBar.appearance().standardAppearance = appearance
}
@EnvironmentObject var appData: AppData
var body: some View {
NavigationStack(path: $appData.path) {
HStack {
Spacer() // Push the title to the center
VStack {
NavigationLink(value: 1) {
Circle()
.frame(width: 100, height: 100)
}
NavigationLink(value: 2) {
Circle()
.frame(width: 100, height: 100)
}
NavigationLink(value: 3) {
Circle()
.frame(width: 100, height: 100)
}
}
.navigationDestination(for: Int.self) { value in
if value == 1 {
TestView1()
}
else {
Text("Selected box: \(value)")
}
}
Spacer() // Push the content to the right
}
.navigationBarTitle("Todo Lists", displayMode: .inline)
//this section updates "path as you click though the navigation,links"
.onReceive(appData.$path) { CurrentSelectionCode in
let path = CurrentSelectionCode
print("your path is:", path)
}
}
}

Hi all,
I am unsure as to why my print statements aren't being shown in the output section when I run a simulation ?
Please could you have a look at my code and explain ?
import SwiftUI
struct ContentView: View {
@State var dateIdentifier : String = ""
@State var lastSelectedIdentifier : String = ""
var body: some View {
NavigationView {
VStack {
Button(action: {
dateIdentifier.append("a");
lastSelectedIdentifier.append("a");
print(dateIdentifier);
}) {
NavigationLink(destination: Text("OutPut")) {
Rectangle()
.frame(width: 100, height: 100)
}
}
Button(action: {
dateIdentifier.append("b");
lastSelectedIdentifier.append("b");
print(dateIdentifier);
}) {
NavigationLink(destination: Text("OutPut")) {
Rectangle()
.frame(width: 100, height: 100)
}
}
Button(action: {
dateIdentifier.append("c");
lastSelectedIdentifier.append("c");
print(dateIdentifier);
}) {
NavigationLink(destination: Text("OutPut")) {
Rectangle()
.frame(width: 100, height: 100)
}
}
}
}
}
}
Thank you
Connor
