I want to hide the navigationbarTitle for my views, but keep a custom value for the back button in the child views. So the NavigationBar should be visible in every screen, but should not have a title. But i want to change the text 'Back' to a custom text.
NavigationLink {
SomeChildView()
} label: {
SomeView()
}.navigationBarTitle("Text for back button in child view")
If I set the title on the NavigationLink this gives me my custom back button text but also displays the title in the Parent View.
You can achieve what you need by using the environment value of presentationMode to dismiss the screen you are in by code, and for changing the back button label and style you can simply do
hide the back button by using .navigationBarBackButtonHidden(true) modifier
use toolbar and toolbarItem to add your custom back button to the NavigationBar
here an example of how you can use it
// FirstScreen
struct ContentView: View {
var body: some View {
NavigationView {
NavigationLink {
SecondScreen()
} label: {
Text("Go To Second Screen")
}
}
}
}
// SecondScreen
struct SecondScreen: View {
#Environment(\.presentationMode) var presentationMode
var body: some View {
Text("Second Screen")
.navigationBarBackButtonHidden(true)
.toolbar {
ToolbarItem(placement: .navigationBarLeading) {
Button {
presentationMode.wrappedValue.dismiss()
} label: {
Label("Custom Back Button", systemImage: "command")
.labelStyle(.titleAndIcon)
}
}
}
}
}

I am navigating from one screen to another on previous screen i am hiding navigation bar but on second screen I want to show navigation bar but in mu case its hiding on second screen also.
navigation bar hidden on first screen as
.navigationBarHidden(true)
How can i show navigation bar on second screen? (I am NOT using navigation view on either screen)
My First parent screen has
NavigationView {
//design
}
.navigationBarTitle("ABCScreen", displayMode: .inline)
.navigationViewStyle(StackNavigationViewStyle())
Thank you for help.
The possible approach to hide navigation bar in root view and show in child subviews.
struct FirstNavigationView: View {
#State private var hideBar = true // << hide state
var body: some View {
NavigationView {
VStack {
Text("FirstView")
Divider()
NavigationLink("Goto Child", destination: NextChildView(index: 1))
.simultaneousGesture(TapGesture().onEnded {
self.hideBar = false // << show
})
}
.navigationBarHidden(hideBar)
// .navigationBarTitle("Back to Root") // << choice
.onAppear {
self.hideBar = true // << hide on back
}
}
}
}
The only needed modifications is in root view.
For your first screen you can add .navigationBarHidden(true) inside your NavigationView to hide it and false on second screen to unhide.
FIRST SCREEN:
NavigationView{
Button(action: {}, label: {
Text("Button")
})
.navigationBarHidden(true) //This flag will hide your navigationBar
}
SECOND SCREEN:
NavigationView{
Button(action: {}, label: {
Text("Button")
})
.navigationBarHidden(false) //This flag will unhide your navigationBar
}
I have two views, one leads to the other. I want that the second view uses the title of the first view for the back button, which should then be: "<View1".
I don't want to show the title in the first view.
Problem: I can't hide navigation bar because it will also hide a custom button which is within it. Setting .navigationTitle("") hides the title in the first view, but also hides it from the back button in the second view.
What I have now:
What I would like to have:
Code:
struct ContentView: View {
#State var isLinkActive = false
var body: some View {
NavigationView {
VStack {
NavigationLink("go to the second view", destination: SecondView(), isActive: $isLinkActive).navigationTitle("View1")
.navigationBarItems(leading: Button(action: {
()
}, label: {
Text("custom button")
}))
}
}.navigationViewStyle(StackNavigationViewStyle())
}
private func btnPressed() {
isLinkActive = true
}
}
struct SecondView: View {
var body: some View {
Color.blue
}
}
You need to create custom back button for destination view as well,and you shouldn’t set navigation title for navigationLink, that’s why you are not able to hide “View1” correctly.
Check below code.
import SwiftUI
struct Test: View {
#State var isLinkActive = false
var body: some View {
NavigationView {
VStack {
NavigationLink("go to the second view", destination: SecondView()
.navigationBarBackButtonHidden(true)
.navigationBarItems(leading: Button(action: {
isLinkActive = false
}, label: {
HStack{
Image(systemName: "backward.frame.fill")
Text("View1")
}
})) ,
isActive: $isLinkActive)
}.navigationBarItems(leading: Button(action: {
()
}, label: {
Text("custom button")
}))
}.navigationViewStyle(StackNavigationViewStyle())
}
private func btnPressed() {
isLinkActive = true
}
}
struct SecondView: View {
var body: some View {
Color.blue
}
}
You can try and make navigationBar code as reusable component, because you might need to do this at multiple places.
Output-:
I achieved this by using two modifiers on my main view. Similar to your case, I didn't want a title on the first view, but I wanted the back button on the pushed view to read < Home, not < Back.
.navigationTitle("Home")
.toolbar {
ToolbarItem(placement: .principal) {
Text("")
}
}
I have two views. View1 has a NavigationLink which leads to View2.
However the "Back" Button to get back to View1 only says "Back" and not the title of View1.
How can I change the Buttons Text without creating a button via NavigationBarItems?
Adding a Button via NavigationBarItems removes the animation when the second view shows up.
struct View1: View {
var body: some View {
NavigationView {
List {
Text("ExampleText1")
Text("ExampleText2")
}
.navigationBarTitle("View1")
.navigationBarItems(
trailing:
NavigationLink(destination: View2()) {
Image(systemName: "plus.circle").font(.system(size: 25))
})
}
}
}
struct View2: View {
var body: some View {
List {
Text("Example")
Text("Example")
}
.navigationBarTitle("View2")
}
}
Solution:
"View1" was too long.
I use a NavigationLink to navigate from "View1" to "View2", on the second view, the back button gets the title of the previous view
But, if the title of the previous view is very long, then the back button gets the text "Back"
How could I change that "Back" text?
I wanna make my app available in multiple languages, but it seems that "Back" does not change when phone's language changes
struct ContentView: View {
var body: some View {
return NavigationView {
VStack {
Text("View1")
NavigationLink(destination: Text("View2").navigationBarTitle("Title View2", displayMode: .inline)) {
Text("NavigationLink")
}
}.navigationBarTitle("Title View1")
}
}
}
PS: I'd like to keep this functionality as it it, I just want to change the language used for back button
here is a workaround ....
struct ContentView: View {
#State private var isActive: Bool = false
var body: some View {
NavigationView {
VStack {
NavigationLink(destination: DetailView(), isActive: $isActive) {
Text("Title View2")
}
}.navigationBarTitle(! isActive ? "Title View2" : "Your desired back Title", displayMode: .inline)
}
}
}
struct DetailView: View {
var body: some View {
Text("View2")
}
}
I found a solution which can work also very good.
View1 set a toolbar item with .principal and add your Text or what you want.
for example :
ToolbarItem(placement: .principal) {
HStack{
Text("View1")
}.font(.subheadline)
}
and set also your title in View1:
.navigationTitle("Back")
And do nothing in your view2. it will automatically add your view1 title to your view2 default back button text
I've managed to localize back buttons by providing translations for the Back key in the Localizable.strings file.
I am using SwiftUI though.
You can create a custom back button in your navigation link by hiding native navigationBackButton. In the custom back button, you can add your translated custom back button title.
struct ContentView: View {
var body: some View {
return NavigationView {
VStack {
Text("View1")
NavigationLink("NavigationLink", destination: NextView())
}.navigationBarTitle("Title View1")
}
}
}
struct NextView: View {
#Environment(\.presentationMode) var presentationMode: Binding<PresentationMode>
var backButton : some View { Button(action: {
self.presentationMode.wrappedValue.dismiss()
}) {
HStack {
Image("backImage") // BackButton Image
.aspectRatio(contentMode: .fit)
.foregroundColor(.white)
Text("Go Back") //translated Back button title
}
}
}
var body: some View {
VStack {
Text("View2")
}
.navigationBarTitle("Title View2",displayMode: .inline)
.navigationBarBackButtonHidden(true)
.navigationBarItems(leading: backButton)
}
}
Output:-
Create your own button, then assign it using .navigationBarItems(). I found the following format most nearly approximated the default back button.
#Environment(\.presentationMode) var presentationMode: Binding<PresentationMode>
var backButton : some View {
Button(action: {
self.presentationMode.wrappedValue.dismiss()
}) {
HStack(spacing: 0) {
Image(systemName: "chevron.left")
.font(.title2)
Text("Cancel")
}
}
}
Make sure you use .navigationBarBackButtonHidden(true) to hide the default button and replace it with your own!
List(series, id:\.self, selection: $selection) { series in
Text(series.SeriesLabel)
}
.navigationBarBackButtonHidden(true)
.navigationBarItems(leading: backButton)
Add localization to your project. If language was set with user device settings(or simulator), after you add localization to your project it will work. Project's supported language must match with selected one on device.
It seems as though I'm unable to choose which pages I want to hide the Navigation Bar on in swift UI.
I have the following screens:
Main
struct Main: View {
var body: some View {
NavigationView {
Home()
}
}
}
Home
struct Home: View {
var body: some View {
NavigationLink(destination: Details()) {
Text("Go Next")
}
// I expect the navigation bar to show up here, and it does
.navigationBarTitle("Home")
.navigationBarHidden(false)
}
}
Details
struct Details: View {
#Environment(\.presentationMode) var mode: Binding<PresentationMode>
var body: some View {
Button(action: { self.mode.wrappedValue.dismiss() }) {
Text("Go Back")
}
// I expect the navigation bar to be hidden here
// At first, it is hidden. Then, after a second, it pops up
// with the title "Details"
.navigationBarTitle("Details")
.navigationBarHidden(true)
}
}
Either I'm doing this wrong (likely), or Apple has some work to do (also likely).
As I saw earlier, something comes wrong, when you use both:
.navigationBarTitle("some text")
.navigationBarHidden(true)
in code below there is no navigation bar staff and nothing pops up:
struct Details: View {
#Environment(\.presentationMode) var mode: Binding<PresentationMode>
var body: some View {
Button(action: { self.mode.wrappedValue.dismiss() }) {
Text("Go Back")
}
.navigationBarHidden(true)
.navigationBarBackButtonHidden(true) // even no back button
}
}
