Currently I am working on SwiftUI project. I want to hide the build-in navbar. For this purpose I have to add these lines,
.navigationBarBackButtonHidden(true)
.navigationBarHidden(true)
to each of view before pushing it into navigation controller in SwiftUI.
NavigationLink(destination:
ForgotPasswordView()
.navigationBarBackButtonHidden(true)
.navigationBarHidden(true)
) {
Text("Forgot Password?")
.foregroundColor(.white)
}
Same will be done for LoginView
NavigationLink(destination:
LoginView()
.navigationBarBackButtonHidden(true)
.navigationBarHidden(true)
) {
Text("Login")
.foregroundColor(.white)
}
So I need any generic method like we did in storyboard, hide it from root view and no child will have the navbar on top.

You can wrap the view by creating a new view that accepts a child view, which adds all the necessary modifiers so that you don't have to repeat it every time.
struct NavigationWrapper<Content: View>: View {
#ViewBuilder var childView: Content
var body: some View {
childView
.toolbar(.hidden)
}
}
Now, you can use that wrapper for your navigation link's destination.
Here is an example:
struct ContentView: View {
var body: some View {
NavigationStack {
List {
ForEach(0..<10) { i in
NavigationLink("Row \(i)") {
NavigationWrapper {
Text("Detailed view for \(i)th row.")
}
}
}
}
.navigationTitle("RowGap")
.toolbar(.hidden)
}
}
}
It hides out the navigation bar and toolbar completely.

I want to have a TabView inside a NavigationView. The reason is that I am showing a List inside the TabView. When a user taps on an item in the list, the list uses a NavigationLink to show a detailed screen.
The problem is that the navigationBarTitle is now broken. It does not animate when the user scrolls through the items (sometimes). I don't want to wrap my NavigationView inside the TabView, since that will always show the TabView. I don't want it.
This is the reproduction code. If you run this in the simulator, the animation will break when switch a few times between the tabs and you scroll through the list. You will see that the navigation bar will remain where it is, without the animation.
import SwiftUI
struct ContentView: View {
var body: some View {
NavigationView {
TabView {
TestView()
.tabItem {
Image(systemName: "person.3")
}
TestView()
.tabItem {
Image(systemName: "person.2")
}
}
.navigationTitle("Test")
.navigationViewStyle(.stack)
}
}
}
struct TestView: View {
var body: some View {
List {
Text("test")
}
.listStyle(.plain)
}
}
I have a NavigationView and added a title. The problem is it looks weird when I run it.
var body: some View {
NavigationView {
Form {
Section {
Text("Hello World")
}
}
.navigationBarTitle("SwiftUI", displayMode: .inline)
}
}
The image looks weird. How can I make the navigation height look better just like UIKIt Navigation Bar
You have a double-nested NavigationView.
The view that you are showing in your example is already being presented from a NavigationView, so you don't need to create an additional view.
This is because the navigation view context is preserved when you use a NavigationLink.
Try removing it:
var body: some View {
Form {
Section {
Text("Hello World")
}
}
.navigationBarTitle("SwiftUI", displayMode: .inline)
}
I'm just picking up SwiftUI after a long break but I don't understand why I can't place a Navigation View within a Tab View.
I want my Navigation View to be a .tabItem so the view appears as part of the main app navigation so I'm trying this :
struct ContentView: View {
var body: some View {
TabView {
NavigationView {
.tabItem {
Text("Home")
}
Text("Tab bar test")
.navigationBarTitle("Page One")
}
}
This doesn't work with error message
Cannot infer contextual base in reference to member 'tabItem'
But when I try this
var body: some View {
TabView {
NavigationView {
Text("Tab bar test")
.navigationBarTitle("Page One")
}
}
.tabItem {
Image(systemName: "1.circle")
Text("Home")
}
}
It builds fine but the tab bar doesn't show up.
My primary question which I'm hoping would be useful to others, is ...
Why can't I make a make a Navigation View a tab bar item by nesting .tabItem directly inside the Navigation View (as per my first example)?
I think it's a similar question to this one but there's no code there. And then quite similar to this one but they seem to be using .tabItem directy with ContentView like I want to with NavigationView but that isn't building!?
I'm probably misunderstanding something simple but I don't get this at all at the moment.
Do this for a better overview:
ContentView:
struct ContentView : View {
var body: some View {
TabView {
FirstView()
.tabItem {
Image(systemName: "folder.fill")
Text("Home")
}
SecondView()
.tabItem {
Image(systemName: "folder.fill")
Text("SecondView")
}
}
}
}
FirstView
struct FirstView: View {
var body: some View {
NavigationView {
Text("FirstView")
.navigationBarTitle("Home")
}
}
}
}
SecondView
struct SecondView: View {
var body: some View {
NavigationView {
Text("SecondView")
.navigationBarTitle("Home")
}
}
}
}
.tabItem should be used as a modifier on the view that represents that tab.
In the first example, this doesn't work because of a syntax error -- you're trying to use it on the opening of a closure in NavigationView {, when instead you want it on the outside of the closing brace: NavigationView { }.tabItem(...)
In the second example, you're using .tabItem as a modifier on the entire TabView instead of the NavigationView.
Both of your examples may have revealed what was going on more obviously if you indent your code so that you can see the hierarchy. Trying selecting your code in Xcode and using Ctrl-I to get Xcode to properly format it for you.
Here's a working version:
struct ContentView : View {
var body: some View {
TabView {
NavigationView {
Text("Tab bar test")
.navigationBarTitle("Page One")
}
.tabItem { //note how this is modifying `NavigationView`
Image(systemName: "1.circle")
Text("Home")
}
}
}
}
I have an Issue where my text disappears behind the navigation bar. The navigation bar is made visible once the user clicks on Settings (or any other menu button). It shows up and the content is visible but then when done loading the new view the text disappears behind the bar. Any solutions?
I change the status of the navigation bar being visible with .onAppear and .onDisappear of views that are root level.
Code something like this:
struct ContentView: View {
#State public var navBarHidden = true
var body: some View {
NavigationView{
VStack{
ZStack(alignment: .center){
WhiteImage().onAppear{self.navBarHidden = true} //Here only seen as white background
BottomButtons().onDisappear{self.navBarHidden = false}
ProfileInvoke().navigationBarTitle("").navigationBarHidden(self.navBarHidden)
}
}
}
}
}
//The buttons are done with such a construct
struct MenuButton: View {
var buttonText: String
var buttonCallView: AnyView
var body: some View {
NavigationLink(destination: self.buttonCallView) {
Text(self.buttonText)
}.padding()
}
}
//Population of a button
MenuButton(buttonText: "My Favourites", buttonCallView: AnyView(MyFavouritesView().navigationBarTitle(Text("My Favourites"), displayMode: .inline)))
// The settings view where the title disappears
struct SettingsView: View {
var body: some View {
HStack(alignment: .top){
VStack(alignment: .leading){
Text("General").bold()
Divider()
Spacer()
}.padding()
Spacer()
}
}
}
I have the feeling that it has something to do with the .onAppear and .onDisappear where I set the status of the navigation bar being hidden or not. Ain't sure tho.
I am having trouble with navigation in SwiftUI. I have a button on a navigation bar, if clicked it pushes a new navigation view with list of items. When one of those items is tapped, it pushes a detail view.
But I am ending up with something like this.
Below is the code
struct FirstView: View {
var body: some View {
NavigationView {
List {
...
}
.navigationBarTitle(Text("First View"))
.navigationBarItems(trailing: MyButton())
}
}
}
struct MyButton: View {
var body: some View {
NavigationLink("SecondView", destination: SecondView())
}
}
struct SecondView: View {
var body: some View {
NavigationView {
Text("My View")
}
}
}
Remove the NavigationView from SecondView.
The NavigationLink puts the second view inside the first views navigations view, so you do not need to put it inside a second one.
You can still update the title of the view from SecondView like so:
struct SecondView: View {
var body: some View {
Text("My View")
.navigationBarTitle("Second View")
}
}
Quinn is right.
but if You don't want a big area above:
add:
struct SecondView: View {
var body: some View {
Text("My View")
.navigationBarTitle("Second View", displayMode: .inline)
}
}
