I have a TabView with 2 tabs in it, each tab containing a NavigationView. I need to hide the TabBar when navigating to another view. One solution would be to place the TabView inside of one NavigationView, but I have to set different properties for each NavigationView.
TabView(selection: $selectedTab, content: {
NavigationView {
VStack {
NavigationLink(destination: Text("SecondView Tab1")) {
Text("Click")
}
}
}.tabItem {
Text("ONE")
}.tag(0)
NavigationView {
VStack {
NavigationLink(destination: Text("SecondView Tab2")) {
Text("Click")
}
}
}.tabItem {
Text("TWO")
}.tag(1)
})
P.S. I am using Xcode 11 Beta 5
A little late but it will work, put your NavigationView before the TabView and the tab buttons are going to be hidden when you use a navigation link in your tabbed views.
NavigationView{
TabView{
...
}
}
I have same problem for this;
And I did the following actions to solve this problem:
Use NavigationView Contain a TabView And Hidden the NavigationBar
Make a Custom NavigaitonView like this
In next view Still hidden NavigationBar
// root tab
NavigationView {
TabView {
// some
}
.navigationBarTitle(xxx, displayMode: .inline)
.navigationBarHidden(true)
}
// custom navigation view
#available(iOS 13.0.0, *)
struct MyNavigationView: View {
var body: some View {
HStack {
Spacer()
Text(some)
Spacer()
}
.frame(height: 44)
}
}
// this view
VStack {
MyNavigationView()
Image(some)
.resizable()
.frame(width: 100, height: 100, alignment: .top)
.padding(.top, 30)
Spacer()
HStack {
ClockView()
Spacer()
NavigationLink(
destination: DynamicList(),
label: {
Image(some)
}).navigationBarHidden(true)
}
.padding(EdgeInsets(top: 0, leading: 15, bottom: 0, trailing: 15))
Spacer()
}
// next view
var body: some View {
VStack {
List {
MyNavigationView()
ForEach(date, id: \.self) { model in
Text(model)
}
}
.navigationBarHidden(true)
.navigationBarTitle(some, displayMode: .inline)
}
}
You can't hide the tab bar as far as I know if you navigation view its listed as a child, your tab bar contains your navigation view.

I have 2 screens, one with a NavigationView to make a navigation bar, and one with a TabView. In the TabView, I added a bar button item icon for each tab using ToolbarItem inside a new NavigationView, but when I run my app, the icon shows up in the middle of the navigation bar, instead of at the top.
What do I change to make the bar button items appear at the top of a navigation bar?
First screen:
struct ContentView: View {
init() {
UINavigationBar.appearance().backgroundColor = UIColor(Color(.systemGreen))
}
var body: some View {
NavigationView {
VStack(alignment: .leading, spacing: 30) {
NavigationLink(destination: HomeView()) {
Text("Go to tabs screen")
}
}.padding(20)
}
}
}
Second screen:
struct HomeView: View {
var body: some View {
TabView {
NavigationView {
VStack(alignment: .leading) {
Text("Tab 1")
.padding(.leading, 30)
}
.toolbar {
ToolbarItem {
Button(action: {
print("person icon pressed")
}, label: {
Image(systemName: "person.crop.circle").imageScale(.large)
}
)
}
}
}.tabItem {
Image(systemName: "list.bullet")
.font(.system(size: 26))
Text("Tab 1")
}
NavigationView {
VStack(alignment: .leading) {
Text("Tab 2")
}
.toolbar {
ToolbarItem {
Button(action: {
print("Plus icon pressed.")
}, label: {
Image(systemName: "plus").imageScale(.large)
}
)
}
}
}.tabItem {
Image(systemName: "books.vertical")
.font(.system(size: 26))
Text("Tab 2")
}
}
}
}
This is what they look like in iPhone 11 simulator:
But I want the icons to be at the top like they're shown in Preview:
I'm a beginner at swiftui. I need to add an exit button to .navigationBarItems. How can I add this button in the parent NavigationView to show this button on all children's views?
// a simple example on my question
struct FirstView: View {
var body: some View {
NavigationView {
ZStack{
TabView{
SubExampleViewOne()
.tabItem {
Image(systemName: "house.fill")
Text("Home")
}
SubExampleViewTwo()
.tabItem {
Image(systemName: "bookmark.circle.fill")
Text("Bookmark")
}
}
}
//here I have added a toolbar and it is perfectly visible in tabitem
//this is what I am trying to achieve, the visibility of the button on all pages
.toolbar {
ToolbarItem(placement: .navigationBarTrailing) {
ButtonExitView()
}
}
}
}
}
something strange - if I add NavigationLink in this way, Image and Text("Home") are visible twice
and the ToolbarItem is no longer on the new page
struct SubExampleViewOne: View {
var body: some View {
Text("This is hime page!")
.padding()
NavigationLink(destination: SubExampleViewThree()){
Text("Navigation link")
}
}
}
struct SubExampleViewTwo: View {
var body: some View {
Text("Hello, world!")
.padding()
}
}
struct SubExampleViewThree: View {
var body: some View {
Text("This is Navigation link")
.padding()
}
}
struct ButtonExitView: View {
var body: some View {
Button(action: {}, label: {Image(systemName: "arrowshape.turn.up.right.circle")})
}
}
after learning about TabView, I thought that there should be a similar solution for the top of the page
You have to add the button to each child view separately.
And you should use .toolbar and .toolBarItem because .navigationBarItems is deprecated.
I want to change views once the user taps 'get started' but due to having navigation view in my first view, it is showing back button on my next screen which I don't want. Please see the images attached below.
Code for the first view is below:
import SwiftUI
struct ContentView: View {
var body: some View {
NavigationView {
VStack {
Spacer()
Text("LifePath")
.font(.system(size: 48, weight: .semibold))
.padding(.bottom)
Spacer()
NavigationLink(destination: ViewChanger()) {
Text("Get Started")
.font(.headline)
.navigationBarBackButtonHidden(true)
}
}
.padding()
}
}
}
back button showing on screen 2
First view
Change the location of your navigationBackButtonHidden modifier so that it actually modifies the view that you're going to (and not the NavigationLink label):
struct ContentView: View {
var body: some View {
NavigationView {
VStack {
Spacer()
Text("LifePath")
.font(.system(size: 48, weight: .semibold))
.padding(.bottom)
Spacer()
NavigationLink(destination: ViewChanger()
.navigationBarBackButtonHidden(true) // <-- Here
) {
Text("Get Started")
.font(.headline)
}
}
.padding()
}
}
}
If you want not only the back button to be gone, but the entire header bar, you can use the .navigationBarHidden(true) modifier.
Also, if you run this on iPad at all, you probably want .navigationViewStyle(StackNavigationViewStyle()) added to the outside of your NavigationView
If you use a NavigationLink (in a NavigationView), the view will be pushed. If you want to replace the view, you can do this with an if statement.
For example, this could be implemented like this:
struct ContentView: View {
#State var showSecondView: Bool = false
var body: some View {
if !showSecondView {
NavigationView {
VStack {
Spacer()
Text("LifePath")
.font(.system(size: 48, weight: .semibold))
.padding(.bottom)
Spacer()
Button(action: { showSecondView = true }) {
Text("Get Started")
.font(.headline)
}
}
.padding()
} else {
TabView {
// ...
}
}
}
}
In my SwiftUI app, I would like to bring the navigation bar items down like in Apple's own UIKit apps.
Seen below is a screenshot from the Health app. Notice how the profile picture is in line with the 'Summary' text. This is what I am looking to achieve.
I have tried using .padding(.top, 90) but this has not worked as it does not bring down the virtual box that allows the button to be clicked. Using padding means that you have to tap the button above the image/text.
Thank you.
Unfortunately I didn't find any solution for changing navigation bar height in iOS 13 with SwiftUI, and had the same issues earlier. Solution below will fit you, if your navigation bar is always only black and you're ok with gap on the top:
struct NavBarCustomItems: View {
init() {
setNavigationBarToBlackOnly()
}
func setNavigationBarToBlackOnly() {
let blackAppearance = UINavigationBarAppearance()
blackAppearance.configureWithOpaqueBackground()
blackAppearance.backgroundColor = .black
blackAppearance.shadowColor = .clear // to avoid border line
UINavigationBar.appearance().standardAppearance = blackAppearance
UINavigationBar.appearance().scrollEdgeAppearance = blackAppearance
}
var body: some View {
NavigationView {
VStack {
NavigationBarMimicry()
// here is your content
HStack {
Text("Favorites")
Spacer()
Button(action: {}) { Text("Edit") }
}
.padding()
Spacer()
VStack {
Text("Main screen")
}
// you need spacer(s) to be sure, that NavigationBarMimicry is always on the top
Spacer()
}
}
}
}
// MARK: here is what you need in navigation bar
struct NavigationBarMimicry: View {
var body: some View {
HStack {
Text("Summary")
.bold()
.font(.system(size: 40))
.foregroundColor(.white)
.padding(.horizontal)
Spacer()
Rectangle()
.foregroundColor(.white)
.frame(width: 40)
.padding(.horizontal)
}
.background(Color.black)
.frame(height: 40)
.navigationBarTitle("", displayMode: .inline)
// you can add it to hide navigation bar, navigation will work via NavigationLink
// .navigationBarHidden(true)
}
}
struct NavBarCustomItems_Previews: PreviewProvider {
static var previews: some View {
NavBarCustomItems().environment(\.colorScheme, .dark)
}
}
the result should be like this:
P.S. maybe the other ways are:
Put views in this order: VStack { NavigationBarMimicry(); NavigationView {...}};
uncomment line of code: .navigationBarHidden(true);
I'm trying to figure out how to use the navigation bar in SwiftUI
I want to put BarButtonItem and images inside the NavigationBar
I have been able to display the navigation bar and put titles
var body: some View {
NavigationView{
List(0...5) { note in
VStack(alignment: .leading) {
Text("title")
Text("Date")
.font(.subheadline)
.foregroundColor(.secondary)
}
}
.navigationBarTitle(Text("Notes"))
}
}
iOS 14
You should use the toolbar modifier:
.toolbar {
ToolbarItem(placement: .navigationBarLeading) {
Button("Cancel") { /* action */ }
}
ToolbarItem(placement: .navigationBarTrailing) {
Button(action: { /* Actions */ }, label: {
HStack {
Image(systemName: "trash")
Text("Delete")
}
})
.foregroundColor(.red) // You can apply colors and other modifiers too
}
}
Note 1: You can have ANY View there. (not only a Button) and also any modifiers
Note 2: Both codes above and below will generate the same look items but with different approachs
iOS 13 and above (deprecated but still works)
You should use .navigationBarItems() modifier. For example you can add Button or Image like this:
.navigationBarItems(
leading: Button("Cancel") {
// Actions
},
trailing: Button(action: {
// Actions
}, label: { Label("Delete", systemImage: "trash") }
).foregroundColor(.red) // You can apply colors and other modifiers too
)
💡 Pro TIP
Always try to encapsulate each item in a separated struct, so your code will be simplified and very easy to replace with newer technologies. for example, take a look at this sample:
.navigationBarItems(
leading: MyCustomButtonItem(),
trailing: MyCustomButtonItem(text: "foo", image: "Bard")
)
.navigationBarItems() is the function you are looking for. You can specify a leading view, trailing view, or both. Within the view, you can specify horizontal and vertical stacks to add additional buttons.
var body: some View {
NavigationView{
List(0...5) { note in
VStack(alignment: .leading) {
Text("title")
Text("Date")
.font(.subheadline)
.foregroundColor(.secondary)
}
}
.navigationBarItems(leading: HStack {
Button(action: {}, label: {Image(systemName: "star.fill")})
Button(action: {}, label: {Text("Edit")})
}, trailing: VStack {
Button(action: {}, label: {Image(systemName: "star.fill")})
Button(action: {}, label: {Text("Edit")})
})
.navigationBarTitle(Text("Notes"))
}
}
SwiftUI 2
In SwiftUI 2 / iOS 14 the navigationBarItems modifier is deprecated.
Instead we should use a toolbar with ToolbarItems.
NavigationView {
List {
// ...
}
.navigationTitle("Notes")
.toolbar {
ToolbarItem(placement: .navigationBarLeading) {
Button("Tap me") {
// action
}
}
ToolbarItem(placement: .navigationBarTrailing) {
Image(systemName: "plus")
}
}
}
You can see the documentation for more ToolbarItemPlacements.
Check the image here
The toolbar() modifier lets us add single or multiple bar button items to the leading and trailing edge of a navigation view, as well as other parts of our view if needed. These might be tappable buttons, but there are no restrictions – you can add any sort of view.
var body: some View {
NavigationView {
ScrollView {
VStack{
}//: VStack
}//: Scroll
.navigationTitle("Settings")
.toolbar(content: {
ToolbarItemGroup(placement: .navigationBarTrailing) {
Button {
presentationMode.wrappedValue.dismiss()
} label: {
Image(systemName: "xmark")
}
}
})
.padding()
}//: Navigation
}
put this from parentViewController
NavigationLink(destination: NotesListView())
