I'm trying to figure out why the navigation title is not working with some devices, but I'm not able to figure out this issue. Can any one please help me to find out this issue, why the navigation title shows only the first 3 letters and after showing?
I have attached the Screenshot also please check.
iPhone 11 Device
iPhone 11 Simulator
Code:-
var body: some View {
ZStack {
Color.init(ColorConstantsName.MainThemeBgColour)
.ignoresSafeArea()
GeometryReader { geo in
ScrollView(.vertical) {
Text("Testing")
}
}
}
.navigationBarBackButtonHidden(true)
.navigationTitle(CommonAllString.BlankStr)
.navigationViewStyle(.stack)
.navigationBarTitleDisplayMode(.inline)
.navigationBarItems(leading:AnyView(leadingButton),trailing:AnyView(self.trailingButton))
.foregroundColor(Color.white)
}
var trailingButton: some View {
HStack {
Image(systemName: ImageConstantsNameForChatScreen.PersonImg)
.padding(.trailing)
Image(ImageConstantsName.DTRShareIconImg)
.resizable().frame(width: 20, height: 20)
}
}
Below Code Working:-
struct PSScreen: View {
var body: some View {
ZStack {
Color.init("Colour")
.ignoresSafeArea()
VStack{
Text("PSScreen")
}
}
.navigationBarBackButtonHidden(true)
.navigationBarTitle("", displayMode: .inline)
.navigationViewStyle(.stack)
.navigationBarTitleDisplayMode(.inline)
.toolbar {
ToolbarItem(placement: .navigationBarLeading) {
leadingButton.frame(width: 50, alignment: .leading)
}
ToolbarItem(placement: .navigationBarTrailing) {
trailingButton
}
}.foregroundColor(Color.white)
}
var leadingButton: some View {
HStack{
Text("Profile")
}
}
var trailingButton: some View {
HStack {
Image(systemName: "Person")
.padding(.trailing)
Image("Share")
.resizable().frame(width: 20, height: 20)
}
}
}

This is my code:
struct Account: View {
var body: some View {
VStack {
ScrollView {
HStack {
Text("Account")
.font(.largeTitle)
.fontWeight(.bold)
Spacer(minLength: 0)
}
.padding()
.background(Color.indigo)
VStack {
Text("Doe, John Jack")
.font(.title)
Divider()
.foregroundColor(Color.indigo)
HStack {
Text("")
}
}
Spacer(minLength: 0)
VStack {
Button(action: {
}) {
Text("Log Out")
.foregroundColor(.red)
.fontWeight(.bold)
}
}
}
}
}
}
If you run the code above, you will see that the indigo doesn't go behind the time and battery precentage. How can I make it do that?
Try like this:
struct Account: View {
var body: some View {
VStack {
ScrollView {
HStack {
Text("Account")
.font(.largeTitle)
.fontWeight(.bold)
Spacer(minLength: 0)
}
.padding()
.background(Color.indigo)
VStack {
Text("Doe, John Jack")
.font(.title)
Divider()
.foregroundColor(Color.indigo)
HStack {
Text("")
}
}
Spacer(minLength: 0)
VStack {
Button(action: {
}) {
Text("Log Out")
.foregroundColor(.red)
.fontWeight(.bold)
}
}
}.padding(.top, 66)
}
.background(Color.indigo)
.edgesIgnoringSafeArea(.all)
}
}
You would also have to add some top padding to the ScrollView since ignoring safe area is going to push all your views to the margins
You should ignore the top safe area for this:
.ignoresSafeArea(.container, edges: .top)
Full working example
struct ContentView: View {
var body: some View {
Color
.indigo
.ignoresSafeArea(.container, edges: .top)
}
}
I have a navigation title for a list view. After navigating back and forth, my navigation title is missing. I am new to swiftui and unable to debug. Kindly help.
var body: some View {
NavigationView {
VStack {
TabView(selection: $choice,
content: {
OPListCell()
IPListCell()
})
.tabViewStyle(PageTabViewStyle())
}
.listStyle(PlainListStyle())
.navigationBarTitle("My Patients")
.toolbar {
ToolbarItem(placement: .principal) {
HStack {
Picker(selection: self.$choice, label: Text("")) {
ForEach(0 ..< self.choices.count) {
Text(self.choices[$0])
}
}
.frame(width: 175)
.pickerStyle(SegmentedPickerStyle())
.padding(.leading, 10)
}
}
}
}
}
}
I have tried to use Buttons and Navigation Links from various examples when researched on this channel and on the net. The NavigationLink would be ok, except that the NavigationView is pushing everything down in my view.
I have a view that contains an image and a text like this: ( x Close) but when I use the code below, the Close button is not doing anything.
In ContentView() I have a (?) button that takes me from WalkthroughView(), then to the PageTabView, then to this view, TabDetailsView:
ContentView():
ZStack {
NavigationView {
VStack {
Text("Hello World")
.padding()
.font(.title)
.background(Color.red)
.foregroundColor(.white)
}
.toolbar {
ToolbarItem(placement: .navigationBarLeading) {
Button {
withAnimation {
showOnBoarding = true
}
} label: {
Image(systemName: "questionmark.circle.fill")
}
}
}
}
.accentColor(.red)
.disabled(showOnBoarding)
.blur(radius: showOnBoarding ? 3.0 : 0)
if showOnBoarding {
WalkthroughView(isWalkthroughViewShowing: $isWalkthroughViewShowing)
}
}
.onAppear {
if !isWalkthroughViewShowing {
DispatchQueue.main.asyncAfter(deadline: .now() + 2) {
withAnimation {
showOnBoarding.toggle()
isWalkthroughViewShowing = true
}
}
}
}
WalkthroughView():
var body: some View {
ZStack {
GradientView()
VStack {
PageTabView(selection: $selection)
// shows Previous/Next buttons only
ButtonsView(selection: $selection)
}
}
.transition(.move(edge: .bottom))
}
PageTabView():
var body: some View {
TabView(selection: $selection) {
ForEach(tabs.indices, id: \.self) { index in
TabDetailsView(index: index)
}
}
.tabViewStyle(PageTabViewStyle())
}
below, is the TabDetailsView():
At the top of the view is this Close button, when pressed, should send me back to ContentView, but nothing is happening.
struct TabDetailsView: View {
#Environment(\.presentationMode) var presentationMode: Binding<PresentationMode>
let index: Int
then, inside the body:
VStack(alignment: .leading) {
Spacer()
VStack(alignment: .leading) {
// Button to close each walkthrough page...
Button(action: {
self.presentationMode.wrappedValue.dismiss()
}) {
Image(systemName: "xmark.circle.fill")
Text("Close")
}
.padding(.leading)
.font(.title2)
.accentColor(.orange)
Spacer()
VStack {
Spacer()
Image(tabs[index].image)
.resizable()
.aspectRatio(contentMode: .fit)
.frame(width: 415)
.padding(.leading, 10)
Text(tabs[index].title)
.font(.title)
.bold()
Text(tabs[index].text)
.padding()
Spacer()
}
.foregroundColor(.white)
}
}
if showOnBoarding {
WalkthroughView(isWalkthroughViewShowing: $isWalkthroughViewShowing)
}
Inserting view like above is not a presentation in standard meaning, that's why provided code does not work.
As this view is shown via showOnBoarding it should be hidden also via showOnBoarding, thus the solution is to pass binding to this state into view where it will be toggled back.
Due to deep hierarchy the most appropriate way is to use custom environment value. For simplicity let's use ResetDefault from https://stackoverflow.com/a/61847419/12299030 (you can rename it in your code)
So required modifications:
if showOnBoarding {
WalkthroughView(isWalkthroughViewShowing: $isWalkthroughViewShowing)
.environment(\.resetDefault, $showOnBoarding)
}
and in child view
struct TabDetailsView: View {
#Environment(\.resetDefault) var showOnBoarding
// .. other code
Button(action: {
self.showOnBoarding.wrappedValue.toggle()
}) {
Image(systemName: "xmark.circle.fill")
Text("Close")
}
When I use toolbar group in SwiftUI, there is too much space between elements. I put it with HStack in iOS 13, it is ok. But when I put it with toolbar in iOS 14, there is a problem. How can I fix this?
var muteUser: some View {
NavigationLink(destination: Text("dddd").environmentObject(CurrentUser)) {
Image(systemName: "speaker.slash")
.frame(width: 22, height: 22)
}
}
var friendSetting: some View {
NavigationLink(destination: FriendSettings().environmentObject(CurrentUser)) {
Image(systemName: "gear")
.frame(width: 22, height: 22)
}
}
var body: some View {
GeometryReader { geometry in
if #available(iOS 14.0, *) {
chatView
.toolbar {
ToolbarItem(placement: .principal) {
centerNavBar()
.frame(maxWidth: geometry.size.width*0.75)
}
ToolbarItemGroup(placement: .navigationBarTrailing) {
muteUser
friendSetting
}
}
} else {
chatView
.navigationBarItems(trailing:
HStack(){
centerNavBar()
Spacer()
rightNavBar
}
.frame(width: geometry.size.width*0.75)
)
}
}
}
It looks like this is the standard appearance of two buttons inside ToolbarItemGroup.
You can use a HStack instead:
.toolbar {
ToolbarItem(placement: .principal) {
Image(systemName: "star.fill")
}
ToolbarItem(placement: .navigationBarTrailing) {
HStack {
NavigationLink(destination: Text("dddd").environmentObject(CurrentUser)) {
Image(systemName: "speaker.slash")
.imageScale(.large)
}
NavigationLink(destination: FriendSettings().environmentObject(CurrentUser)) {
Image(systemName: "gear")
.imageScale(.large)
}
}
}
}
Try omitting the .frame(width: 22, height: 22) on the toolbar item Images. I think that’s causing the iOS 14 toolbar to create UIToolbarItems with embedded views instead of simple images.
public struct Frontside: View
{
#Binding public var kanatext: String
public var body: some View
{
ZStack{
RoundedRectangle(cornerRadius: 25, style: .continuous)
.foregroundColor(Color.red)
.frame(width: 160, height: 160)
.zIndex(0)
Text(self.kanatext)
.font(.title)
.fontWeight(.black)
.padding(50)
.zIndex(1)
VStack {
Spacer()
HStack {
Button(action: {
print("button pressed")
}) {
Image(systemName: "xmark.circle")
.font(.title)
}
.mask(Circle())
.opacity(0.4)
Button(action: {
print("button pressed")
}) {
Image(systemName: "checkmark.circle")
.font(.title)
}
.mask(Circle())
.opacity(0.4)
}
}
.zIndex(2)
}
}
}
In the above code snippet, I have used a Zstack to layer different parts of a flash card, a background, the text, and then correct/incorrect buttons. The uppermost layer are the buttons, which appear correctly, but for some reason they are not actually pressable.
Have you tried using onTapGesture? It might have to do with the fact that you're using a ZStack.
Try something like:
Image(systemName: "checkmark.circle")
.font(.title)
.onTapGesture {
print("button pressed")
}
In this case there would be no needed to wrap the Image in a Button.
If this doesn't work add onTapGesture to your VStack and have it be empty.
