I've got a TextField in SwiftUI that is centered on the screen. I want to add a pencil icon immediately. to the left of it to indicate that it is editable - how can I do this? I've tried embedding both the TextField and Image in an HStack like this:
HStack {
Spacer()
Image(systemName: "pencil")
TextField(...)
}
But that only yields something like this:
where the textfield is no longer centered and the pencil is aligned to the left of the screen.
Any guidance is appreciated.
this should do it:
TextField("", text: $input)
.overlay(alignment: .leading) {
Image(systemName: "pencil")
.offset(x: -24, y: 0)
}
struct CustomTextFieldView: View {
#State private var text: String = ""
var body: some View {
VStack(alignment: .leading) {
textfeild
.padding()
}
}
var textfeild: some View {
HStack {
Image(systemName: "pencil")
TextField("Edit me!", text: $text)
}
.textFieldStyle(DefaultTextFieldStyle())
}
}
struct CustomTextFieldView_Previews: PreviewProvider {
static var previews: some View {
CustomTextFieldView()
}
}

I want to have the TextEditor1 to be on the bottom of the app, then when user taps on the TextEditor1 to type the message, the TextEditor1 should attached to the keyboard and move up with it. I used the following code, it attaches to it through the .toolbar, but don't know how to make TextEditor1 stay in the bottom of the app etc and then move up with the keyboard. Image is attached for further clarification.
import SwiftUI
struct ContentView: View {
#State var textTyped: String = "this is textttt"
var body: some View {
TextEditor (text: $textTyped)
.toolbar {
ToolbarItemGroup(placement: .keyboard) {
TextEditor1()
}
}
.frame(height: 200, alignment: .leading)
.padding(.horizontal, 10)
}
}
struct TextEditor1: View {
#State var textTyped: String = "this is textttt"
var body: some View {
TextEditor (text: $textTyped)
.frame(height: 200, alignment: .leading)
.padding(.horizontal, 10)
}
}
Is this what you want? I also put a colored .background() on to see the outlines of the TextEditor. I find it helps to be able to visualize the extent of the views.
struct ContentView: View {
#State var textTyped: String = "this is textttt"
var body: some View {
VStack {
Spacer()
TextEditor (text: $textTyped)
.frame(height: 200, alignment: .leading)
// .padding(.horizontal, 10)
.padding()
.background(Color.yellow.opacity(0.2))
}
}
}
I have this example. Why is there this space at top and bottom of the VStack? The borders of the inner views doesn't seem to be as high as the border of the VStack. I think it has something to do with the LazyHGrid!? Thanks for an answer.
struct ContentView: View{
let names = ["house","creditcard"]
var body: some View{
VStack{
Text("skldfjsjf")
Text("klsadjf")
Text("lksajf")
ScrollView(.horizontal){
LazyHGrid(
rows: [GridItem(.flexible(minimum: 40)),GridItem(.flexible(minimum: 40))],
spacing: 10) {
ForEach(names, id: \.self) { icon in
Image(systemName: icon)
.padding()
}
}
.border(Color.orange)
}
.border(Color.green)
}
.frame(width: UIScreen.main.bounds.width * 0.9)
.border(Color.black)
}
}
I'm new to SwiftUI, but I think you want the content in your VStack to be top hugging?
struct ContentView: View {
let names = ["house","creditcard"]
var body: some View{
VStack (spacing:0) { //THIS HERE FOR NO SPACE FOR VSTACK INTERNAL VIEWS
Text("skldfjsjf")
Text("klsadjf")
Text("lksajf")
ScrollView(.horizontal){
LazyHGrid(
rows: [GridItem(.flexible(minimum: 40)),GridItem(.flexible(minimum: 40))],
spacing: 10) {
ForEach(names, id: \.self) { icon in
Image(systemName: icon)
.padding()
}
}
.border(Color.orange)
}
.border(Color.green)
Spacer() //THIS HERE TO MAKE IT TOP HUGGING
}
.frame(width: UIScreen.main.bounds.width * 0.9)
.border(Color.black)
}
}
I have a VStack wrapped around a NavigationView. I made a NavigationTitle by adding the modifier to VStack. However, my title is not appearing near the top of the screen as it should.
Here is my code:
NavigationView{
VStack{
Image(club.image)
.resizable()
.scaledToFit()
.frame(height: 300)
Text(club.name)
.font(.system(size: 40, weight: .black))
HStack(alignment: .center, spacing: 20){
Label(title: {
Text(club.league)
.foregroundColor(.secondary)
}, icon: {
Image(systemName: "location.north.circle.fill")
.foregroundColor(.blue)
})
Label(title: {
Text(club.netWorth)
.foregroundColor(.secondary)
}, icon: {
Image(systemName: "dollarsign.circle.fill")
.foregroundColor(.blue)
})
}
}.navigationTitle(club.name)
}
I have tried adding the '.navigationTitle' modifier to the NavigationView as well, but that isn't working.
Here is an image as well:

Does anybody have a solution to this?
As lorem ipsum has mentioned. It's as simple as removing the extra NavigationView. When using a Navigation Link it's assumed that it's within a NavigationView. So you only need to declare it once in the root view. If you wanted additional NavigationLink you'd add it without a NavigationView.
struct ContentView: View {
var body: some View {
NavigationView {
VStack {
Text("Chelsea")
NavigationLink("Second View Link", destination: SecondView())
}
.navigationTitle("Chelsea")
}
}
}
struct SecondView: View {
var body: some View {
VStack {
Text("Second View")
}
.navigationTitle("Second View")
}
}
Goal:
1- Shows a view (Blue) that covers entire screen
2- When tapped on bottom (top right corner), it shows an HStack animating right side HStack (Green) "Slide Offset animation".
import SwiftUI
struct ContentView: View {
#State var showgreen = false
var body: some View {
NavigationView {
HStack {
Rectangle()
.foregroundColor(.blue)
if showgreen {
Rectangle()
.foregroundColor(.green)
.offset(x: showgreen ? 0 : UIScreen.main.bounds.width)
.animation(.easeInOut)
}
}
.navigationBarItems(trailing:
Button(action: { self.showgreen.toggle() }) {
Image(systemName: "ellipsis")
})
}
.navigationViewStyle(StackNavigationViewStyle())
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView()
.colorScheme(.dark)
.previewDevice("iPad Pro (12.9-inch) (3rd generation)")
}
}
The code works, however I cannot get the Green "Slide Offset animation" to work. Really appreciate any help! : )
Instead of using the if conditional, you need the green rectangle to be already present, and just offscreen. When showgreen toggles, you need to shrink the size of the blue rectangle, which will make room for the green rectangle.
struct ContentView: View {
#State var showgreen = false
var body: some View {
NavigationView {
HStack {
Rectangle()
.foregroundColor(.blue)
.frame(width: showgreen ? UIScreen.main.bounds.width / 2 : UIScreen.main.bounds.width)
.animation(.easeInOut)
Rectangle()
.foregroundColor(.green)
.animation(.easeInOut)
}
.navigationBarItems(trailing:
Button(action: { self.showgreen.toggle() }) {
Image(systemName: "ellipsis")
})
}
.navigationViewStyle(StackNavigationViewStyle())
}
}
I want to set an image in the titleView of NavigationBar in SwiftUI, as we do in UIKit
navigationItem.titleView = UIImageView(image: UIImage(named: "logo"))
this is how we do it in UIKit.
anyone know how to do it?
Here's how to do it:
Add SwiftUIX to your project.
Set your custom title view via View.navigationBarTitleView(_:displayMode:)
Example code:
struct ContentView: View {
public var body: some View {
NavigationView {
Text("Hello World")
.navigationBarTitleView(MyView())
}
}
}
Simple, Just add your root view into ZStack with top alignment and add your custom center view after root view
struct CenterNavigattionBar: View {
var body: some View {
ZStack(alignment: .top){
//Root view with empty Title
NavigationView {
Text("Test Navigation")
.navigationBarTitle("",displayMode: .inline)
.navigationBarItems(leading: Text("Cancle"), trailing: Text("Done"))
}
//Your Custom Title
VStack{
Text("add title and")
.font(.headline)
Text("subtitle here")
.font(.subheadline)
}
}
}
}
Before Image
After Image
Just use a toolbar.
You can add any views
import SwiftUI
struct HomeView: View {
// MARK: - Initializer
init() {
let appearance = UINavigationBar.appearance()
appearance.isOpaque = true
appearance.isTranslucent = false
appearance.barTintColor = UIColor(named: "background")
appearance.shadowImage = UIImage()
}
// MARK: - View
// MARK: Public
var body: some View {
NavigationView {
VStack(spacing: 20) {
Text("Hello")
Text("Navigation Bar Test")
}
.navigationBarTitleDisplayMode(.inline)
.navigationBarItems(leading: leadingBarButtonItems, trailing: trailingBarButtonItems)
.toolbar {
ToolbarItem(placement: .principal) {
VStack {
Text("Title").font(.headline)
Text("Subtitle").font(.subheadline)
}
}
}
}
}
// MARK: Private
private var leadingBarButtonItems: some View {
Button(action: {
}) {
Text("Left Button")
.font(.system(size: 12, weight: .medium))
}
}
private var trailingBarButtonItems: some View {
HStack {
Button(action: {
}) {
Text("R1\nButton")
.font(.system(size: 12, weight: .medium))
.multilineTextAlignment(.center)
}
Button(action: {
}) {
Text("R2\nButton")
.font(.system(size: 12, weight: .medium))
.multilineTextAlignment(.center)
}
}
}
}
Currently, you can't.
There are two overloads for .navigationBarTitle(), taking either a Text view or a type conforming to StringProtocol. You can't even pass in a modified view like Text("Title").font(.body). This would be a great feature, I'd submit a feature request: http://feedbackassistant.apple.com
Maybe this works for you?
Basically:
Use GeometryReader to get the width of the screen
Have NavigationBarItems(leading: HStack {Spacer() Image("name").resizable().frame(width:..., height: ..., alignment: .center Spacer()}.frame(width:geometry.size.width)
Example code:
struct ContentView: View {
var body: some View {
NavigationView {
GeometryReader { geometry in
Text("Hello, world!")
.padding()
.navigationTitle("test")
.navigationBarItems(leading: HStack {
Spacer()
Image("money")
.resizable()
.frame(width: 50, height: 50, alignment: .center)
Spacer()
}
.frame(width: geometry.size.width)
)
}
}
}
}
