Code to set underline，I want to make the space between the text and the underline larger.
Text("underline text")
.underline()
Underline is a font feature, you can do custom under just by drawing line anywhere needed
var body: some View {
HStack {
Text("Before")
Text("underline text")
.overlay(
Rectangle().frame(height: 1).offset(y: 4)
, alignment: .bottom)
Text("after.")
}
}
How about use a custom view instead of .underline ?
struct MyUnderline: View {
let color: Color = .black
let height: CGFloat = 1
var body: some View {
Rectangle()
.fill(color)
.frame(height: height)
}
}
Text("underline text")
MyUnderline()
.padding(.top, -10)
You could create a custom view that takes the text and underline padding as parameters
struct UnderlinedText: View {
var text: String
var underlinePadding: CGFloat
var body: some View {
VStack (spacing: underlinePadding) {
Text(text)
GeometryReader { proxy in
Rectangle()
.frame(width: proxy.size.width, height: 1)
}
}
}
}
And use it as follows
UnderlinedText(text: "Hello underlined text", underlinePadding: 10.0)

I am trying to animate text to make it scroll across the screen, (using it to make a stock app), I am unable to get it to go completely off the screen can someone please help...
This is what I have so far
let text = "Some text to animate"
private var is = true
var body: some View {
VStack {
Text(text)
.fixedSize()
.frame(width: 100, alignment: is ? .trailing : .leading)
.animation(Animation.linear(duration: 5).repeatForever())
}
A possible solution is to use single Text with .move asymmetric transition.
Here is a simplified demo. Tested with Xcode 13.4 / iOS 15.5
Main part:
var body: some View {
GeometryReader { gp in
VStack {
Text(text)
.fixedSize()
.frame(width: gp.size.width + textWidth, alignment: .trailing)
.id(go)
.transition(transition)
.onAppear{ go.toggle() }
.animation(animation, value: go)
}
}.fixedSize(horizontal: false, vertical: true)
}
Test module on GitHub
like this? It shifts the text using .offset if go is true.
let text = "Some text to animate"
#State private var go = false
var body: some View {
VStack {
Text(text)
.fixedSize()
.frame(width: 100)
.offset(x: go ? 300 : 0, y: 0)
.animation(Animation.linear(duration: 3).repeatForever(), value: go)
.onAppear{self.go.toggle()}
}
}
I am trying to make a SwiftUI TextEditor with a Divider that adapts its position to stay under the bottom-most line of text inside of a edit-bio section of the app.
Note: I have a frame on my TextEditor so that it doesn't take up the whole-screen
Right now the Divider is static and stays in one place. Is there a built-in way to make the divider stay under the bottom most line of text?
I would think the Spacer would have given me this behavior?
Thank you!
struct EditBio: View {
#ObservedObject var editProfileVM: EditProfileViewModel
var body: some View {
VStack(spacing: 10) {
TextEditor(text: $editProfileVM.bio)
.foregroundColor(.white)
.padding(.top, 70)
.padding([.leading, .trailing], 50)
.frame(minWidth: 100, idealWidth: 200, maxWidth: 400, maxHeight: 200, alignment: .center)
Divider().frame(height: 1).background(.white)
Spacer()
}
}
}
It is doing exactly what you told it to do. But a background color on your TextEditor. You will see that it has a height of 200 + a spacing of 10 from the VStack.
I changed your code to make it obvious:
struct EditBio: View {
#State var editProfileVM = ""
var body: some View {
VStack(spacing: 10) {
TextEditor(text: $editProfileVM)
.foregroundColor(.white)
.padding(.top, 70)
.padding([.leading, .trailing], 50)
.frame(minWidth: 100, idealWidth: 200, maxWidth: 400, maxHeight: 200, alignment: .center)
.background(Color.gray)
Divider().frame(height: 1).background(.red)
Spacer()
}
}
}
to produce this:
You can see the TextEditor naturally wants to be taller than 200, but that is limiting it. Therefore, the Spacer() is not going to cause the TextEditor to be any smaller.
The other problem that setting a fixed frame causes will be that your text will end up off screen at some point. I am presuming what you really want is a self sizing TextEditor that is no larger than it's contents.
That can be simply done with the following code:
struct EditBio: View {
#State var editProfileVM = ""
var body: some View {
VStack(spacing: 10) {
SelfSizingTextEditor(text: $editProfileVM)
// Frame removed for the image below.
// .frame(minWidth: 100, idealWidth: 200, maxWidth: 400, maxHeight: 200, alignment: .center)
.foregroundColor(.white)
// made the .top padding to be .vertical
.padding(.vertical, 70)
.padding([.leading, .trailing], 50)
.background(Color.gray)
Divider().frame(height: 5).background(.red)
Spacer()
}
}
}
struct SelfSizingTextEditor: View {
#Binding var text: String
#State var textEditorSize = CGSize.zero
var body: some View {
ZStack {
Text(text)
.foregroundColor(.clear)
.copySize(to: $textEditorSize)
TextEditor(text: $text)
.frame(height: textEditorSize.height)
}
}
}
extension View {
func readSize(onChange: #escaping (CGSize) -> Void) -> some View {
background(
GeometryReader { geometryProxy in
Color.clear
.preference(key: SizePreferenceKey.self, value: geometryProxy.size)
}
)
.onPreferenceChange(SizePreferenceKey.self, perform: onChange)
}
func copySize(to binding: Binding<CGSize>) -> some View {
self.readSize { size in
binding.wrappedValue = size
}
}
}
producing this view:
So I'm building my first App and trying to get some Text below the Button, but it should still be a part of the button. So thats what i got:
Button{
print("tapped")
} label: {
Image("Wand")
.resizable()
.frame(width: 100, height: 100)
}
.font(.title3)
.background(Color.gray)
.foregroundColor(.black)
.cornerRadius(20)
It looks like this:
But I want is this:
I've tried putting a VStack into the Label, but the Text stays in the gray button
I think it may help you
public struct VerticalLabelStyle: LabelStyle {
public let spacing: CGFloat
public init(spacing: CGFloat = 8) {
self.spacing = spacing
}
public func makeBody(configuration: Configuration) -> some View {
VStack(alignment: .center, spacing: spacing) {
configuration.icon
configuration.title
}
}
}
public struct ContentView: View {
#State private var text: String = ""
public var body: some View {
Label {
Text(text)
} icon: {
Image(systemName: "gamecontroller.fill")
.resizable()
.frame(width: 44, height: 44, alignment: .center)
}
.frame(width: 100, height: 100)
.labelStyle(VerticalLabelStyle())
.onTapGesture(perform: onTap)
}
func onTap() {
text = "tapped"
}
}
If you have some questions please ask
Your idea with a VStack is the correct way. You just have to keep in mind where to place your modifiers. In your case you placed them on the button level. Meaning they are applied to the entire label, which is the reason why your Text is inside the gray background. Just update also the place of your modifiers inside your VStack.
Here is are short example:
Button {
// Your button action
} label: {
VStack {
RoundedRectangle(cornerRadius: 25)
.frame(width: 100, height: 100)
.padding()
.background(Color.black) // new position of background modifier that is only applied on your Image (here a rectangle)
Text("Foo")
.font(.title3)
.foregroundColor(.black)
// These modifiers could stay on button level, but I moved them here to explicitly show where they applied
}
}
Keep in mind you can put any view inside the label of your button and that in this case the Text is part of the button and will trigger the action if a user taps on it. If you only want that the Image is the tap action wrap your button inside a VStack containing only the Image and a Text as the second part of the Stack like this:
VStack {
Button {
// Your button action
} label: {
VStack {
RoundedRectangle(cornerRadius: 25)
.frame(width: 100, height: 100)
.padding()
.background(Color.black)
}
}
Text("Foo")
.font(.title3)
.foregroundColor(.black)
}
I am developing an App that supports multiple Profiles. I really like the way Apple displays the Profile Icon next to the Large Navigation Bar Title in all their Apps. See the Screenshot below:
My Question is the following:
Is it possible to achieve this in SwiftUI? And if so, how?
If it's not possible in pure SwiftUI, how can I achieve it including UIKit Code?
Thanks for your help.
I solved this by using SwiftUI-Introspect, to "Introspect underlying UIKit components from SwiftUI".
Here is an example of a view:
struct ContentView: View {
#State private var lastHostingView: UIView!
var body: some View {
NavigationView {
ScrollView {
ForEach(1 ... 50, id: \.self) { index in
Text("Index: \(index)")
}
.frame(maxWidth: .infinity)
}
.navigationTitle("Large title")
.introspectNavigationController { navController in
let bar = navController.navigationBar
let hosting = UIHostingController(rootView: BarContent())
guard let hostingView = hosting.view else { return }
// bar.addSubview(hostingView) // <--- OPTION 1
// bar.subviews.first(where: \.clipsToBounds)?.addSubview(hostingView) // <--- OPTION 2
hostingView.backgroundColor = .clear
lastHostingView?.removeFromSuperview()
lastHostingView = hostingView
hostingView.translatesAutoresizingMaskIntoConstraints = false
NSLayoutConstraint.activate([
hostingView.trailingAnchor.constraint(equalTo: bar.trailingAnchor),
hostingView.bottomAnchor.constraint(equalTo: bar.bottomAnchor, constant: -8)
])
}
}
}
}
Bar content & profile picture views:
struct BarContent: View {
var body: some View {
Button {
print("Profile tapped")
} label: {
ProfilePicture()
}
}
}
struct ProfilePicture: View {
var body: some View {
Circle()
.fill(
LinearGradient(
gradient: Gradient(colors: [.red, .blue]),
startPoint: .topLeading,
endPoint: .bottomTrailing
)
)
.frame(width: 40, height: 40)
.padding(.horizontal)
}
}
The .frame(width: 40, height: 40) & hostingView.bottomAnchor constant will need to be adjusted to your needs.
And the results for each option (commented in the code):
Option 1
Option 2
View sticks when scrolled
View disappearing underneath on scroll
Without NavigationView
I done this with pure SwiftUI. You have to replace the Image("Profile") line with your own image (maybe from Assets or from base64 data with UIImage).
HStack {
Text("Apps")
.font(.largeTitle)
.fontWeight(.bold)
Spacer()
Image("Profile")
.resizable()
.scaledToFit()
.frame(width: 40, height: 40)
.clipShape(Circle())
}
.padding(.all, 30)
This products following result:
With NavigationView
Let's assume that you have NavigationView and inside that there's only ScrollView and .navigationTitle. You can add that profile image there by using overlay.
NavigationView {
ScrollView {
//your content here
}
.overlay(
ProfileView()
.padding(.trailing, 20)
.offset(x: 0, y: -50)
, alignment: .topTrailing)
.navigationTitle(Text("Apps"))
}
Where ProfileView could be something like this:
struct ProfileView: View {
var body: some View {
Image("Profile")
.resizable()
.scaledToFit()
.frame(width: 40, height: 40)
.clipShape(Circle())
}
}
The result will be like this...
...which is pretty close to the App Store:
Using SwiftUI, I am trying to center a View on the screen and then give it a header and/or footer of variable heights.
Using constraints it would look something like this:
let view = ...
let header = ...
let footer = ...
view.centerInParent()
header.pinBottomToTop(of: view)
footer.pinTopToBottom(of: view)
This way, the view would always be centered on the screen, regardless of the size of the header and footer.
I cannot figure out how to accomplish this with SwiftUI. Using any type of HStack or VStack means the sizes of the header and footer push around the view. I would like to avoid hardcoding any heights since the center view may vary in size as well.
Any ideas? New to SwiftUI so advice is appreciated!
If I correctly understood your goal (because, as #nayem commented, at first time seems I missed), the following approach should be helpful.
Code snapshot:
extension VerticalAlignment {
private enum CenteredMiddleView: AlignmentID {
static func defaultValue(in dimensions: ViewDimensions) -> CGFloat {
return dimensions[VerticalAlignment.center]
}
}
static let centeredMiddleView = VerticalAlignment(CenteredMiddleView.self)
}
extension Alignment {
static let centeredView = Alignment(horizontal: HorizontalAlignment.center,
vertical: VerticalAlignment.centeredMiddleView)
}
struct TestHeaderFooter: View {
var body: some View {
ZStack(alignment: .centeredView) {
Rectangle().fill(Color.clear) // !! Extends ZStack to full screen
VStack {
Header()
Text("I'm on center")
.alignmentGuide(.centeredMiddleView) {
$0[VerticalAlignment.center]
}
Footer()
}
}
// .edgesIgnoringSafeArea(.top) // uncomment if needed
}
}
struct Header: View {
var body: some View {
Rectangle()
.fill(Color.blue)
.frame(height: 40)
}
}
struct Footer: View {
var body: some View {
Rectangle()
.fill(Color.green)
.frame(height: 200)
}
}
struct SwiftUIView_Previews: PreviewProvider {
static var previews: some View {
TestHeaderFooter()
}
}
Here's the code:
struct ContentView: View {
var body: some View {
GeometryReader { geometry in
VStack(alignment: .leading) {
Rectangle()
.fill(Color.gray)
.frame(width: geometry.size.width, height: geometry.size.height * 0.1, alignment: .center)
Text("Center")
.frame(width: geometry.size.width, height: geometry.size.height * 0.2, alignment: .center)
Rectangle()
.fill(Color.gray)
.frame(width: geometry.size.width, height: geometry.size.height * 0.1, alignment: .center)
}
}
}
}
using GeometryReader you can apply the dynamic size for your views.
also here is screenshot for above code
put Spacer() between header view and footer view.
headerview()
Spacer()
footerview()
