I am trying to get the size of a button. The button's frame size is dynamic based on the text size. How can I do this?
I tried wrapping this in a GeometryReader, and reading the geo.size.height, etc, but this returned 10 every time, and messed up the layout (somehow actually gave the button that height).
I don't know a way to do this that doesn't involve GeometryReader, have searched and found nothing.
Button(action: {
//
}) {
Text(options[i])
.font(.system(.headline, design: .rounded))
.frame(maxWidth: .infinity, alignment: .leading)
.foregroundColor(Color.init(red: 0.3, green: 0.3, blue: 0.3))
.frame(alignment: .leading)
.padding()
.background(
RoundedRectangle(cornerRadius: 12)
.fill(Color.white)
)
}
To get the size of a view, add a GeometryReader as a .background. This needs to contain another view, and when that appears you have
Button(action: {
//
}) {
Text("something")
.font(.system(.headline, design: .rounded))
.frame(maxWidth: .infinity, alignment: .leading)
.foregroundColor(Color.init(red: 0.3, green: 0.3, blue: 0.3))
.frame(alignment: .leading)
.padding()
.background(
RoundedRectangle(cornerRadius: 12)
.fill(Color.white)
)
.background {
GeometryReader { proxy in
Color.clear
.onAppear {
print(proxy.size)
}
}
}
}

I’m trying to align the bottom of two Text but the larger one looks like thismy widget looks like this. I don’t know why there’s still some space below this Text view.
This is my code:
var body: some View {
GeometryReader{geometry in
ZStack(alignment: .center){
Image("background")
.resizable()
VStack(){
HStack(alignment: .bottom){
Text("3")
.lineLimit(1)
.font(.bold(.system(size: 100))())
.minimumScaleFactor(0.1)
.foregroundColor(Color.white)
.frame(width: nil, height: geometry.size.height/3, alignment: .bottom)
.lineLimit(1)
.shadow(radius: 2)
Text("cups")
.foregroundColor(Color.white)
.font(.system(size: 12))
.shadow(radius: 2)
}
Text("Next cup on")
.foregroundColor(Color.white)
.font(.system(size: 10))
.shadow(radius: 2)
.opacity(0.5)
Text("10 : 00")
.foregroundColor(Color.white)
.font(.system(size: 12))
.shadow(radius: 1)
.opacity(0.5)
}
}
}
}
What I want is the number 3’s bottom aligned to “cups”’s bottom.
Thanks!
Instead of .bottom, you can use .lastTextBaseline as your HStack alignment:
HStack(alignment: .lastTextBaseline) {
Text("Hello").font(.system(size: 40))
Text("World").font(.system(size: 10))
}
So basically this is my code.
Text("Melbourne, Victoria")
.font(.largeTitle)
.fontWeight(.bold)
.foregroundColor(Color.white)
.padding(.bottom, 30)
Image(systemName: "moon.fill")
.foregroundColor(Color.white)
.font(.system(size: 60))
Text("Today")
.font(.title)
.fontWeight(.medium)
.foregroundColor(Color.white)
Text("34°C")
.font(.title3)
.fontWeight(.medium)
.foregroundColor(Color.white)
Spacer()
HStack {
Image(systemName: "sun.max.fill")
.foregroundColor(Color.yellow)
.font(.system(size: 40))
.padding(.bottom, 550)
Text("Mon 34°C")
.font(.title)
.fontWeight(.medium)
.foregroundColor(Color.white)
.padding(.bottom, 550)
}
}
.background(
Image("night")
.ignoresSafeArea()
)
I want to make more of the days in this weather app each with it's on SF Symbol and everything is inside this VStack. And the days and SF symbols are inside a HStack to keep them horizontal. But if I want to put more of those the next time I do it they go next to each other but the symbol goes on top look at this.
This is the image with only 1 of those days
And this one is when I put more than 1 but its next to each other when I want them vertically aligned.
This is the one if I put them in another VStack which makes the SF symbol go above the text
IS there any solution to this?
The problem is your .padding(.bottom, 550).
Image(systemName: "sun.max.fill")
.foregroundColor(Color.yellow)
.font(.system(size: 40))
.padding(.bottom, 550) /// here!
It's currently attached to your first Image. As a result, the HStack is stretched vertically and it appears as though the first Image is higher up than second one.
To fix, move both .padding(.bottom, 550)s to outside your HStack.
You have quite a lot of arbitrary values for padding. You should have your layout adapt to various devices, rather than hard-coding that .bottom spacing for example.
Working example:
struct ContentView: View {
var body: some View {
VStack(spacing: 40) {
Text("Melbourne, Victoria")
.font(.largeTitle)
.fontWeight(.bold)
.foregroundColor(Color.white)
VStack {
Image(systemName: "moon.fill")
.foregroundColor(Color.white)
.font(.system(size: 60))
Text("Today")
.font(.title)
.fontWeight(.medium)
.foregroundColor(Color.white)
Text("34°C")
.font(.title3)
.fontWeight(.medium)
.foregroundColor(Color.white)
}
VStack(spacing: 10) {
HStack {
Image(systemName: "sun.max.fill")
.renderingMode(.original)
.font(.system(size: 40))
Text("Mon 34°C")
.font(.title)
.fontWeight(.medium)
.foregroundColor(Color.white)
}
HStack {
Image(systemName: "cloud.sun.fill")
.renderingMode(.original)
.font(.system(size: 40))
Text("Tue 28°C")
.font(.title)
.fontWeight(.medium)
.foregroundColor(Color.white)
}
}
Spacer()
}
.frame(maxWidth: .infinity)
.background(
Color(red: 0.34, green: 0.36, blue: 0.71)//Image("night")
.ignoresSafeArea()
)
}
}
Result:
Although there is already an outer VStack, they are nested VStacks because they have different amounts of padding. Multiple views are grouped together, and then those are grouped together with larger paddings to separate them.
Bonus
SF Symbols colors
Use:
.renderingMode(.original)
Rather than:
.foregroundColor(Color.yellow)
To color the SF Symbols with the default colors, as shown in the above example.
Align days
You can align the days across each HStack with a custom alignment guide. Use the following:
extension HorizontalAlignment {
struct LeadingDay: AlignmentID {
static func defaultValue(in context: ViewDimensions) -> CGFloat {
context[.leading]
}
}
static let leadingDay = HorizontalAlignment(LeadingDay.self)
}
Making the other following changes:
VStack(alignment: .leadingDay, spacing: 10) { // <- HERE
HStack {
Image(systemName: "sun.max.fill")
.renderingMode(.original)
.font(.system(size: 40))
Text("Mon 34°C")
.font(.title)
.fontWeight(.medium)
.foregroundColor(Color.white)
.alignmentGuide(.leadingDay) { d in // <- HERE
d[.leading]
}
}
HStack {
Image(systemName: "cloud.sun.fill")
.renderingMode(.original)
.font(.system(size: 40))
Text("Tue 28°C")
.font(.title)
.fontWeight(.medium)
.foregroundColor(Color.white)
.alignmentGuide(.leadingDay) { d in // <- HERE
d[.leading]
}
}
}
Result:
The color.red is my widgets main background but I would like to add a black background to the top behind the text "Line1" and image "2". So basically a black bar that stretches across the top under the text and image.
var body: some View {
ZStack {
Color.red
VStack(alignment: .leading, spacing: 0) {
HStack {
Text("Line1")
.foregroundColor(.orange)
.bold()
.font(.system(size: 17.5))
.padding(.top)
Spacer()
Image("2")
.resizable()
.frame(width: 25, height: 25)
.padding(.top)
}
.padding(.horizontal)
.border(Color.green)
VStack(alignment: .leading) {
Image("2")
.resizable()
.frame(width: 67, height: 30)
Text("State")
.foregroundColor(Color.green)
.font(.system(size: 15))
Text("1")
.foregroundColor(Color.blue)
.font(.system(size: 10))
.opacity(0.5)
Spacer()
Spacer()
}
.padding(.horizontal)
.border(Color.blue)
}
}
}
You can add a .background modifier to your first HStack:
HStack {
//content here
}
.padding(.horizontal)
.border(Color.green)
.background(Color.black)
Keep in mind that order of modifiers is important, so if you put the background before the padding, the padding will not have that background color -- that's why I used it last.
I have an image that needs to be put in the top center of my view. How can I do so?
struct MyTextField: View
{
#ObservedObject var model: TextFieldModel
var body: some View
{
VStack(alignment: .leading, spacing: -60)
{
Color.black.position(CGPoint(x: 200, y: -50)).frame(width: 417, height: 120,
alignment: .top)
.background(Image(("appIconLogo")).resizable().frame(width: 50, height: 50))
//Spacer(minLength: 5)
VStack(alignment: .leading, spacing: 30)
{
Text("Welcome!")
.font(.system(size: 60, design: .rounded))
.foregroundColor(.black)
iTextField("Search Your Ticker", text: $model.text, isEditing: $model.isEditing)
.foregroundColor(.black)
.showsClearButton(true)
.onReturn
{
print($model.text)
NotificationCenter.default.post(name: Notification.Name(rawValue:
"isValidTicker"), object: nil)
}
.foregroundColor(.black)
.style(height: 58, font: nil, paddingLeading: 25, cornerRadius: 6,
hasShadow: true, image: Image(systemName: "magnifyingglass"))
.foregroundColor(.black)
}
}
.position(CGPoint(x: 200.0, y: 150.0))
.padding()
}
}
But my View looks like this. How can I move my image to the top center of the page where the black color is?
Here is a demo of possible layout. Prepared with Xcode 12.1 / iOS 14.1.
struct MyTextField: View
{
var body: some View
{
VStack {
Color.black
.frame(height: 120)
.overlay(Image(("plant")).resizable().frame(width: 50, height: 50))
.edgesIgnoringSafeArea(.top)
VStack(alignment: .leading, spacing: 30)
{
Text("Welcome!")
.font(.system(size: 60, design: .rounded))
.foregroundColor(.black)
.padding(.leading)
// .. other code
}.frame(maxWidth: .infinity, alignment: .leading)
}.frame(maxHeight: .infinity, alignment: .top)
}
}
It's a little confusing what you are trying to do in your code, but I think this might get you started. I made a background layer that extends to the edge of the screen, and then put a Content layer on top of it, where you can put the Image at the top of the VStack.
You should try to avoid setting exact width/height/CGPoints whenever possible in SwiftUI.
var body: some View {
ZStack {
// Background
Color.white
.edgesIgnoringSafeArea(.all)
// Content
VStack(spacing: 20) {
Image(systemName: "heart.fill") // Image here
Text("Welcome!") // Title
.font(.system(size: 60, design: .rounded))
.frame(maxWidth: .infinity, alignment: .leading)
.foregroundColor(.black)
TextField("Search your ticker", text: $textFieldText) // Textfield
.frame(height: 50)
.background(Color.gray)
.cornerRadius(10)
Spacer()
}
.padding()
}
}
I have problem in SwiftUI. I created ScollView and post into some Views. (News Articles). When i launch app - ScrollView and content inside appears in dioganal way, like animation. But i need to launch app and get static ScrollView with views inside it, without any movements.
Also the same problem occurred when i open sheet view with ScrollView and Text Blocks inside. It also appers first 0.3s like dioganaly way. But how can i achive static ? Thank you all )
Place i use sheet controller (Also this block in ScrollView)
ScrollView{
ArticlePreView(image: "one", category: "Category", heading: "Header", author: "some text").onTapGesture {
self.showingDetail.toggle()
}.sheet(isPresented: $showingDetail) {
Home()
}
}
Image to understand
Video of problem
And this is place of my sheet controller
ScrollView() {
VStack {
HStack {
Text("Soem long title")
.font(.title)
.fontWeight(.bold)
Spacer()
Button(action: {
}) {
HStack {
Image(systemName: "heart.fill")
.foregroundColor(Color.gray)
}
.padding()
}
.background(
Circle()
.fill(Color.neuBackground)
)
.shadow(color: .dropShadow, radius: 15, x: 10, y: 10)
.shadow(color: .dropLight, radius: 15, x: -10, y: -10)
}
.padding(.horizontal, 35)
.padding(.top, 25)
Text("long text")
.multilineTextAlignment(.leading)
.foregroundColor(.gray)
.padding(.horizontal, 30)
.padding(.top, 20)
Text("long text")
.multilineTextAlignment(.leading)
.foregroundColor(.gray)
.padding(.horizontal, 30)
.padding(.top, 20)
Text("long text")
.multilineTextAlignment(.leading)
.foregroundColor(.gray)
.padding(.horizontal, 30)
.padding(.top, 20)
Text("long text")
.multilineTextAlignment(.leading)
.foregroundColor(.gray)
.padding(.horizontal, 30)
.padding(.top, 20)
Spacer(minLength: 50)
}
}.frame(width: UIScreen.main.bounds.size.width)
Fixed using
.frame(width: UIScreen.main.bounds.size.width)
.fixedSize()
SwiftUI is not adaptive
