I'm trying to get an aligned text-image pairs in swiftui programmatically. Is it possible?
I want the word "Visit" to start from the same position in both rows.
This is my code:
HStack{
Image(systemName: item.leftImage) // A system image name
Text(item.text) // A text representing the item
}
I know that I can add spacing to the HStack itself, but it won't fix my issue.
Since every systemimage provided by apple has a different sizing, I guess that I should programmatically somehow determine the spacing that should be instantiated between each the image to the text.
How can I do that?
I would recommend to use explicit width for image frame, this will fit any symbol automatically and make it centred
HStack{
Image(systemName: item.leftImage)
.frame(width: 28)
Text(item.text)
}
Give the Image a constant frame, like below:
HStack {
Image(systemName: item.leftImage)
.frame(width: 32)
Text(item.text) // A text representing the item
}
HStack takes Vertical alignment as argument. Then the text and icon is vertical alignment.
HStack(alignment: .center)
{
Image(systemName: item.leftImage) // A system image name
Text(item.text) // A text representing the item
}
To align the text, give the image a frame width. You need to determine they maximum width a image can take.
VStack(alignment: .leading)
{
HStack(alignment: .center)
{
Image(systemName: "pause") // A system image name
.frame(width: 50)
Text("Test") // A text representing the item
}
HStack(alignment: .center)
{
Image(systemName: "cloud") // A system image name
.frame(width: 50)
Text("Test") // A text representing the item
}
}

I have a card view:
var body: some View {
VStack {
Text(tip)
.padding(.bottom)
.font(.custom("Roboto-Light", size:10))
Text(tipTitle)
.multilineTextAlignment(.center)
.font(.custom("Roboto-Bold", size:24))
Text(tipMessage)
.font(.custom("Roboto-Light", size:14))
.multilineTextAlignment(.center)
.padding(.top,1)
Image(image)
.resizable()
.aspectRatio(contentMode: .fill)
.frame(width: 200, height: 150)
}
.padding()
.background(Color("grey"))
.cornerRadius(15)
.padding(.horizontal)
}
When I use these cards, the padding varies based on the text I add:
How can we fix the card size so the sizes for the cards are always the same?
A VStack will hug its contents, making itself as small as possible. If you want it to fill the available space, then make the contents as wide as possible. Your variable element is probably Text(tipMessage), so you should add a modifier to it, before the padding modifier, to make it fill the available space:
.frame(maxWidth: .infinity, alignment: .center)
A more complete screenshot showing the actual card contents would have been more helpful than the one you posted.
I have two items in an HStack. I want one of them to be perfectly horizontally centered and the other to be on the left side (have an alignment of .leading). Here is my code so far:
HStack {
Text("1")
.frame(alignment: .leading)
Text("Hello")
.frame(alignment: .center)
}
I have figured out that the .overlay method works. However, I still want Text("Hello") to be aware of the position of Text("1") so that if Text("Hello") were a longer string, it would know not to cover up Text("1"), which is exactly what happens when the .overlay function is used. So I'm wondering if there are any other solutions.
You can add one more Text view inside HStack as hidden which have the same content as your left align text view along with Spacer. Something like this.
HStack {
Text("1")
Spacer()
Text("Good Morning, Hello World. This is long message")
.multilineTextAlignment(.center)
Spacer()
Text("1") // Set the same content as left aligned text view
.hidden()
}
.padding(.horizontal)

Not sure if it's the best way, but you can use a GeometryReader to get the screen width and skip the first half.
To place the text exactly in the center, you should also calculate the width of the text. you can use a simple extension to get the size of your text:
extension String {
public func size(withFont font: UIFont) -> CGSize {
(self as NSString).size(withAttributes: [.font: font])
}
}
Here is the example code:
GeometryReader { geo in
HStack {
Spacer()
.frame(width: (geo.size.width - "center".size(withFont: UIFont.systemFont(ofSize: 18)).width) / 2)
HStack {
Text("center")
Text("another")
}
}
}
I want to align the heights of two HStack members. The expected outcome would be that the image has the same size as the text. The current outcome is that the image has more height than the text. This is my current setup:
HStack {
Text("Sample")
.font(.largeTitle)
.padding()
.background(
RoundedRectangle(cornerRadius: 10)
.foregroundColor(.red)
)
Spacer()
Image(systemName: "checkmark.seal.fill")
.resizable()
.scaledToFit()
.padding()
.background(
RoundedRectangle(cornerRadius: 10)
.foregroundColor(.red)
)
}
What I've tried:
.fixedSize() -> I tried to tack this modifier onto the Image but the result was that the Image's height got smaller than the text's. Probably because the SFSymbol's intrinsic height is smaller than the .largeTitle intrinsic height.
AlignmentGuide -> I tried to create a custom alignment guide where I initially thought I could say "align bottom of Image and Text and align top of Image and Text" and therefore have the same height. But it seemed like you can only apply a single alignment guide per stack view.
GeometryReader -> I tried to wrap the HStack in a GeometryReader in which I tacked the .frame(height: proxy.frame.height) view modifier on the Text and Image. This also did not help because it somehow just made some white space around the views.
How it is:
How I want it:
Wrap your Image in a Text. Since your image is from SF Symbols, SwiftUI will scale it to match the dynamic type size. (I'm not sure how it will scale other images.)
VStack {
let background = RoundedRectangle(cornerRadius: 10)
.foregroundColor(.red)
ForEach(Font.TextStyle.allCases, id: \.self) { style in
HStack {
Text("\(style)" as String)
.padding()
.background(background)
Spacer()
Text(Image(systemName: "checkmark.seal.fill"))
.padding()
.background(background)
}
.font(.system(style))
}
}
You can get the size of the Image small by adding a .frame() modifier to your HStack. See the code below,
HStack {
// Some Content
}
.frame(height: 60) // Interchangeable with frame(maxHeight: 60)
The Result:
For your exact example, I found 60 to be the sweet spot. But if you wanted a more dynamic solution, I'd make a few changes to your code. See the code below.
HStack {
Text("Sample")
.font(.largeTitle)
.frame(maxHeight: .infinity) // force the text to take whatever height given to the Parent View, which is the HStack
.padding(.horizontal) // Add padding to the Text to the horizontal axis
.background(
RoundedRectangle(cornerRadius: 10)
.foregroundColor(.red)
)
Spacer()
Image(systemName: "checkmark.seal.fill")
.resizable()
.scaledToFit()
.padding()
.background(
RoundedRectangle(cornerRadius: 10)
.foregroundColor(.red)
)
}
.background(Color.gray)
.frame(height: 100) // Change this value and the embedded Views will fit dynamically
The output will work as shown in the GIF below,
Here is an upgrade version of rob answer which support Assets Image plus system Image! Almost any Image! Like this:
struct ContentView: View {
var body: some View {
VStack {
ForEach(Font.TextStyle.allCases, id: \.self) { style in
HStack {
Text(String(describing: style))
.padding()
.background(Color.pink.opacity(0.5).cornerRadius(10.0))
Spacer()
}
.font(.system(style))
.background(
Image("swiftPunk")
.resizable()
.scaledToFit()
.padding()
.background(Color.yellow.cornerRadius(10.0))
, alignment: .trailing)
}
}
}
}
Result:
I'm new to SwiftUI, so I'm following a tutorial to get familiar with it. However, my app's content is getting cut off on smaller screens (both vertically and horizontally). How can I prevent this from happening?
Here's my code:
EDIT: I have added borders around my images and resized the images as suggested in your comments and answers, but as you can see, the images don't appear to be taking up any more space than they're supposed to.
struct ContentView: View {
var body: some View {
ZStack {
Image("background").ignoresSafeArea(.all)
VStack {
Spacer()
Image("logo")
.resizable()
.aspectRatio(contentMode: .fit)
.frame(width: 100)
.border(Color.black)
Spacer()
HStack {
Spacer()
Image("card3").border(Color.black, width: 3)
Spacer()
Image("card4").border(Color.black, width: 3)
Spacer()
}
Spacer()
Image("dealbutton")
.resizable()
.aspectRatio(contentMode: .fit)
.frame(width: 100)
.border(Color.black)
Spacer()
HStack {
Spacer()
VStack {
Text("Player").padding(.bottom, 10)
Text("0").font(.largeTitle)
}
Spacer()
VStack {
Text("CPU").padding(.bottom, 10)
Text("0").font(.largeTitle)
}
Spacer()
}
.foregroundColor(.white)
Spacer()
}
}
}
}
And here's what the preview looks like on an iPod touch:
Try making Image("background") resizable or set it as the .background(:) of your ZStack. Currently the background image isn’t resizable and is larger than the screen, so it shows at its native size and stretches its parent ZStack beyond the bounds of the screen. Since your content is in that same ZStack, it also extends beyond the bounds of the screen
Your issue is related to your images that you have present on the view structure itself. Images are rendered at 100% their size, irrespective of their constraints. This will cause other views to be pushed away. The solution for that is to set a set size on the view itself that matches within the confines of your available space. Also you're resizing your ZStack which also resizes the content inside of the ZStack. For example.
Image("logo")
.resizeable()
.aspectRatio(contentMode: .fit)
.frame(width: 100)
Handling your image like this will ensure that it is set to the appropriate size when it is rendered. Then you can have the remaining views fall into place in a way that's expected. If you need it scaled on a % for the screen size you can use a GeometryReader to scale the view for different screen sizes.
GeometryReader { reader in
Image("logo")
.resizeable()
.aspectRatio(contentMode: .fit)
.frame(width: reader.size.width * 0.2)
}
Finally, remove your ZStack and set it up like this.
VStack {
//Your Content
}.background(
//Make sure to set the edgesIgnoring.. on this NOT the VStack
Image("background").edgesIgnoringSafeArea(.all)
)
Tip When Working with Stacks
Stacks, wether VStack, HStack, or ZStack's all ALWAYS have their frame set to the content that is held inside of them. If you had an object with a width of 100 and a height of 10,000 then the Stack would also have those dimensions, unless otherwise specified with a Modifier such as .frame(width...) or even, in your case, an Image that is resized.
Suppose your same stack then has a width: 10, height: 10 view added to it, it would still retain the same size as the largest content held within. This is of course handled differently with HStack and VStacks as they actually stack things in a 2D plane, whereas the ZStack works on the 3D plane.
When I click my SwiftUI text field and the keyboard opens, the app zooms out (shown in video).
I have two questions about this behaviour:
Why does this happen?
How do I avoid this happening?
Here is my code:
struct BestillView: View { // This view is put inside a tab view with .ignoresSafeArea
#State var navn = ""
#State var varsling = true
var body: some View {
NavigationView {
ZStack {
Color("BackgroundColor")
.ignoresSafeArea()
VStack {
Image("Liquid") // This is my image overlayed on the background, i suspect this may be the only element that actually gets zoomed out
.resizable()
.aspectRatio(contentMode: .fit)
.ignoresSafeArea()
Spacer()
}
VStack {
ZStack(alignment: .leading) { // This is where the text field i'm having trouble with is
Color("UnselectedColor")
.frame(height: 50)
.cornerRadius(20.0)
if navn.isEmpty { // I have a separate text element as the placeholder text so i can give it a custom color
Text("Navn")
.foregroundColor(Color("AccentColor"))
.padding()
}
TextField("", text: $navn)
.padding()
}
.frame(width: 300)
Spacer()
.frame(height: 20.0)
// I removed the rest of my code, I don't think it should be necessary in this question - it's only a NavigationLink and a Toggle
}
}
}
}
}
You have .ignoresSafeArea() on your Image, but you actually need it on the VStack that contains the Image. The VStack is shrinking to fit the keyboard’s safe area, which squeezes the image too.
The view is actually not shrinking; the image is shrinking - because as the view moves up, it has less height to fit.
You can update your code as:
Image("Liquid")
.aspectRatio(contentMode: .fill)
and it will keep the size same - as the width will remain same.
