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)
}
}

Does anyone know how to make the following view in SwiftUI?
HStack:
[ blank logo(centered) Skip(text)]
So I have the following HStack:
Zstack(alignment: .topLeading) {
VStack{
HStack {
Image("onboarding-logo")
.resizable()
.scaledToFit()
.frame(width: 150.0, height: 150.0)
.padding(.top, 35)
}
}
}
Does anyone know how I can have a "Skip" text in the top right corner of the screen, but also keep my logo centered and not have anything on the left side? I've tried Spacers and all, but I'm having no luck.
I would like to click "Skip" and then lead to another view.
There are many ways to achieve this. Here I have used LazyVGrid since other answers based on Stacks
struct ContentView: View {
var body: some View {
VStack {
LazyVGrid(columns: [GridItem(), GridItem(), GridItem()], content: {
Spacer()
Image(systemName: "star.fill")
.frame(width: 150, height: 150, alignment: .center)
.border(.gray)
Button(action: {
}, label: {
Text("Skip")
})
})
.border(.gray)
Spacer()
}
}
}
Is this the screen configuration you want?
The Zstack is used to center the Hstack into which the image is placed, and the new HStack uses a spacer to move the Text to the right.
import SwiftUI
struct ContentView: View {
var body: some View {
ZStack {
VStack {
HStack(alignment: .center) {
Image("farnsworth")
.resizable()
.scaledToFit()
.frame(width: 150.0, height: 150.0)
}
Spacer()
}
VStack {
HStack {
Spacer()
Button {
// do Something...
} label: {
Text("Skip>>")
.padding(.top, 10)
}
}
Spacer()
}
}
.padding()
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView()
}
}
I'm trying to use my custom card view as label to navigation link. this navigation link is also a Grid item.
The result is a
My Card Code:
struct CityCard: View {
var cityData: CityData
var body: some View {
VStack {
Text("\(cityData.name)")
.padding([.top], 10)
Spacer()
Image(systemName: cityData.forecastIcon)
.resizable()
.frame(width: 45, height: 45)
Spacer()
HStack(alignment: .bottom) {
Text(String(format: "%.2f $", cityData.rate))
.padding([.leading, .bottom], 10)
Spacer()
Text(String(format: "%.2f °", cityData.degrees))
.padding([.trailing, .bottom], 10)
}
}.frame(width: 150, height: 150)
.background(Color.blue)
.cornerRadius(10)
.navigationTitle(cityData.name)
}
}
My List View:
struct CityList: View {
var cities: [CityData]
let columns = [
GridItem(.flexible(minimum: 150, maximum: 150)),
GridItem(.flexible(minimum: 150, maximum: 150))
]
var body: some View {
ScrollView {
LazyVGrid(columns: columns, spacing: 20) {
ForEach(self.cities) { item in
NavigationLink(destination: Text(item.name), label: {
CityCard(cityData: item)
})
}
}
}
}
}
someone has a solution why it gives me this opacity?
Update:
The main contact view is:
It's greyed out because you don't yet have a NavigationView in your view hierarchy, which makes it possible to actually navigate to a new view.
You can, for example, wrap your ScrollView in a NavigationView:
var body: some View {
NavigationView {
ScrollView {
LazyVGrid(columns: columns, spacing: 20) {
ForEach(self.cities) { item in
NavigationLink(destination: Text(item.name), label: {
CityCard(cityData: item)
})
}
}
}
}
}
Or, if it's only happening in your preview, add a NavigationView to your preview code:
NavigationView {
CityList(...)
}
Keep in mind that if you have the default accent color (blue, in light mode) that your links will become invisible (since they will be blue) on top of the blue background. You can set a custom accent color in your project or via the accentColor modifier:
NavigationView {
//content
}.accentColor(.black)
I'm trying to create a scroll view with my custom view, but when I add scroll to view it's not working as expected, without scroll view working fine.
struct ContentView: View {
var body: some View {
ScrollView(.vertical) {
VStack {
ForEach (0..<2) { _ in
ListItem()
}
}
}
}
}
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView()
}
}
// But the below code is working fine.
struct ContentView: View {
var body: some View {
VStack {
ForEach (0..<2) { _ in
ListItem()
}
}
}
}
// List Item
struct ListItem: View {
var body: some View {
VStack {
HStack {
Image("steve")
.resizable()
.clipShape(Circle())
.aspectRatio(contentMode: .fit)
.frame(maxWidth:44, maxHeight: 44)
VStack {
Text("Steve Jobs")
.font(.headline)
.frame(maxWidth: .infinity, alignment: .leading)
Text("1 hour ago")
.font(.footnote)
.frame(maxWidth: .infinity, alignment: .leading)
}
Spacer()
}
ZStack(alignment:.top) {
GeometryReader { geometry in
VStack {
ZStack {
Image("poster_1")
.resizable()
.aspectRatio(contentMode: .fit)
.cornerRadius(8)
.shadow(color: Color.black.opacity(0.12),
radius: 4, x: 1, y: 1)
.frame(width: geometry.size.width - 64,
height: geometry.size.height * 0.35)
.padding([.horizontal], 32)
.clipped()
ZStack {
Rectangle()
.fill(Color.black.opacity(0.75))
.frame(maxWidth:84 , maxHeight: 84)
.cornerRadius(12)
Image(systemName: "play.fill")
.font(.system(size: 44, weight: .bold))
.foregroundColor(.white)
}
}
VStack {
Text("Game of Thrones")
.accentColor(Color.gray.opacity(0.25))
.font(Font.subheadline.weight(.bold))
.padding([.horizontal], 32)
.padding([.bottom], 2)
.frame(maxWidth: .infinity,
alignment: .leading)
VStack {
Text("Game of Thrones is an American fantasy drama television series created by David Benioff and D. B. Weiss for HBO. ")
.accentColor(Color.gray.opacity(0.25))
.font(.footnote)
.frame(maxWidth: .infinity,
alignment: .leading)
.padding([.horizontal], 32)
Text("Show more...")
.accentColor(Color.gray.opacity(0.01))
.font(Font.footnote.weight(.bold))
.frame(maxWidth: .infinity,
alignment: .trailing)
.padding([.trailing], 32).onTapGesture {
print("okay")
}
}
}
}
}
}
}
}
}
ListItem contains multiple views which creates publisher info and movie information as shown below image.
Scrollview is scrolling but images are not shown in view as first image.
It is the geometry reader that you have in ListItem. Because neither a GeometryReader nor a Scrollview have their own size. Since neither no what size to render, they collapse. This is what you are seeing in your view. See this answer. The solution is to put the GeometryReader into ContentView outside the Scrollview and send the GeometryProxy that you called geometry into ListItem something like this:
struct ContentView: View {
var body: some View {
GeometryReader { geometry in
ScrollView(.vertical) {
VStack {
ForEach (0..<2) { _ in
ListItem(geometry: geometry)
}
}
} // Scrollview
} // GeometryReader
}
}
struct ListItem: View {
let geometry: GeometryProxy
var body: some View {
...
}
This seems to fix it in Preview, though you may have to change your multipliers in the .frame() that uses geometry to size it how you want.
I have a simple Rectangle which I put a VStack of Numbers in background of that, you can see it in code and pic! the problem is the VStack is taller than Rectangle there for it goes outside of Rectangle, I want the extra part be hidden, How could I solve it?
struct ContentView: View {
let arrayOfHours: [Int] = Array(0...23)
var body: some View {
Rectangle()
.fill(Color.black.opacity(0.25))
.frame(height: 200, alignment: .center)
.padding()
.background(
VStack(alignment: .center, spacing: 4) {
ForEach (arrayOfHours.indices, id: \.self) { index in
Text(arrayOfHours[index].description)
.font(Font.body.bold())
}
}
.background(Color.yellow)
)
}
}
If I understood your description correctly you need clipped, like
struct ContentView: View {
let arrayOfHours: [Int] = Array(0...23)
var body: some View {
Rectangle()
.fill(Color.black.opacity(0.25))
.frame(height: 200, alignment: .center)
.background(
VStack(alignment: .center, spacing: 4) {
ForEach (arrayOfHours.indices, id: \.self) { index in
Text(arrayOfHours[index].description)
.font(Font.body.bold())
}
}
.background(Color.yellow)
)
.clipped() // << here !!
.padding() // should be moved here !!
}
}
I want move the HStack in bottom of my screen no use the spacer() because when use the spacer move the logo for top of my screen.
Here is a solution without using Spacer:
struct ContentView: View {
var body: some View {
VStack {
VStack {
Text("Image")
Text("Some text")
}.frame(minHeight: 0, maxHeight: .infinity)
HStack {
Text("Bottom")
}
}
}
}
I know you asked for no spacer, but this code shows you can use them without your logo going to the top of the screen. Alternatively you can use ".position(CGPoint(...))"
struct ContentView: View {
var body: some View {
VStack {
Spacer()
VStack (alignment: .center) {
Image("your-image").resizable().frame(width: 90, height: 95)
Text("TCheck time").font(.title).foregroundColor(.gray)
}.padding()
Spacer()
HStack (alignment: .bottom) {
Text("2020 SplitWay").font(.subheadline).foregroundColor(.gray)
}
}
}
}
