I can't find a solution to change my background color view, I tried a lot of options and nothing works.
I'm trying solutions but the isn't changing
There is my struct of the code:
struct ContentView: View {
var body: some View {
VStack {
Text("Trying ColorView")
.font(.largeTitle)
.bold()
Button("ColorView") {
}
}
.accentColor(Color.black)
}
}
First of all you have already mistakes in your posted code above, your XCode should normally tell you that.
Which view you want to change..?
This might be a solution... You can change it like you need it.
struct testViewTwo: View {
var body: some View {
NavigationView {
VStack {
VStack(spacing: -15) {
HStack {
HStack {
Text("Hello World")
}.background(Color.blue)
}.foregroundColor(Color.white)
}
}.background(Image("Background"))
}
}
}
You change a background color with the background modifier.
If you want to change the background color of the whole view, you should create a ZStack that spans the whole view with a background modifier.
ZStack {
...
}
.frame(minWidth: 0, maxWidth: .infinity, minHeight: 0, maxHeight: .infinity)
.background(Color(.blue)
You can simply use Color("Green") to change the color. Here's a sample.
var body: some View {
NavigationView{
VStack {
VStack(spacing: 15){
HStack {
Color("Green")
.edgesIgnoringSafeArea(.top)
}
}
}
}
}

I have two simple ui components a Rectangle and an Image.
I just want a slide animation for Rectangle and scale animation for Image.
However, I got a default value animation for both of these.
Is there a problem in my code? I don't have any error. I'm using beta SF Symbols tho. Could this be the problem?
import SwiftUI
struct ContentView: View {
#State var animate: Bool = false
var body: some View {
VStack(alignment: .center) {
HStack() {
if animate {
ZStack() {
Rectangle()
.frame(height: 50)
.transition(.slide)
Image(systemName: "figure.mixed.cardio")
.foregroundColor(.white)
.transition(.scale)
}
}
}
Button("animate") {
withAnimation {
animate.toggle()
}
}
}
}
}
Transition works when specific view appeared, but in your code ZStack loads views and then appears as a whole.
Here is a fix:
HStack() {
ZStack() {
if animate { // << here !!
Rectangle()
.frame(height: 50)
.transition(.slide)
Image(systemName: "figure.mixed.cardio")
.foregroundColor(.white)
.transition(.scale)
}
}
}
The problem here is neither your SF Symbols or Compiling Error.
Animation is a bit tricky especially if you want different animations for different views inside the same stack.
To achieve your goal, you need to wrap each sub view inside an independent stack, then they will have their own unique animation.
Try this code:
import SwiftUI
struct TestView: View {
#State var animate: Bool = false
var body: some View {
VStack(alignment: .center) {
HStack() {
ZStack() {
//added
if animate {
ZStack {
Rectangle()
.frame(height: 50)
} .transition(.slide)
}
//added
if animate {
ZStack {
Image(systemName: "figure.mixed.cardio")
.foregroundColor(.white)
}.transition(.scale)
}
}
}
Button("animate") {
withAnimation {
animate.toggle()
}
}
}
}
}
What I did to make the entire screen black is to use this construction in my view:
ZStack {
Color.black.ignoresSafeArea() }
And for the List modifiers I used the following two:
.listRowBackground(Color.black)
.listStyle(.plain)
This works great.
But then I want to add a view on top of my List (like a header) and some white space appears around it ? Where does that come from ? And how can I change it to black ?
Here is my complete code:
struct WorkoutView: View {
var body: some View {
ZStack {
Color.black.ignoresSafeArea()
List {
TempView()
ForEach(1..<30) { index in
VStack(alignment: .leading, spacing: 4) {
Text("one line")
.foregroundColor(.white)
.font(.title)
.fontWeight(.bold)
}
.padding(.vertical)
}
.listRowBackground(Color.black)
}
.listStyle(.plain)
}
}
}
struct TempView: View {
var body: some View {
ZStack(alignment: .leading) {
Color.black.ignoresSafeArea()
Text("Hello World")
.foregroundColor(.red)
.font(.largeTitle)
.bold()
}
}
}
Just do the same thing you did for the ForEach: add a .listBackground() modifier. Like this:
TempView()
.listRowBackground(Color.black)
I want to create a simple NavigationView. But with code outside of it. Like this:
struct TestView: View {
var body: some View {
VStack{
RoundedRectangle(cornerRadius: 10)
.frame(width: 100, height: 100)
NavigationView {
VStack{
NavigationLink {
Text("HEllo")
} label: {
Text("Click me")
}
.navigationViewStyle(.columns)
}
.navigationTitle("A Title")
}
}
}
}
I do that so the navigation Title is below the item outside the NavigationView.
This code gives me this:
Image because I am not allowed to insert images yet.
When I click on the NavigationLink though I see this:
The Image
As you see the RoundedRectangle still is viewable at top of the screen. How can I fix that, so that the Rectangle disappears and the Destination is viewable in full screen?
Set navigation view first, You have to put everything inside the navigation view.
NavigationView { // Here
VStack{
RoundedRectangle(cornerRadius: 10)
.frame(width: 100, height: 100)
VStack{ // Remove from above
The RoundedRectangle is still visible because it is outside of the NavigationView, only the content of the NavigationView will move with the NavigationLink
Something you could do is to use the toolbar of the NavigationView to place items on the top of the screen
struct TestView: View {
var body: some View {
NavigationView {
NavigationLink {
Text("HEllo")
} label: {
Text("Click me")
}
.navigationViewStyle(.columns)
.navigationTitle("A Title")
.toolbar {
ToolbarItem {
RoundedRectangle(cornerRadius: 10)
.frame(width: 100, height: 100)
}
}
}
}
}
I'm quite new to programming so please excuse any dumb questions. I'm trying to make a ScrollView with the content being buttons. Although the button prints to console, when shown in the simulator the button displays as a large blue rectangle rather than displaying the image I would like it to.
Code Regarding ScrollView:
struct ContentView: View {
var body: some View {
[Simulator Display][1]
VStack {
Image("logo")
.resizable()
.aspectRatio(contentMode: .fit)
.padding(.leading, 50)
.padding(.trailing, 50)
.padding(.top, 20)
.padding(.bottom, -20)
Spacer()
ScrollView {
VStack(spacing: 20) {
Button(action: {
//ToDo
print("Executed")
}) {
Image("Logo")
}
}
}
}
}
}
Simulator Display:
Image(Placeholder for now) I want to be displayed:
So I tried it an yeah it was very weird. Anyway, here is an example of how you can include the image. Just take the portion of the Button and paste it
struct ContentView: View {
var body: some View {
ZStack {
Button(action: {
print("button pressed")
}) {
Image("image")
.renderingMode(.original)
}
}
}
}
I'm attempting to create a master/detail view on macOS with SwiftUI. When the master/detail view first renders, I'd like it to immediately "highlight" / "navigate to" its first entry.
In other words, I'd like to immediately render the following: master/detail first row highlighted
I'm using NavigationView and NavigationLink on macOS to render the master/detail view:
struct ContentView: View {
var body: some View {
NavigationView {
List {
NavigationLink(destination: Text("detail-1").frame(maxWidth: .infinity, maxHeight: .infinity)) {
Text("link-1")
}
NavigationLink(destination: Text("detail-2").frame(maxWidth: .infinity, maxHeight: .infinity)) {
Text("link-2")
}
}
}
}
}
I've tried using both the isActive and the tag / selection options provided by NavigationLink with no luck. What might I be missing here? Is there a way to force focus on the first master/detail element using SwiftUI?
I came across this problem recently and after being stuck at the same point I found Apple's tutorial which shows that you don't use NavigationLink on macOS.
Instead you just create a NavigationView with a List and a DetailView. Then you can bind the List's selection and it works properly.
There still seems to be a bug with the highlight. The workaround is setting the selection in the next run loop after the NavigationView has appeared. :/
Here's a complete example:
enum DetailContent: Int, CaseIterable, Hashable {
case first, second, third
}
extension DetailContent: Identifiable {
var id: Int { rawValue }
}
struct DetailView: View {
#Binding var content: DetailContent?
var body: some View {
VStack {
Text("\(content?.rawValue ?? -1)")
}
.frame(maxWidth: .infinity, maxHeight: .infinity)
}
}
struct MainView: View {
#State var detailContent: DetailContent?
var body: some View {
NavigationView {
List(selection: $detailContent) {
Section(header: Text("Section")) {
ForEach(DetailContent.allCases) { item in
Text("\(item.rawValue)")
.tag(item)
}
}
}
.frame(minWidth: 250, maxWidth: 350)
.listStyle(SidebarListStyle())
if detailContent != nil {
DetailView(content: $detailContent)
}
}
.frame(maxWidth: .infinity, maxHeight: .infinity)
.onAppear {
DispatchQueue.main.async {
self.detailContent = DetailContent.allCases.randomElement()
}
}
}
}
