My project was using a List but I needed a ScrollView wrapped view so I changed the List to just a ForEach loop with a view and Divider in between. I noticed my Context Menu doesn't look the same as when it was in the List as in the screenshot below.
I'd like the item selected with context menu to look like the List item selected since I can no longer use List in the code, it doesn't look as pretty. Also I have to press on the image and or text to open the Context Menu unlike in a List you can select the row. The end result would be to mimic the style of the selected List item.
/// Context Menu looks terrible
VStack (alignment: .leading, spacing: 0){
ForEach(self.welcome.views.dropLast(), id: \.id) { view in
ForEach(view.views ?? [], id: \.id) { purple in
ForEach(purple.views, id: \.id) { fluffy in
VStack (alignment: .leading, spacing: 0){
if viewClass == "FeaturedHeaderView" {
Text(title)
.font(.title3)
.fontWeight(.bold)
} else {
HStack (spacing: 15){
RequestImage(Url(image), animation: nil)
.aspectRatio(contentMode: .fit)
.frame(width: 60, height: 60)
.clipped()
.cornerRadius(13.5)
VStack (alignment: .leading){
Text(name)
.font(.headline)
.fontWeight(.bold)
Text(author)
.foregroundColor(Color.secondary)
.font(.footnote)
Text(repo)
.foregroundColor(Color.secondary)
.font(.caption)
}
}
.contextMenu(ContextMenu(menuItems: {
HStack {
Button(action: {
openURL(URL(string: "URL")!)
}) {
Label("Open in Safari", systemImage: "safari.fill")
}
}
}))
}
}
Divider()
}
}
}
.padding(.all, 5)
.padding(.leading, 5)
}
/// List Context Menu looks great but can't use List in ScrollView
List {
ForEach(self.welcome.views.dropLast(), id: \.id) { view in
ForEach(view.views ?? [], id: \.id) { purple in
ForEach(purple.views.dropLast(), id: \.id) { fluffy in
VStack (alignment: .leading, spacing: 0){
if viewClass == "FeaturedHeaderView" {
Text(title)
.font(.title3)
.fontWeight(.bold)
} else {
HStack (spacing: 15){

.contextMenu(ContextMenu(menuItems: {
HStack {
Button(action: {
openURL(URL(string: "URL")!)
}) {
Label("Open in Safari", systemImage: "safari.fill")
}
}
}))
}
}
}
}
}
.padding(.all, 10)
.listRowInsets(EdgeInsets())
}
The possible solution is to add background modifier above contextMenu, like
.frame(maxWidth: .infinity) // << to make it screen-wide
.background(
RoundedRectangle(cornerRadius: 12) // << tune as needed
.fill(Color(UIColor.systemBackground)) // << fill with system color
)
.contextMenu(ContextMenu(menuItems: {

I wanted to make a RoundedRectangle that shows all the information and under it, there's a list of data.
The goal was, to make it look like a card, but when I change the background, it leaves a weird white gap, where it doesn't change the color. I already tried to change the background color, foreground color, accent color and everything I know for every single layer but I can't find the problem...
I made the RoundedRectangle .background green in this case, to make it more obvious.
Picture of the app, arrows are edited!
```var body: some View {
NavigationView {
VStack(alignment: .center) {
ZStack {
RoundedRectangle(cornerRadius: 25)
.padding()
.foregroundColor(.white)
.background(Color.green)
.frame(width: nil, height: 250)
VStack {
Text("Verfügbar")
.foregroundColor(.gray)
.italic()
.font(.title2)
Text("\(totalMoneyToday(), specifier: "%.2f")€")
.foregroundColor(.blue)
.bold()
.font(.largeTitle)
HStack {
Spacer()
VStack(alignment: .leading) {
Text("Einkommen")
.foregroundColor(.gray)
.italic()
HStack {
Label("", systemImage: "arrow.up.circle")
.foregroundColor(.green)
Text("\(posMoney(), specifier: "%.2f")€").bold()
}
}
Spacer()
VStack(alignment: .trailing) {
Text("Ausgaben")
.foregroundColor(.gray)
.italic()
HStack {
Label("", systemImage: "arrow.down.circle")
.foregroundColor(.red)
Text("\(negMoney(), specifier: "%.2f")€").bold()

Text(money.name!)
.bold()
Text("\(money.amount, specifier: "%.2f")") + Text("€")
}
Spacer()
Text("\(money.date!, style: .date)")
.foregroundColor(.gray)

Thank you so much guys!
I think it is just default spacing, make it zero
NavigationView {
VStack(alignment: .center, spacing: 0) { << here !!
It's your ZStack background.
var body: some View {
NavigationView {
VStack(alignment: .center) {
ZStack {
RoundedRectangle(cornerRadius: 25)
.padding()
.foregroundColor(.white)
.background(Color.green)

I want to align the two buttons on the bottom of my Text. How can I align an H-stack
container on bottom of a view ??
ZStack{
VStack{
Color.white.ignoresSafeArea()
Text("TAP TO SEE MORE")
.foregroundColor(Color.black)
.font(.system(size: 30))
.bold()
HStack(alignment: .center, spacing: 50, content: {
Button("Admin"){
}
Button("Employee"){
}
})
}
}
I want to have this content in the middle of screen
ZStack{
Color.white.ignoresSafeArea()
VStack{
Text("TAP TO SEE MORE")
.foregroundColor(Color.black)
.font(.system(size: 30))
.bold()
HStack(alignment: .center, spacing: 50, content: {
Button("Admin"){
}
Button("Employee"){
}
})
}
}
This should fix it.
The problem was that you had Color.white.ingoresSafeArea() inside the VStack, which was placing it above the text and buttons instead of behind, which caused the text etc. to be pushed to the bottom.
You have to move Color inside the ZStack instead of VStack:
ZStack {
Color.gray.ignoresSafeArea() // <-- here
VStack{
Text("TAP TO SEE MORE")
.foregroundColor(Color.black)
.font(.system(size: 30))
.bold()
HStack(alignment: .center, spacing: 50) {
Button("Admin") { }
Button("Employee") { }
}
}
}
I'm currently working on trying to implement a custom dropdown menu in SwiftUI that displays a grid of buttons (1-16) and allows you to select one of them. I am using an overlay to display the dropdown below the corresponding button, and it seems to be functioning properly except it's displaying the dropdown below all of the other elements in the view. I found another post here regarding this issue and they used a ZStack to solve it, but I haven't been able to get the same success. Does anyone have any ideas on how to fix this? Here's my code:
struct ContentView: View {
#State var showDropdown = false
#State var selected = 0
var body: some View {
ZStack {
HStack(spacing: 30) {
VStack(alignment: .leading, spacing: 10) {
HStack {
Text("Some Text")
.lineLimit(1)
Spacer()
Button(action: { showDropdown.toggle() }) {
Text(selected == 0 ? "Omni" : String(selected))
.frame(width: 80, height: 36)
}
.zIndex(1)
.overlay(
VStack(spacing: 0) {
if self.showDropdown {
Spacer(minLength: 26)
DropdownMenu(selection: self.$selected)
} else {
EmptyView()
}
}, alignment: .topLeading
)
}
HStack {
Text("Some Text")
.lineLimit(1)
Spacer()
Button(action: { }) {
Text("Omni")
.frame(width: 80, height: 36)
}
}
}
VStack(alignment: .leading, spacing: 10) {
HStack {
Text("Some Text")
.lineLimit(1)
Spacer()
Button(action: { }) {
Text("Omni")
.frame(width: 80, height: 36)
}
}
HStack {
Text("Some Text")
.lineLimit(1)
Spacer()
Button(action: { }) {
Text("Omni")
.frame(width: 80, height: 36)
}
}
}
}
}
.padding()
.frame(maxHeight: .infinity)
.buttonStyle(PlainButtonStyle())
}
}
and here are some images of the results:

Thank you in advance!
The .zIndex works for view in same container, so you need something like the following (or make custom flat layout container with all such buttons at same level, then rise clicked button atop).
VStack(alignment: .leading, spacing: 10) {
HStack {
Text("Some Text")
.lineLimit(1)
Spacer()
Button(action: { showDropdown.toggle() }) {
Text(selected == 0 ? "Omni" : String(selected))
.frame(width: 80, height: 36)
}
.zIndex(1)
.overlay(
VStack(spacing: 0) {
if self.showDropdown {
Spacer(minLength: 26)
DropdownMenu(selection: self.$selected)
}
}, alignment: .topLeading
)
}.zIndex(showDropdown ? 1 : 0) // << this !!
HStack {
Text("Some Text")
.lineLimit(1)
Spacer()
Button(action: { }) {
Text("Omni")
.frame(width: 80, height: 36)
}
}
}.zIndex(showDropdown ? 1 : 0) // << and this !!
I have a login screen and wish to navigate to a new screen when the Login button is clicked.
I did try to wrap the button and the entire screen layout under NavigationView and embedded the button in a Navigation Link.
I am unable to figure out how to show the new screen when the button is clicked. Following is the code for the login screen.
ZStack {
Color.red
.edgesIgnoringSafeArea(.all)
VStack(alignment: .center, spacing: 180.0) {
Text("SwiftUI")
.font(.largeTitle)
.bold()
.padding()
VStack(alignment: .center, spacing: 25) {
TextField("Username", text: $userName)
.padding(.all)
.background(Color.white)
.cornerRadius(10)
TextField("Password", text: $userPassword)
.padding(.all)
.background(Color.white)
.cornerRadius(10)
Toggle(isOn: $isFirstTimeUser) {
Text("First Time User")
.font(.headline)
.bold()
.padding(.horizontal, -10)
.foregroundColor(Color.white)
}.padding(.horizontal, 17)
Button(action: {
if self.userName.count <= 5 {
self.isAlertShown = true
} else {
}
})
{
Text(isFirstTimeUser ? "SignUp" : "Login")
.fontWeight(.medium)
.font(.title)
.foregroundColor(Color.red)
.padding(.horizontal, 10)
}.padding()
.background(Color.white)
.cornerRadius(10)
.alert(isPresented: $isAlertShown) {
() -> Alert in
Alert(title: Text("UserName Invalid"), message: Text("Username has to be more than 5 characters"), dismissButton:.default(Text("Got that!")))
}
}.padding(.horizontal, 17)
}
}
Here is possible approach
1) Add link tag state variable to your View
#State private var current: Int? = nil
2) Wrap your view hierarchy into NavigationView to make possible NavigationLink to work
3) Add tagged NavigationLink above your button
NavigationLink(destination: YourDestinationViewHere(), tag: 1, selection: $current) {
EmptyView()
}
4) Add link tag selection to button action
Button(action: {
if self.userName.count <= 5 {
self.isAlertShown = true
} else {
self.current = 1 // this activates NavigationLink with specified tag
}
})
When I tapped OrderButton, all the VStack's background color is changing to gray color then turning back like assigned a click event. How can I prevent this?
import SwiftUI
struct DrinkDetail : View {
var drink: Drink
var body: some View {
List {
ZStack (alignment: .bottom) {
Image(drink.imageName)
.resizable()
.aspectRatio(contentMode: .fit)
Rectangle()
.frame(height: 80)
.opacity(0.25)
.blur(radius: 10)
HStack {
VStack(alignment: .leading, spacing: 3) {
Text(drink.name)
.foregroundColor(.white)
.font(.largeTitle)
Text("It is just for $5.")
.foregroundColor(.white)
.font(.subheadline)
}
.padding(.leading)
.padding(.bottom)

}
}

struct OrderButton : View {
var body: some View {

}
}
#if DEBUG
struct DrinkDetail_Previews : PreviewProvider {
static var previews: some View {
DrinkDetail(drink: LoadModule.sharedInstance.drinkData[3])
}
}
#endif
The issue resolved by using ScrollView and adding some more parameters for auto resize of Text:
ScrollView(.vertical, showsIndicators: false) {
ZStack (alignment: .bottom) {
Image(drink.imageName)
.resizable()
.aspectRatio(contentMode: .fit)
Rectangle()
.frame(height: 80)
.opacity(0.25)
.blur(radius: 10)
HStack {
VStack(alignment: .leading, spacing: 3) {
Text(drink.name)
.foregroundColor(.white)
.font(.largeTitle)
Text("It is just for $5.")
.foregroundColor(.white)
.font(.subheadline)
}
.padding(.leading)
.padding(.bottom)
Spacer()
}
}
.listRowInsets(EdgeInsets())
VStack(alignment: .leading) {
Text(drink.description)
.foregroundColor(.primary)
.font(.body)
.lineLimit(nil)
.fixedSize(horizontal: false, vertical: true)
.lineSpacing(12)
.padding(Edge.Set.leading, 15)
.padding(Edge.Set.trailing, 15)
HStack {
Spacer()
OrderButton()
Spacer()
}
.padding(.top, 50)
.padding(.bottom, 50)
}
.padding(.top)
}
.edgesIgnoringSafeArea(.top)
.navigationBarHidden(true)
What's the UI you are trying to get? Because, from your example, it seems that List is not necessary. Indeed, List is:
A container that presents rows of data arranged in a single column.
If you don't really need List you can replace it with VStack (if your content must fit the screen) or with a ScrollView (if your content is higher than the screen). Replacing the List will solve your issue that depends on the list selection style of its cells.
An alternative, if you need to use the List view is to set the selection style of the cells in the SceneDelegate to none (but this will affect all of your List in the project) this way:
func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
let contentView = ContentView() //replace this with your view
if let windowScene = scene as? UIWindowScene {
UITableViewCell.appearance().selectionStyle = .none
let window = UIWindow(windowScene: windowScene)
window.rootViewController = UIHostingController(rootView: contentView)
self.window = window
window.makeKeyAndVisible()
}
}
