I want to show custom drop down menu very attractive view but it does not work when I write the code as I want.
This is drop down menu approach but does not work can anyone tell the solution in any others way also.
struct DropDownList:View{
var body: some View{
Menu(content: {
HStack{
Image(systemName: "eye")
Text("Eye Clinic")
}
HStack{
Image("neuro")
Text("Neuro Hospital")
}
}, label: {
Text("Hospitals")
})
}
}
Your question isn't clear, but the menu you show in the image can be created as follows:
struct ContentView: View {
var body: some View {
HStack {
Text("Something")
DropDownList()
}
}
}
struct DropDownList:View {
var body: some View {
Menu {
Button {
} label: {
Label("Edit", systemImage: "square.and.pencil")
}
Button {
} label: {
Label("Delete", systemImage: "trash")
}
} label: {
Image(systemName: "ellipsis")
}
}
}

withAnimation {
isShowingRed.toggle()

struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView()
}
}
but got error like ;
An unknown crash has occurred, check back for more information. How to fix that erro,any idea?
Thanks.
It looks like you forgot to put a . before transition(.asymmetric(insertion: .scale, removal: .opacity)).
That might be why.

I already have an animation made in AfterEffects that I think Lottie can turn into a format I can use for my app. What I am wondering is how can I make the app start performing this animation when it is opened until the app is done loading?
Simply show the animation view instead of your content view while it's loading
example:
struct ContentView: View {
#State var isLoading = true
var body: some View {
VStack {
if isLoading {
LoadingView()
} else {
DoneLoadingView()
}
}.onAppear {
DispatchQueue.main.asyncAfter(deadline: .now() + 2) {
isLoading = false
}
}
}
}
struct LoadingView: View {
var body: some View {
ProgressView()
}
}
struct DoneLoadingView: View {
var body: some View {
VStack {
Text("Hello, world!")
}
}
}

The screen transitions with NavigationLink.
I want to return to the first screen by clicking the button on the third screen.
How do you do it?
The following code returns from the third screen to the second screen.
struct FirstView: View {
var body: some View {
VStack {
NavigationView {
NavigationLink(
destination: SecondView()
) {
Text("next")
}
}
}
}
}
struct ThirdView: View {
#Environment(\.presentationMode) var presentationMode: Binding<PresentationMode>
var body: some View {
VStack {
Button(action: {
self.presentationMode.wrappedValue.dismiss()
}) {
Text("next")
}
}
.navigationBarTitle("Third", displayMode: .inline)
}
}
I had encountered this problem, too.
But I solved it already.
Here is the solution.
Maybe it can work.

how can I add a Button in SwiftUI below a List so that it looks like in the Note app:
I tried it with a Stack but this did not work.
Here is simple demo:
struct DemoListWithButton: View {
var body: some View {
NavigationView {
VStack(alignment: .trailing) {
List(0..<100) { i in
Text("Item \(i)")
}
.navigationBarTitle("Title")
Button("Button") {}
.padding()
}
}
}
}
struct DemoListWithButton_Previews: PreviewProvider {
static var previews: some View {
DemoListWithButton()
}
}

I am setting NavigationLink for Item,but not work with image disappeared.
struct Items: View {
var landmarks: [Landmark]
var body: some View {
ScrollView(.horizontal, showsIndicators: false) {
HStack {
ForEach(landmarks) { landmark in
//加了这个导航就看不到图片了，CategoryHome 也不显示图片，
//NavigationLink(destination: LandmarkDetail(landmark: landmark)) {
Item(landmark: landmark)
//}
}
}
}
}
}
You have to embed your Scrollview into a NavigationView or it will not work
struct Items: View {
var landmarks: [Landmark]
var body: some View {
NavigationView {
ScrollView(.horizontal, showsIndicators: false) {
HStack {
ForEach(landmarks) { landmark in
//加了这个导航就看不到图片了，CategoryHome 也不显示图片，
NavigationLink(destination: LandmarkDetail(landmark: landmark)) {
Item(landmark: landmark)
}
}
}
}
}
}
}
