问题 I'm totally perplexed and unable find documentation on how to wrap a UIKit component and have it be sized correctly. Here's the simplest example, wrapping a UILabel: public struct SwiftUIText: UIViewRepresentable { @Binding public var text: String public init(text: Binding<String>) { self._text = text } public func makeUIView(context: Context) -> UILabel { UILabel(frame: .zero) } public func updateUIView(_ textField: UILabel, context: Context) { textField.text = text textField.textColor =

问题 I'm trying to implement such component TextField (5 000) and Text (PLN) together should be centered horizontally. On entering new digit's, Text (PLN) should be dismissed. I think I have to combine this two views in to one container and center in, something like HStack { TextField() Text("PLN") } .frame(alignment: .center) But TextField is taking all possible width. How could I handle it, or probably another solution. 回答1: Here is possible approach with dynamically sized TextField . Note:

问题 I have a list styled with SidebarListStyle (new in iOS 14) inside a NavigationView . struct ContentView: View { let data = ["One", "Two", "Three", "Four", "Five", "Six", "Seven", "Eight", "Nine", "Ten", "Eleven", "Twelve", "Thirteen", "Fourteen"] var body: some View { NavigationView { List { Section(header: Text("Section")) { ForEach(data, id: \.self) { word in Text(word) } } } .listStyle(SidebarListStyle()) .navigationBarTitle(Text("Title"), displayMode: .large) } } } The problem is that

问题 Anybody see problems with @State variables not updating in SwiftUI 2 in Xcode 12b? The problem code is in the contextMenu buttons. The showSheet var is toggled to true but the sheetItem value is not changed. This same code worked in SwiftUI 1. I have filed a Feedback, but was wondering if anyone else has seen this problem. Full code: struct ConnectionsView: View { @EnvironmentObject var connectionViewModel : FileDataViewModel<Connection> @State private var editMode = EditMode.inactive @State

问题 Whenever I rotate the device to landscape and back again, the top of the NavigationView (including the title and back button) get clipped under the status bar. Edit: Minimal reproducible example: struct ContentView: View { var body: some View { NavigationView { ScrollView { VStack { ForEach(0..<15) { _ in Text("Filler") .frame(maxWidth: .infinity) .background(Color.green) .padding() } } } .navigationBarTitle("Data") } } } As long as the content is scrollable, the glitch happens. I originally

问题 My App uses GeometryReader with some padding to setup a View frame dimension inside a NavigationView. Since iOS 14 i get the following error message: Invalid frame dimension (negative or non-finite) Here is some example code to test: import SwiftUI struct ContentView: View { let padding:CGFloat = 16.0 var body: some View { NavigationView { GeometryReader { p in Text("Hello, world!") .frame(width: p.size.width - padding) .padding() } } } } struct ContentView_Previews: PreviewProvider { static

问题 I’m trying to get my views to animate/transition using .transition() on views. I use similar code from here and put .transition() to both conditional views. struct Base: View { @State private var isSignedIn = false var body: some View { Group { if(isSignedIn){ Home().transition(.slide) }else{ AuthSignin(isSignedIn: self.$isSignedIn).transition(.slide) } } } } struct AuthSignin: View { @Binding var isSignedIn: Bool var body: some View { VStack { Button(action: { self.isSignedIn = true }) {
