问题 Is it possible to adjust the spacing between section blocks in a form? Ive tried using .padding() but it only moves whatever is inside the section, not the actual section itself. 回答1: Try a spacer between the sections: Spacer(minLength: CGFloat?) 回答2: You can try this property without giving float value too Spacer() // this will work 来源： https://stackoverflow.com/questions/60143989/spacing-between-sections-in-a-form

问题 I have an array of elements, from which I want to chose one using Picker , and I have a Button which simply adds a new element to the array. The thing is, when I add an element, the Picker choices are not updated. It doesn't work with DefaultPickerStyle , but works with SegmentedPickerStyle . The code: import SwiftUI struct ExampleView: View { @State var array : Array<Int> = [Int]() @State var selection : Int = 0 var body: some View { VStack { Picker("", selection: self.$selection) { ForEach

问题 I'm using WKWebView in a SwiftUI app. I have an HTML file in my bundle that I'm initially loading into the WKWebView. The file has a link in it that I would like to open in an external browser if tapped. I've created the WKWebView using the following code: import SwiftUI import WebKit struct WebView: UIViewRepresentable { typealias UIViewType = WKWebView let request: URLRequest func makeUIView(context: UIViewRepresentableContext<WebView>) -> WKWebView { let webView = WKWebView() let delegate

问题 I wanted to ask if following scenario would be possible and if yes how I could approach the problem. The following code produces the attached image: HStack(alignment: .firstTextBaseline) { ZStack { RoundedRectangle(cornerRadius: 5) .foregroundColor(Color(UIColor.secondarySystemFill)) Text("Test") .clipShape(RoundedRectangle(cornerRadius: 5)) .foregroundColor(.secondary) .layoutPriority(1) .padding(.all, 5) } Text("This is a very long message with more words than one line can handle bla blabla

问题 I need to dynamically present views based on a model so the decision of which view to present and the creation of the views needs to be external to the SwiftUI views. This is working well on iOS 13 but on iOS 14 the first view presents again instead of the second view, although the second view does get initialised as expected the first view is pushed onto the navigation stack a second time. It seems like a iOS 14 bug but perhaps I'm doing something wrong so asking here before filing a bug

问题 I have an array of items (numbers) to be presented to the user using NavigationView, List and a leaf page. When I update an item (numbers[index] = ...) on a leaf page, it updates the list correctly (which I see when I go back to the list), but not the leaf page itself immediately. I see the change if I go back to the list and re-open the same leaf page. I would like to understand why it does not update the UI immediately, and how to fix it. Here is the simplified code to re-produce this
