问题 I didn't find any link or guide to change the "return" key to "done" when keyboard open for TextField in SwiftUI. Is it possible now without customising UITextField? 回答1: The best way I found was to just add the package Introspect to your project. After doing so add in import Introspect anywhere in your project files. Then add one of their View Modifiers to your Textfield to achieve what you want. I believe this is what you want though ⤵ .introspectTextField { textfield in textfield

问题 Using SwiftUI (latest XCode and testing on IOS 13.3) I'm trying to implement a long press gesture on items in a list, to allow user interaction with the individual items. The problem is that when I set "onLongPressGesture" anywhere in the list (on items, on the list itself), the list cannot be scrolled anymore. I can easily get a simple tap to work but a long press blocks scrolling. I've put together a small example that show this issue: struct ContentView: View { let data = [ "Test 1","Test

问题 I know SwiftUI does not support currently regular for loops but instead provide something called ForEach but what is the difference between that and a List? 回答1: ForEach is a view that lets you pass a collection of data to its initializer and then creates multiple "subviews" from the closure you provide. It doesn't have any semantics on how the views will be arranged. Example: ForEach(1...5) { row in Text("Row \(row)") } will create the equivalent off Text("Row 1") Text("Row 2") Text("Row 3")

问题 Is there a way to change the default scrolling animation of the ScrollView by using ScrollViewReader ? Problem I have tried different things but the animation remained as the default one. withAnimation(.easeInOut(duration: 60)) { // <-- Not working (changes nothing) proxy.scrollTo(50, anchor: .center) } As you can see here: (Obviously this is faster than a 1 minute animation) My demo code struct ContentView: View { var body: some View { ScrollView { ScrollViewReader { proxy in Button("Scroll

问题 Since the beta 5 of Xcode 11 launched, I have had to update the code. You know the drill. However, there is this weird runtime error that is surviving the changes, and I cannot figure out why it happens. I started trying to corner it within my original code, but surprisingly it also happens in the simplest test project that I managed to come up with: a TabView with a table. The procedure to have the Xs simulator crash with SIGABRT while changing to another tab in runtime with the error:

问题 how can I add a border with a cornerRadius to an Image. I get a deprecation warning saying that i should use a RoundedRectange Shape, but i don't know how to use that exactly Beta 4: Image(uiImage: ...) .border(Color.black, width: 2, cornerRadius: 10) 回答1: SwiftUI 1.0 Using cornerRadius & overlay Modifiers Here is another way in which we can use a cornerRadius modifier (which clips the view) and then overlay a stroke with a color. VStack(spacing: 40) { Text("Image Border").font(.largeTitle)
