问题 So, I already read several blogs, posts, and Apple's own Human Interface Guidelines that iOS 14 Widgets are NOT interactive, BUT: It's possible to pass a short link to the app when pressing on a target. Apple on its own says: "Small Widgets got one single tap target, Medium and Large Widgets got multiple tap targets". OK! Now when you tap on these Targets the app is opening and the Widget is passing that short link to the App. BUT, now my question, where Google says Idk: Can I

问题 I can't find the answer to this anywhere, hopefully one of you can help me out. I have a MainView with some content. And with the press of a button I want to open a DetailView. I am using a ZStack to layer the DetailView on the top, filling the screen. But with the following code I can't get it to work. The DetailView does not have a transition when it inserts and it stops at removal. I have tried with and without setting the zIndex manually, and a custom assymetricalTransition. Couldn't get

问题 I want display or hide items by scroll direction just like safari. Hide something when scroll up, and show it when scroll down. 回答1: You would use GeometryReader to get the global position of one in the views in the ScrollView to detect the scroll direction. The code below will print out the current midY position. Dependent on the +/- value you could display or hide other views. struct ContentView: View { var body: some View { ScrollView{ GeometryReader { geometry in Text("Top View \(geometry

问题 I wan't to display a SwiftUI View as fullscreen in watchOS (without the Cancel/Back Button or Clock) I've tried adding a Sprite Kit Scene to the view and also setting the .edgesIgnoringSafeArea(.all) but I'm still able to hide them or put a view under the top bar. 回答1: Unless it's a game, it's not possible to strip out the space at the top, watchOS reserves it so that the time is always visible to the user. 回答2: Turns out it does "work", even with SwiftUI: Using Interface Builder: https:/
