问题 I want to know if there's a way to enable horizontal scrolling of text i.e., marquee type text. I have used this library: https://github.com/cbpowell/MarqueeLabel-Swift and added the "MarqueeLabel.Swift" file to my application. But so far, it doesn't show the marquee effect that I wanted. This is how I implemented it: class ViewController: UIViewController { @IBOutlet weak var marqueeLabel: MarqueeLabel! override func viewDidLoad() { super.viewDidLoad() self.marqueeLabel.tag = 101 self

问题 I am trying to change the color of a SwiftUI Button on tvOS. Modifying the background almost works, except that you can see that the underlying UIButton is actually using a rounded, translucent image over the top of the background. This results in a different colour at the corners where the rectangular background lies outside the rounded image. Adding .padding emphasises this issue: struct ContentView: View { @State var selected = false var body: some View { Button(action: { self.selected

问题 Check the image below. I need to highlight the focused cell such that it is above all the cells in collectionView . I know I have to change the zIndex of the focused cell. How to do that?

问题 I have a static fat library, which contains the architecture arm64, that can be linked in a project for iOS. However, when I try to use this library in a tvOS project I have the following link error: "... building for tvOS, but linking in object file built for iOS, for architecture arm64" I am not sure if I can reuse arm64 libraries, which work properly in iOS projects, in a tvOS project or perhaps I will have to create an arm64 library from a tvOS project (TV static library). 回答1: For Xcode

问题 I have several AVPlayerViewControllers set as the ViewControllers of a UITabBarController . What I want is having the video of the currently visible AVPlayerViewController automatically pause playing when the user switches to another tab (which is another AVPlayerViewController ) I tried this approach: override func viewWillDisappear(animated: Bool) { player?.pause() super.viewWillDisappear(animated) } but the video just keeps running in the background. (audio is still running at least)
