问题 I am extending my iOS game for tvOS. Most of the game controls are handled by touchesBegan , touchesMoved and touchesEnded . All my select buttons are handled in the following way: if button1.contains(location){ let gameplayScene = GamePlayScene(size: self.size) self.view?.presentScene(gameplayScene) } if button2.contains(location){ let settingsScene = SettingsScene(size: self.size) self.view?.presentScene(settingsScene) } if button3.contains(location){ let helpScene = HelpScene(size: self

问题 I try to loop a video in a TV OS app with the AVPlayerLooper because this should get rid of the pause/hicup when playing the video again. I watched the WWDC2016 video https://developer.apple.com/videos/play/wwdc2016/503/ and try to implement the code but it doesn't loop. I have one PlayerViewController which inherits AVPlayerViewController . I put the code to let the video loop. If I have the following code, it shows nothing. If I change the second line to self.queuePlayer = AVQueuePlayer

问题 Does anybody know how to detect a forced touch/click on the remote control with tvOS? I want to use the click in a Sprite Kit scene to open a 'game paused alert'. I have no UIKit controls which have the focus and will react on the click. I'm already using the 'normal' touch events on the remote control to move my sprites around. 回答1: Apple suggests using UIPressesEvent 's to detect presses/clicks. override func pressesBegan(presses: Set<UIPress>, withEvent event: UIPressesEvent?) { for item

问题 A Note For Readers: This is a long question, but it needs a background to understand the question asked. The color quantization technique is commonly used to get the dominant colors of an image. One of the well-known libraries that do color quantization is Leptonica through the Modified Median Cut Quantization (MMCQ) and octree quantization (OQ) Github's Color-thief by @lokesh is a very simple implementation in JavaScript of the MMCQ algorithm: var colorThief = new ColorThief(); colorThief

问题 Is there any way to change background color of page control in tvOS ?

问题 tvOS 12 has a new framework TVUIKit, which introduces the lockup views. The class I am interested in is TVPosterView, which is basically designed as such: Swift 4.2 open class TVPosterView : TVLockupView { // One may use UIControl to implement it in iOS public init(image: UIImage?) open var image: UIImage? // default is nil open var title: String? open var subtitle: String? } In my storyboard I have added an UIView element, and rightly (at least I hope so. Yesterday the IB agent kept crashing

问题 Editing UITextField in tvOS shows a new view where the user can enter in text, and when text entry is done, the user is returned to the previous view. However, I have found that when I return from the text editor, the text I edit does not show up in my text fields. What's going on? tvOS version 9.1 回答1: The reason why it isn't working is because the UITextField is using a non-default background color. Apparently in tvOS, the background color is rendered to the layer after the text has been

问题 I have a UITextView in my TV app, when i try to make it focusable then the UI is not making it focusable and i am unable to scroll it. I read some questions about it and some says that its a known issue and we should use storyboards. Actually i am using storyboards but still unable to get this to work.

问题 I started a blank tvOS project and created the following code: - (void)viewDidLoad { [super viewDidLoad]; AVPlayer *avPlayer = [AVPlayer playerWithURL:[NSURL URLWithString:@"http://www.myurl.com/myvideo.mp4"]]; AVPlayerLayer *avPlayerLayer = [AVPlayerLayer playerLayerWithPlayer:avPlayer]; avPlayerLayer.frame = CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height); [self.view.layer addSublayer:avPlayerLayer]; [avPlayer play]; } Nothing happens in the simulator though once
