tvos

问题 I'd like to have a sleep timer within my own tvos app. Is there a way to enable/disable sleeping on tvos? I know you disable sleeping using: [UIApplication sharedApplication].idleTimerDisabled = YES; But is there a way to then enable sleep right away when a timer finishes? 来源： https://stackoverflow.com/questions/33639783/programmatically-sleep-apple-tv-on-tvos

问题 I would like to use AVSpeechSynthesizer to output sound on only one audio channel of a multi-channel surround sound setup. For example, in a 5.1 system, I would like it to output on just the right-surround channel. Right now I have: let synthesizer = AVSpeechSynthesizer() let utterance = AVSpeechUtterance(string: "This is the right channel") synthesizer.speakUtterance(utterance) ...however it outputs on both the left and right channels. 来源： https://stackoverflow.com/questions/32558183/any-way

问题 I have a Sprite Kit game that is crashing when the game is over. This happening on the tvOS 9.1 and iOS 9.2. Before, I had it running on iOS 9.1 without crashing. It seems to be an OpenGL issue, but when I search the function in Xcode, it doesn't come up with anything. Unfortunately, the error is not consistent in appearing in the console. Here's the error: Jet: draw_indexed: indexType must be 'unsigned_int' or 'unsigned_short' Assertion failed: (indexType == jet_component_type_unsigned_int |

问题 I am making an application for tvOS. I have a view that contains a UIButton and a custom UIView that contains a couple other custom views. The simulator is only able to highlight the UIButton and not the custom view.

问题 I started developing apps for Apple TV and I have this problem whit buttons. I have a screen where are several buttons on bottom of the screen and then there is one, which is in the middle (see screenshot to understand). The problem is that I can't get focused the middle button. Focus is only on bottom three buttons.
