允许“自动锁定"在播放视频时 [英] Allow "auto lock" while video is being played

问题描述

无论我使用的是MPMoviePlayerController 还是AVPlayer (AVFoundation)，iOS 都不允许设备自动锁定(进入睡眠模式)，同时视频播放.

No matter whether I am using MPMoviePlayerController or AVPlayer (AVFoundation), the iOS does not allow the device to auto lock (to enter sleep mode) while the video is playing.

我有一个案例，在后台不断循环播放极慢的视频.播放此视频时，设备永远不会进入睡眠状态.

I have a case where an extremely slow video is constantly being played in a loop in the background. While this video is playing, the device never goes to sleep.

到目前为止，我唯一的选择是检测用户何时没有进行任何操作，然后暂停视频.之后，设备会倒计时 iOS 设置中指定的自动锁定"持续时间.

So far, the only option I have is to detect when a user did not make any actions for a while and then pause the video. After that, the device counts down the "auto lock" duration that is specified in iOS Settings.

我正在寻找 AVPlayer 的替代方案，这将使这成为可能.

I am looking for an alternative to AVPlayer that will make this possible.

是否可以设置AVPlayer让设备在播放视频时进入睡眠状态?

我有一个在 UIWebView 中使用 HTML5 视频的想法，但 iOS 不允许在这些视频上自动播放.

I had an idea to use HTML5 video inside a UIWebView, but iOS does not allow autoplay on those.

推荐答案

记住这是私有 API，我不确定你是否可以将它用于 appstore 发布.

在 iOS 9 上测试.

Tested on iOS 9.

AVPlayer *player = // alloc init...
if ([player respondsToSelector:NSSelectorFromString(@"_preventsSleepDuringVideoPlayback")]) {
    [player setValue:@(NO) forKey:@"preventsSleepDuringVideoPlayback"];
}
