如何从AVPlayer获取持续时间（不是AVAudioPlayer）？ [英] How to get Duration from AVPlayer (Not AVAudioPlayer)?

问题描述

我想为我的AVPlayer制作一个UISlider（擦洗器）。但由于这不是AVAudioPlayer，因此它没有内置的持续时间。有关如何创建滑块以进行快进，快退和播放进度的任何建议？

I would like to make a UISlider(scrubber) for my AVPlayer. But since this is not an AVAudioPlayer, it doesn't have a built in duration. Any suggestion on how to create the Slider for fast forward, rewind and progress of the playback?

我在AVPlayer上阅读了doc，它有一个内置的seekToTime或seekToTime：toleranceBefore：toleranceAfter：。我真的不明白。这会是我滑块的答案吗？ AVPlayer还有addPeriodicTimeObserverForInterval：queue：usingBlock：，这是用于获取我的音轨的持续时间吗？有人能举例说明如何实现这段代码吗？我不是Apple的文档粉丝。这似乎很难理解。

I read the doc on AVPlayer, it has a built in seekToTime or seekToTime:toleranceBefore:toleranceAfter:. I don't really understand it. Would this be the answer for my slider? AVPlayer also has addPeriodicTimeObserverForInterval:queue:usingBlock:, is this for getting the duration of my track? Can someone give me an example on how to implement this code? I am not a fan of Apple's documentation. It seems very hard to understand.

推荐答案

self.player.currentItem.asset.duration

知道了！
