MPMovie播放器如何获得播放时间？

Question

I was trying to go through the iPhone's sample code for mediaplayer.

I want to be able to capture the amount of time the media player has played the video. The duration at which the media player has stopped. Is there a method or property that will tell me the duration of play of the media??

Answer 1

Yes, You can use the property "duration" defined by MPMediaPlayerController. Plese try it out and check the output. U can refer the here duration property

Answer 2

Unfortunately the current API for MPMoviePlayerController allows basically no control. You can tell it to play and stop... otherwise where's a delegate method so you can be notified when the movie finishes playing and that's it, there's no additional controls. (a real bummer)

However, while we cant discuss the new 3.2 SDK yet, I'll give you a tip and say go look at the documentation of MPMoviePlayer in 3.2 and I think you'll be happy.

Answer 3

moviePlayer.currentPlaybackTime

不可能在上面执行KVO，但是您可以像我一样创建一个ScheduledTimer，它每秒更新一次，以检查当前播放时间是什么，并相应地更新图形:)
