I am using MPMoviePlayerController to play video. I want to play part of video on clicking play button. For example if my video is of 200 seconds, i want to play video from 50th-100th second. Even i'm not able to get time-length video played at particular instance like at the time of pausing.

推荐答案

MPMoviePlayerController具有两个属性:initialPlaybackTime和endPlaybackTime，您可以将其设置为NSTimeInterval(=用来在其中指定时间间隔的double秒)来控制影片播放的开始和结束时间.
例如，此代码将从10秒到20秒播放电影:

MPMoviePlayerController has two properties: initialPlaybackTime and endPlaybackTime that you can set to an NSTimeInterval (= double used to specify a time interval in seconds) to control the start and end time for the playback of the movie.
This code for example will play the movie from the 10th second to the 20th second:

[moviePlayerController setInitialPlaybackTime:10.f];
[moviePlayerController setEndPlaybackTime:20.f];
