如何在iPhone应用程序中将MPMoviePlayerController转发到指定时间?
我是iPhone开发的新手，我需要播放某些链接上的视频，并且通过点按要转发电影控制器的标签，在MPMoviePlayerViewController上叠加了三个标签(例如跳转到1:20")到那个标记的时间.我已经尝试了两个函数，分别是"setCurrentTime"和"initialPlaybackTime"，但是这些函数都没有给我带来结果.
I am new to iPhone development, I need to play videos which are on some link and I have overlay of three labels(like 'jump to 1:20') on the MPMoviePlayerViewController by tapping on the label the movie controller is forwarded to that labeled time. I have tried two functions namely "setCurrentTime" and "initialPlaybackTime" but none of these didn't give result for me..
