mpmovieplayercontroller

问题 I realise that a similar question has been posted before, but I really can't seem to find a solution that works for me. I have a MoviePlayer class which stores an ivar of MPMoviePlayerController, and I have the following method in the class: -(void)playMovie:(NSString *)movieName { NSURL *movieURL; NSBundle *bundle = [NSBundle mainBundle]; if(bundle) { NSString *moviePath = [bundle pathForResource:movieName ofType:@"m4v"]; if(moviePath) { movieURL = [NSURL fileURLWithPath:moviePath]; } }

问题 The question is - how to get the movie length from MPMoviePlayerController object? I need this to create a progress bar. I have the method [myPlayer currentTime] to move progress bar while movie is playing. And the [myPlayer setCurrentTime: doubleVal] to rewind the movie. But I can't use all this without information about movie length, or movie end time. Also, maybe exists another player to use in iPhone, instead of MPMoviePlayerController ? 来源： https://stackoverflow.com/questions/1188543
