[[NSNotificationCenter defaultCenter] addObserver:self 
                selector:@selector(MPMoviePlayerLoadStateDidChange:) 
                 name:MPMoviePlayerLoadStateDidChangeNotification object:mPlayer.moviePlayer]; 


- (void)MPMoviePlayerLoadStateDidChange:(NSNotification *)notification 
     { 
      if ((mPlayer.moviePlayer.loadState & MPMovieLoadStatePlaythroughOK) == MPMovieLoadStatePlaythroughOK) 
      { 
       NSLog(@"content play length is %g seconds", mPlayer.moviePlayer.duration); 
       timeRemain = [NSTimeIntervalSince1970 [mPlayer.moviePlayer.duration]-[mPlayer.moviePlayer.currentPlaybackTime]]; 
       NSLog(@"Time Remaining::%g",timeRemain); 
      } 
     }

我想獲得播放視頻的剩餘時間，但沒有得到，可以any1幫助我嗎？ – Seema 2014-09-24 12:15:05

MPMoviePlayerController持續時間已經在幾秒鐘內。所以

[mPlayer.moviePlayer.duration]-[mPlayer.moviePlayer.currentPlaybackTime]

將返回當前時間和總時間爲NSTimeInterval的秒數。

是的，但我想播放視頻時觀察員通知，所以我不知道它。你能告訴我如何得到它嗎？ – Seema 2014-09-24 12:30:31

-(void)updateDuration 
{ 
    int remainingDuration = mPlayer.moviePlayer.duration - mPlayer.moviePlayer.currentPlaybackTime; 

    if (mPlayer.moviePlayer.currentPlaybackTime != mPlayer.moviePlayer.duration ) { 

     [btnRemainingDuration setTitle:[NSString stringWithFormat:@"Video ends in %d seconds", remainingDuration] forState:UIControlStateNormal]; 
    } 
}
