MPMoviePlayerViewController不能設置當前播放時間

我想設置的MPMoviePlayerController在MPMoviePlayerViewController的currentPlaybackTime財產，使其恢復播放從實時視頻（HLS流），當應用程序主動辭職它已停止。這裏是我的代碼：MPMoviePlayerViewController不能設置當前播放時間

//the functinon that sets playback time 
    - (void)setCurrentPlayTime:(NSNumber *)time { 
     if (self.moviePlayer.currentPlaybackTime < [time floatValue] - 10.0) { 
      [self.moviePlayer setCurrentPlaybackTime:(NSTimeInterval)[time floatValue]]; 
     } 
    } 

    //app did become active callback 
    - (void) applicationDidBecomeActiveNotification:(NSNotification*)notification { 
     if (!isnan(_curPlayTime) && _curPlayTime > 0.0) { 
      [self performSelector:@selector(setCurrentPlayTime:) withObject:[NSNumber numberWithFloat:_curPlayTime] afterDelay:0.1]; 
     } 
    } 

    //player load state did change callback 
    -(void)playerLoadStateDidChange:(NSNotification *)notification { 
    MPMoviePlayerController *player = notification.object; 
    MPMovieLoadState loadState = player.loadState; 
if (loadState & MPMovieLoadStatePlaythroughOK) { 
     if (!isnan(_curPlayTime) && _curPlayTime > 0.0) { 
      [self performSelector:@selector(setCurrentPlayTime:) withObject:[NSNumber numberWithFloat:_curPlayTime] afterDelay:0.1]; 
      _curPlayTime = 0.0; 
     } 
}

當我只需輕按Home鍵，然後重新打開應用程序，並且如果我得到的來電，但拒絕它，它的工作原理。但是，如果我接聽電話，我完成了電話後，打從0.0忽略setCurrentPlaybackTime方法調用開始。有誰知道，問題在哪裏，並且可能是任何示例，應該怎樣做才能正確工作？

不確定是否這是問題，但您正在搜索的選擇器是setCurrentPlayTime而不是setCurrentPlay * 返回 *時間。

沒有發現currentPlayTime屬性或setCurrentPlayTime既不的MPMoviePlayerController接口也不在MPMediaPlayback協議。你能不能給一個鏈接文檔呢？ – 2013-07-31 09:00:57

property currentPlaybackTime http://developer.apple.com/library/ios/#documentation/mediaplayer/reference/MPMediaPlayback_protocol/Reference/Reference.html 它的setter因此setCurrentPlaybackTime – Nuthinking 2013-08-01 10:11:53

所以它仍然是currentPlay * back * Time，而不是currentPlayTime 。 – 2013-08-07 12:31:57
