UITableView在關閉後不記得它的滾動位置moviePlayerController

-1

我有一個UITableView自定義單元格，在這個表格中，一個視頻列表顯示10乘10從服務器使用分頁概念。當你點擊視頻列表，然後視頻開始在moviePlayerController中播放，但是當你點擊完成moviePlayerController的Button時，你的視頻列表被刷新。我想停止這個刷新，並希望看到UITableView與以前播放視頻相同。UITableView在關閉後不記得它的滾動位置moviePlayerController

請參閱代碼：

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{ 

    [tableView deselectRowAtIndexPath:indexPath animated:YES]; 
    CurrentVideoIndex =indexPath; 
    NSDictionary *VideoUrlDic = [videoList objectAtIndex:indexPath.row]; 
    NSString *VideoUrl = [VideoUrlDic objectForKey:@"playUrl"]; 
    //NSLog(@"VideoUrl is ::%@",VideoUrl); 

    NSURL *fileURL = [NSURL URLWithString:VideoUrl]; 

    moviePlayerController= [[MPMoviePlayerViewController alloc] initWithContentURL:fileURL]; 

    [[moviePlayerController moviePlayer] prepareToPlay]; 
    //[[moviePlayerController moviePlayer] setUseApplicationAudioSession:NO]; 
    [[moviePlayerController moviePlayer] setShouldAutoplay:YES]; 
    //[[moviePlayerController moviePlayer] setControlStyle:2]; 
    //[[moviePlayerController moviePlayer] setRepeatMode:MPMovieRepeatModeOne]; 
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(videoPlayBackDidFinish:) name:MPMoviePlayerPlaybackDidFinishNotification object:nil]; 
    [self presentMoviePlayerViewControllerAnimated:moviePlayerController]; 
} 
-(void)videoPlayBackDidFinish:(NSNotification*)notification { 

    [[NSNotificationCenter defaultCenter] removeObserver:self name:MPMoviePlayerPlaybackDidFinishNotification object:nil]; 

    [moviePlayerController.moviePlayer stop]; 
    moviePlayerController = nil; 
    [[NSNotificationCenter defaultCenter] removeObserver:moviePlayerController name:MPMoviePlayerPlaybackDidFinishNotification object:moviePlayerController.moviePlayer]; 

    if (![[self modalViewController] isBeingDismissed]) 
    { 
     [self dismissMoviePlayerViewControllerAnimated]; 
     [moviePlayerController.view removeFromSuperview]; 
     [self hideProgress]; 
    } 

//  [self.tableView scrollToRowAtIndexPath:CurrentVideoIndex atScrollPosition:UITableViewScrollPositionTop animated:NO]; 
    //loading=NO; 
} 

#pragma UIScroll View Method:: 

    - (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView 
    { 
     if (!loading) { 
      float endScrolling = scrollView.contentOffset.y + scrollView.frame.size.height; 
      if (endScrolling >= scrollView.contentSize.height) 
      { 
       [self performSelector:@selector(loadDataDelayed) withObject:nil afterDelay:2]; 

      } 
     } 
    } 

    #pragma UserDefined Method::: 
    -(void)loadDataDelayed{ 

     counter +=10; 
     NSString *count = [NSString stringWithFormat:@"%d",counter]; 
     NSLog(@"count value after Scrolling is :::%@",count); 
     [self createConnection:count]; 
    }

你有一個'viewWillAppear中：'方法？ – Wain

在viewWillAppear我沒有做任何事 – user2621383

你剛剛創建了一個新帳戶來轉貼這個問題：http://stackoverflow.com/questions/17872990/how-to-stop-reload-tableview-after-dissmiss-mpmovieplayerviewcontroller？你應該剛剛更新了原來的問題。 – Wain

當視頻播放器打開presentmodalviewcontroller被打開，當你按下完成按鈕，它駁回modalviewcontroller由於它不管你已經初始化將被釋放，並再次整個視圖被調用，所以要避免使用viewwillappear方法編寫代碼。

當您再次按下完成按鈕時，將會創建tableview，這是解除任何控制器的唯一解決方案。在viewwillappear方法中使用

NSLog（@「」）;

聲明你會來知道我想說

你的意思是說，我必須初始化並在viewwillappear method中分配我的表數組。我試試這個，但問題退出像以前一樣。 – user2621383
