如何通过点击UITableViewCell IOS7来播放视频

Question

您好，在我的应用程序中，我已将视频网址从我的服务器传递为json，并且我在UITableView中显示了视频标题。我想通过点击单元格来播放视频。我尝试了一些方法但它们没有用。

我的JSON获取视频代码：

-(void)details{
    NSString *urlString = [NSString stringWithFormat:@"myurl"];



   NSURL *url = [NSURL URLWithString:urlString];

   NSString *jsonString = [NSString stringWithContentsOfURL:url encoding:NSUTF8StringEncoding error:nil];

   NSLog(@"the str==%@",jsonString);

   NSDictionary *results = [NSJSONSerialization JSONObjectWithData:[jsonString dataUsingEncoding:NSUTF8StringEncoding] options:0 error:nil];

   videoarray = [[NSMutableArray alloc]init];
   NSArray *array=[results objectForKey:@"videos"];



  for (int i=0; i<[array count]; i++) {


    NSString *filed =[[array objectAtIndex:i]objectForKey:@"v_name"];

   //my video url stored in a nstring video
    NSString *video =[[array objectAtIndex:i]objectForKey:@"video"];

    NSLog(@"the url==%@",video);
    NSLog(@"the field==%@",filed);

    // i have ready nsobject to store the data and im adding to the nsmutablearray

    video1 *myimg =[[video1 alloc]initWithname:filed andvideo:video];

    [videoarray addObject:myimg];

    }

    [self.mytableview reloadData];  
  }

当我打印网址时，它的json就像这样。

the url==http://jesusredeems.tv/media/videos/2014 Promise Message/Promise Message 2014-Part 2.mp4

之后在didSelectRowAtIndexPath方法中我就这样给出了。

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

   video1 * curnt = [videoarray objectAtIndex:indexPath.row];


  MPMoviePlayerController *player = [[MPMoviePlayerController alloc]initWithContentURL: [NSURL URLWithString:curnt.video]];
  [[player view] setFrame: [self.view bounds]];  // frame must match parent view
  [self.view addSubview: [player view]];
  [player play];
 }

我已经使用上面的代码在点击单元格的同时播放视频，但在点击它后显示黑屏这样。

我已经在Media player中导入了UITableView，但它无效。请告诉我如何解决此问题以及上述代码中我出错的地方

感谢。

试试这个

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




     //your array here

    NSString * currentVideo = [array1 objectAtIndex:indexPath.row];


   _moviePlayerTemp = [[MPMoviePlayerController alloc]initWithContentURL: [NSURL URLWithString:[self urlencode:currentVideo]]];
    [[_moviePlayerTemp view] setFrame: CGRectMake(0, 0, self.view.bounds.size.width, self.view.bounds.size.height)];
// frame must match parent view
    [self.view addSubview: [_moviePlayerTemp view]];
    [_moviePlayerTemp setShouldAutoplay:YES];
    [_moviePlayerTemp prepareToPlay];
    [_moviePlayerTemp play];

}

-(NSString *)urlencode:(NSString *)str
{
    NSString *encodeString=(NSString *)CFBridgingRelease(CFURLCreateStringByAddingPercentEscapes(NULL, (CFStringRef)str, NULL, (CFStringRef)@"", kCFStringEncodingUTF8));
    return encodeString;
}

并像这样打电话。

NSString *string=@"http://jesusredeems.tv/media/videos/2014 Promise Message/Promise Message 2014-Part 2.mp4";
        NSString *temp=[self urlencode:string];

尝试按照以下帖子创建MPMoviePlayerController：play a .mp4 or .mov video from either an Internet URL or a local file in iOS?

除此之外，创建MPMoviePlayerController变量是函数中的iVar变量NOT局部变量，就像在didSelectRowAtIndexPath

中一样

应用内的视频。

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


   NSString *path  =[[NSBundle mainBundle]pathForResource:@"YOUR Video File Name" ofType:@"mp4"];
  _moviePlayer=[[MPMoviePlayerController alloc]initWithContentURL:[NSURL fileURLWithPath:path]];
[[NSNotificationCenter defaultCenter]
 addObserver:self
 selector:@selector(playbackFinished:)
 name:MPMoviePlayerPlaybackDidFinishNotification
 object:_moviePlayer];
[_moviePlayer setScalingMode:MPMovieScalingModeAspectFit];
[_moviePlayer setFullscreen:FALSE];
self.moviePlayer.controlStyle = MPMovieControlStyleDefault;
 _moviePlayer.view.frame = self.videoPlayerView.bounds;
  [_moviePlayer setFullscreen:NO];
 _videoPlayerView.hidden=NO;
  [self.videoPlayerView addSubview:_moviePlayer.view];
  [self.view bringSubviewToFront:self.videoPlayerView];

   [_moviePlayer prepareToPlay];
   [_moviePlayer play];

}
//After finishing playing.


-(void)finishedPlaying:(NSNotification *)sender
{
 MPMoviePlayerController *player  =[sender object];
 [player stop];
//    [player.view removeFromSuperview];
   self.videoPlayerView.hidden=YES;
   if([player isFullscreen])
    [self dismissViewControllerAnimated:YES completion:nil];
   _moviePlayer = nil;
  }
