ios - 使用 MPMoviePlayerController 播放 youtube 视频

Question

我长期以来一直使用 html 字符串通过 UIWebView 播放 youtube 视频，问题是我想获得播放状态更改的通知。我决定创建一个 MPMoviePlayerController 并通过它播放 youtube 视频，但似乎无法正常工作。我在 viewdidload 中使用以下代码:

NSString *urlAddress = @"http://www.youtube.com/watch?v=m01MYOpbdIk";
NSURL *url = [NSURL URLWithString:urlAddress];
CGFloat width = [UIScreen mainScreen].bounds.size.width;
CGFloat height = [UIScreen mainScreen].bounds.size.height;
movie = [[MPMoviePlayerController alloc] initWithContentURL:url];
movie.scalingMode=MPMovieScalingModeAspectFill;
movie.view.frame = CGRectMake(0.0, 0.0, width, height);
[self.view addSubview:movie.view];
[movie play];

给我这个错误:

_itemFailedToPlayToEnd: {
    kind = 1;
    new = 2;
    old = 0;
 }

对我来说，这个库运行得非常完美! https://github.com/hellozimi/HCYoutubeParser

moviePlayer = [[MPMoviePlayerController alloc] init];    
moviePlayer.shouldAutoplay = YES;
moviePlayer.fullscreen = YES;
moviePlayer.repeatMode = MPMovieRepeatModeNone;
moviePlayer.controlStyle = MPMovieControlStyleDefault;
moviePlayer.movieSourceType = MPMovieSourceTypeFile;
moviePlayer.scalingMode = MPMovieScalingModeAspectFit;

在这个调用方法之后。

[self callYouTubeURL:[NSString stringWithFormat:@"http://www.youtube.com/embed/%@",_urlcode]];

在此方法中解析 youtube 链接。

- (void)callYouTubeURL:(NSString *)urlLink
{

    NSURL *url = [NSURL URLWithString:urlLink];
    actvity.hidden = NO;
    [HCYoutubeParser thumbnailForYoutubeURL:url thumbnailSize:YouTubeThumbnailDefaultHighQuality completeBlock:^(UIImage *image, NSError *error) {

        if (!error) {

            [HCYoutubeParser h264videosWithYoutubeURL:url completeBlock:^(NSDictionary *videoDictionary, NSError *error) {


                NSDictionary *qualities = videoDictionary;

                NSString *URLString = nil;
                if ([qualities objectForKey:@"small"] != nil) {
                    URLString = [qualities objectForKey:@"small"];
                }
                else if ([qualities objectForKey:@"live"] != nil) {
                    URLString = [qualities objectForKey:@"live"];
                }
                else {
                    [[[UIAlertView alloc] initWithTitle:@"Error" message:@"Couldn't find youtube video" delegate:nil cancelButtonTitle:@"Close" otherButtonTitles: nil] show];
                    return;
                }
                _urlToLoad = [NSURL URLWithString:URLString];


                [self urlLoadintoPlayer];

            }];
        }
        else {
            UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Error" message:[error localizedDescription] delegate:nil cancelButtonTitle:@"Dismiss" otherButtonTitles:nil];
            [alert show];
        }
    }];
}

在此加载后，将新解析的 url 加载到播放器中。

-(void)urlLoadintoPlayer
{
    moviePlayer.contentURL = _urlToLoad;
}
