当UIWebview我尝试播放任何视频时youtube它崩溃了我的xcode，我使用的是iOS6 ..我只是使用了UIWebview加载url youtube到它...我需要嵌入媒体播放器来播放视频吗？

我还需要做什么才能在 youtube 上播放视频UIWebView

代码

- (void)viewDidLoad
{
[super viewDidLoad];


 NSString *newVersionHTML = @"<html>\
<style>body{padding:0;margin:0;}</style>\
<iframe width=\"%0.0f\" height=\"%0.0f\" src=\"http://www.youtube.com/embed/%@?modestbranding=1;title=;showinfo=0;rel=0;controls=0\" frameborder=\"0\" allowfullscreen></iframe>\
</html>";

  NSString *htmlToLoad = [NSString stringWithFormat:newVersionHTML, webView.frame.size.width, webView.frame.size.height,videoId];
 [webView loadHTMLString:htmlToLoad baseURL:nil];
 webView.delegate = self;
// self.webView.mediaPlaybackRequiresUserAction = NO;


webView=[[UIWebView alloc]initWithFrame:CGRectMake(0, 0, 1024, 768)];


[self.webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:[NSString stringWithFormat:@"http://www.youtube.com/"]]]];
 [self.view addSubview:webView];

}

只需在以下代码中传递 youtube 视频的 videoId 即可播放 youtube 视频

例如，如果链接是http://www.youtube.com/watch?v=DTbgpJAggg0&feature=youtube_gdata那么

- (void)viewDidLoad
{
   [super viewDidLoad];

   webView=[[UIWebView alloc]initWithFrame:CGRectMake(0, 0, 1024, 768)];

   [self.view addSubview:self.webView];

   self.webView.delegate = self;


   NSString *newVersionHTML = @"<html>\
<style>body{padding:0;margin:0;}</style>\
<iframe width=\"%0.0f\" height=\"%0.0f\" src=\"http://www.youtube.com/embed/%@?modestbranding=1;title=;showinfo=0;rel=0;controls=0\" frameborder=\"0\" allowfullscreen></iframe>\
</html>";

    NSString *htmlToLoad = [NSString stringWithFormat:newVersionHTML, self.webView.frame.size.width, self.webView.frame.size.height,videoId];
    [self.webView loadHTMLString:htmlToLoad baseURL:nil];

}

只需在 webview 中使用 OPEN youtube 主页：

在 .h 中：

@property (nonatomic, retain) UIWebView *webView;

在 .m 中：

- (void)viewDidLoad
{
    [super viewDidLoad];

    _webView=[[UIWebView alloc]initWithFrame:CGRectMake(0, 0, 1024, 768)];

    [self.view addSubview:self.webView];

    self.webView.delegate = self;


    [self.webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:[NSString stringWithFormat:@"http://www.youtube.com/"]]]];

}
