UIWebView *webview=[[UIWebView alloc] initWithFrame:CGRectMake(10, 10, 150, 120)];
NSString *media=@"http://www.youtube.com/watch?v=kG2BYhjQIKQ";
NSString *html = [NSString stringWithFormat:youTubeVideoHTML,media, 150, 120];
[webview loadHTMLString:html baseURL:nil];
[cell.contentView addSubview:webview];
它不工作，它只显示白色视图。
要在 webView 上播放 youtube 视频，请尝试以下操作：
NSString *youTubeVideoHTML = @"<html><head>\
<body style=\"margin:0\">\
<embed id=\"yt\" src=\"%@\" type=\"application/x-shockwave-flash\" \
width=\"%0.0f\" height=\"%0.0f\"></embed>\
</body></html>";
// Populate HTML with the URL and requested frame size
NSString *html = [NSString stringWithFormat:youTubeVideoHTML, urlString, frame.size.width, frame.size.height];
// Load the html into the webview
[self loadHTMLString:html baseURL:nil];
[webview loadHTMLString:html baseURL:nil]; 用于加载到 UITextview 如果你想使用 UIwebview 手段
[webView loadRequest:[NSURLRequest requestWithURL:url]];
