UIWebview不会在iFrame中加载YouTubevideo

我试图加载一个HTMLstring到UIWebView 。 HTML包含一个iframe ,但不会在webview中加载。

这是我的代码,

 webDescription = [[UIWebView alloc]initWithFrame:CGRectMake(0, 255,self.view.bounds.size.width, 20)]; [[webDescription scrollView] setBounces: NO]; webDescription.delegate = self; NSString *myDescriptionHTML = [NSString stringWithFormat:@"<html> \n" "<head> \n" "<style type=\"text/css\"> \n" "body {font-family: \"%@\"; font-size: %@; COLOR:#111111; background-color:transparent; padding:10px 5px 15px 20px;}\n" "</style> \n" "</head> \n" "<body>%@</body> \n" "</html>", @"MyriadPro-Regular", [NSNumber numberWithInt:12], _group.gro_content]; [webDescription setBackgroundColor:[UIColor clearColor]]; [webDescription setOpaque:NO]; [webDescription loadHTMLString:myDescriptionHTML baseURL:nil]; [scrollView addSubview:webDescription]; 

我该如何解决这个问题?

试试这个代码,

 - (void)embedYouTube:(NSString *)youtubeUrl frame:(CGRect)frame { NSString *embedHTML = @"\ <html><head>\ <style type=\"text/css\">\ body {\ background-color: transparent;\ color: white;\ }\ </style>\ </head><body style=\"margin:0\">\ <embed id=\"yt\" src=\"%@\" type=\"application/x-shockwave-flash\" \ width=\"%0.0f\" height=\"%0.0f\"></embed>\ </body></html>"; NSString *html = [NSString stringWithFormat:embedHTML, youtubeUrl, frame.size.width, frame.size.height]; UIWebView *videoView = [[UIWebView alloc] initWithFrame:frame]; [videoView loadHTMLString:html baseURL:nil]; [playerview addSubview:videoView]; }
