Please write how you upload a video from YouTube. Because the only thing I read is that the Youtube app is no longer in iOS6, but it should continue to work. Anyway, try
NSString* embeddedCode = @"embed code of the youtube video"
UIWebView* videoView = [[UIWebView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)];
[videoView loadHTMLString:embeddedCode baseURL:nil];
[self.window addSubview:videoView];
Hope this works, but in case it's not just a comment, and I can try something else.
