    <p>In my app, I have a button which, when pressed, lets you watch a youtube video (a movie trailer). Within the app, without launching safari. Below you can see a code snippet. This code works pefrectly fine under iOS5. However, in iOS 6, the UIButton in findButtonInView is always nil. Any ideas what might be the reason?</p> <pre><code>youtubeWebView.delegate = self; youtubeWebView.backgroundColor = [UIColor clearColor]; NSString* embedHTML = @" &lt;html&gt;&lt;head&gt; &lt;style type=\"text/css\"&gt; body {background-color: transparent; color: white; }&lt;/style&gt;&lt;/head&gt;&lt;body style=\"margin:0\"&gt;&lt;embed id=\"yt\" src=\"%@?version=3&amp;app=youtube_gdata\" type=\"application/x-shockwave-flash\"width=\"%0.0f\" height=\"%0.0f\"&gt;&lt;/embed&gt;&lt;/body&gt;&lt;/html&gt;"; NSURL *movieTrailer; if(tmdbMovie) movieTrailer = tmdbMovie.trailer; else movieTrailer = [NSURL URLWithString:movie.trailerURLString]; NSString *html = [NSString stringWithFormat:embedHTML, movieTrailer, youtubeWebView.frame.size.width, youtubeWebView.frame.size.height]; [youtubeWebView loadHTMLString:html baseURL:nil]; [self addSubview:youtubeWebView]; - (void)webViewDidFinishLoad:(UIWebView *)_webView { isWatchTrailerBusy = NO; [manager displayNetworkActivityIndicator:NO]; //stop the activity indicator and enable the button UIButton *b = [self findButtonInView:_webView]; //TODO this returns null in case of iOS 6, redirect to the youtube app if(b == nil) { NSURL *movieTrailer; if(tmdbMovie) { movieTrailer = tmdbMovie.trailer; } else { movieTrailer = [NSURL URLWithString:movie.trailerURLString]; } [[UIApplication sharedApplication] openURL:movieTrailer]; } else { [b sendActionsForControlEvents:UIControlEventTouchUpInside]; } } - (UIButton *)findButtonInView:(UIView *)view { UIButton *button = nil; if ([view isMemberOfClass:[UIButton class]]) { return (UIButton *)view; } if (view.subviews &amp;&amp; [view.subviews count] &gt; 0) { for (UIView *subview in view.subviews) { button = [self findButtonInView:subview]; if (button) return button; } } return button; } </code></pre>

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
