    copied!<p>Sorry for the long question, but I have been stuck on this for days and have exhausted all other help.</p> <p>Currently, I have a tab bar application with four tabs. In the second tab (SecondViewController), I have a segmented controller at the top that should switch between "videos" and "images". The videos page should have around 5 youtube videos loaded in UIWebView using the code <a href="http://iphonedevelopertips.com/video/display-youtube-videos-without-exiting-your-application.html" rel="nofollow">here</a>. The images view should contain around 5 thumbnails that, when clicked on, open into a larger picture. My problem is that I have tried out many different ways of accomplishing this, and none seem to work to any extent. Really the main thing I am looking for here is the recommended way of going about switching between two views using a segmented controller and if it is possible to load the views from different files (videosView.h/m and imagesView.h/m). </p> <p>In SecondViewController.m, I have the app respond to the UISegmentedController using the following, though I have absolutely no idea if this is even close to correct.</p> <pre><code>- (IBAction)segmentedControlChanged { switch (segmentedControl.selectedSegmentIndex) {case 0: [self.view addSubview:videosView.view]; [imagesView.view removeFromSuperview]; NSLog(@"1"); break; case 1: [self.view addSubview:imagesView.view]; [videosView.view removeFromSuperview]; NSLog(@"2"); break; default: break; } } </code></pre> <p>In videosView.h, I only have the following:</p> <pre><code>#import &lt;UIKit/UIKit.h&gt; @interface videosView : UIWebView { } - (videosView *)initWithStringAsURL:(NSString *)urlString frame:(CGRect)frame; @end </code></pre> <p>In videosView.m, I have the following, though I am getting a warning on the initWithFrame line. </p> <pre><code>- (videosView *)initWithStringAsURL:(NSString *)urlString frame:(CGRect)frame; { if (self = [super init]) { // Create webview with requested frame size self = [[UIWebView alloc] initWithFrame:frame]; // HTML to embed YouTube video NSString *youTubeVideoHTML = @"&lt;html&gt;&lt;head&gt;\ &lt;body style=\"margin:0\"&gt;\ &lt;embed id=\"yt\" src=\"%@\" type=\"application/x-shockwave-flash\" \ width=\"%0.0f\" height=\"%0.0f\"&gt;&lt;/embed&gt;\ &lt;/body&gt;&lt;/html&gt;"; // 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]; } return self; } @end </code></pre> <p>imagesView is made, but has no added code it in currently, as I am just trying to get the videos sorted out first. </p>
