Answer extension for documentation purposes to maybe help someone else: I had the same desire (clear content before loading next url) but had a UIWebView delegate set to receive <code>webviewDidFinishLoad:(UIWebView)webview</code> message and update another part of UI in response. Problem: the call to clear the content to also called delegate method, so getting false-hits (that is, getting call when clear is done, too, but delegate is coded to expect call only when real content is loaded). Solution: use a known URL for clear, and have <code>webviewDidFinishLoad:</code> ignore calls made when that URL is finished: <pre><code>- (void) startLoadOfNextURL:(NSURL*)url { // clear: [self.webView loadHTMLString:@"" baseURL:nil]; // Load real next URL NSURLRequest* request = [NSURLRequest requestWithURL:url]; [self.webView loadRequest:request]; } - (void)webViewDidFinishLoad:(UIWebView *)webView { NSLog(@"WebView finished loading: %@", webView); if ([self.webView.request.URL.absoluteString isEqualToString:@"about:blank"]) { NSLog(@" This is Blank. Ignoring as false event."); } else { NSLog(@" This is a real url"); [self updateUIInSomeWay]; } } </code></pre> Note: using this: <pre><code> [self.webView loadHTMLString:@"about:blank" baseURL:nil]; </code></pre> actually causes the words "about:blank" to appear as text in the webview's content pane! Final complication: In practice, with my two <code>[webview load...]</code> calls so close together, I was finding that instead of a "loaded" event for the clear, the webview was actually canceling it in favor of the second request and calling <code>webView: didFailLoadWithError:</code> for the first load request. Thus, I had to put similar code in that event: <pre><code>- (void)webView:(UIWebView *)webView didFailLoadWithError:(NSError *)error { NSLog(@"WebView error on: %@", webView); NSLog(@"Error is: %@", error); NSURL* failingURL = [error.userInfo objectForKey:@"NSErrorFailingURLKey"]; if ([failingURL.absoluteString isEqualToString:@"about:blank"]) { NSLog(@" This is Blank. Ignoring."); } else { NSLog(@" This is a real URL."); [self doSomethingAboutError]; } } </code></pre>

A row detail

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.
