    <p>I'm loading content into a UIWebView with the following call:</p> <pre><code>NSString *detailHtmlString = [NSString stringWithFormat:@"&lt;html&gt;&lt;head&gt;&lt;style&gt;body {background: black;color: white;line-height: 1.4em; font-family: sans-serif; margin: 0; padding: 0 0 30px 0;width: 280px;} p {margin-top: 10px;}&lt;/style&gt;&lt;/head&gt;&lt;body id=\"content\"&gt;%@&lt;/body&gt;&lt;/html&gt;",[currentWeek objectForKey:@"post_content"]]; [weekDetailController.movie_detail loadHTMLString:detailHtmlString baseURL:nil]; </code></pre> <p>Then, after it it finishes loading:</p> <pre><code>- (void) webViewDidFinishLoad:(UIWebView *)sender { [self performSelector:@selector(calculateWebViewSize) withObject:nil afterDelay:0.1]; } - (void) calculateWebViewSize { [weekDetailController.movie_detail sizeToFit]; float newHeight = [[weekDetailController.movie_detail stringByEvaluatingJavaScriptFromString :@"document.getElementById(\"content\").offsetHeight"] floatValue]; newHeight += 300; //height of the other elements NSLog(@"Height: %f",newHeight); CGRect frame = weekDetailController.movie_detail.frame; NSLog(@"Height was: %f",frame.size.height); frame.size.height = newHeight; weekDetailController.movie_detail.frame = frame; [scrollView.scrollView setContentOffset:CGPointZero]; [scrollView.scrollView setContentSize:CGSizeMake(frame.size.width, frame.size.height)]; } </code></pre> <p>This works great the first time the view is loaded, but on subsequent views, when different content has been loaded into the UIWebView (using the same call as above), the JavaScript call to get the height returns larger and larger values -- even if the content is smaller, it still returns the height of the largest amount of content that had been in the view at some point. I've tried loading a blank HTML string into the view to "clear" it, but that doesn't seem to help either.</p> <p>Any hints would be appreciated!</p>

    1. COUhmm... You are not resetting newHeight in the code above, merely adding 300 on each call...

    2. COwhoops - went overboard when removing commented code and removed a line (uncommented) that set newHeight -- original post has been modified

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
