    <p>I have an app that uses a UIScrollView to display content created by Interface Builder. I add a UITextView to it programmatically because its content is changeable and I want it to resize. This is done! The problem comes when resizing the UIScrollView to fit the new UITextView size. I just can't get it done.. I tried various methods including: </p> <p><code>CGRect contentRect = CGRectZero; for (UIView *view in self.scrollView.subviews) contentRect = CGRectUnion(contentRect, view.frame); self.scrollView.contentSize = contentRect.size;</code></p> <p>I think the problem is because it is built by Interface Builder but the UIScrollView contains other elements as well so I can't create it programmatically. I was hoping someone could help me on this.</p> <p><strong>UPDATE 1</strong>: I have both the UIView and the UIScrollView's heights set to 1024 from the Interface Builder.</p> <p><strong>UPDATE 2 (FIX)</strong>: I was able to fix this problem by issuing a timer at the end of the <code>viewDidLoad</code> method like so:</p> <p><code>[NSTimer scheduledTimerWithTimeInterval:0.00001 target:self selector:@selector(resizeScrollView) userInfo:nil repeats:NO]</code></p> <p>and then resizing it in the <code>resizeScrollView</code> method here:</p> <p><code>-(void)resizeScrollView { CGFloat scrollViewHeight = 0.0f; for (UIView* view in scrollView.subviews) { scrollViewHeight += view.frame.size.height; } [scrollView setContentSize:(CGSizeMake(320, scrollViewHeight-50))]; }</code></p> <p>Thanks for all the help! </p> <p><strong>NOTE</strong>: This solution was inspired by Maniac One's answer. Thanks!</p>

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.
