    <p>As it is set up now, I have two UITextViews inside of a UIScrollView. The point of this is that the UITextViews themselves don't scroll, they just get larger (their contentsize) as more text is added. The UIScrollView handles all of the scrolling up and down of the view regardless of how much text there is (think similar to Mail.app where the subject view is above the message view, etc). That said, I've ran into a problem now. When I programmatically add text to my UITextView (in this code, bodyText), the UIScrollView automatically scrolls to the bottom for some reason.</p> <p>To add the text I just do: </p> <pre><code>NSRange selectedRange = [bodyText selectedRange]; NSString *selectedText = [bodyText.text substringWithRange:selectedRange]; bodyText.text = [bodyText.text stringByReplacingCharactersInRange:selectedRange withString:[NSString stringWithFormat:@"&lt;b&gt;%@&lt;/b&gt;", selectedText]]; </code></pre> <p>So, for instance, if I had 2000 pixels vertically of text and was currently scrolled to position 400 and then added text somewhere around there, the UIScrollView would then go all the way down to 2000.</p> <p>I've tried to stop it via subclassing UISCrollView and overriding -setContentOffset, but that freezes all scrolling then.</p> <p>My question is, why does it scroll all the way to the bottom in the first place? The text is added when the user clicks a button somewhere else on the screen, and the scrolling has nothing to do with any finger drags or anything.</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.
