    <p>I have to update a small amount of text in a scrolling UITextView. I'll only be inserting a character where the cursor currently is, and I'll be doing this on a press of a button on my navigation bar.</p> <p>My problem is that whenever I call the setText method of the text view, it jumps to the bottom of the text. I've tried using contentOffset and resetting the selectedRange but it doesn't work! Here's my example:</p> <pre><code>// Remember offset and selection CGPoint contentOffset = [entryTextView contentOffset]; NSRange selectedRange = [entryTextView selectedRange]; // Update text entryTextView.text = entryTextView.text; // Try and reset offset and selection [entryTextView setContentOffset:contentOffset animated:NO]; [entryTextView setSelectedRange: selectedRange]; </code></pre> <p>Is there any way you can update the text without any scroll movement at all... as if they'd just typed something on the keyboard?</p> <p>Edit:</p> <p>I've tried using the textViewDidChange: delegate method but it's still not scrolling up to the original location. </p> <pre><code>- (void)textViewDidChange:(UITextView *)textView { if (self.programChanged) { [textView setSelectedRange:self.selectedRange]; [textView setContentOffset:self.contentOffset animated:NO]; self.programChanged = NO; } } - (void)changeButtonPressed:(id)sender { // Remember position self.programChanged = YES; self.contentOffset = [entryTextView contentOffset]; self.selectedRange = [entryTextView selectedRange]; // Update text entryTextView.text = entryTextView.text; } </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.
