    <p>Here is some code that I have used. Basically, what we're going to do is animate the position of the view whenever a <code>UITextField</code> gets focus. To do this, we must make our <code>UIViewController</code> a delegate of our <code>UITextField</code>s</p> <p>The first delegate method you need to implement is <code>- (void)textFieldDidBeginEditing:(UITextField *)textField</code></p> <pre><code>static const CGFloat KEYBOARD_ANIMATION_DURATION = 0.3; static const CGFloat MINIMUM_SCROLL_FRACTION = 0.2; static const CGFloat MAXIMUM_SCROLL_FRACTION = 0.8; static const CGFloat PORTRAIT_KEYBOARD_HEIGHT = 216; static const CGFloat LANDSCAPE_KEYBOARD_HEIGHT = 162; - (void)textFieldDidBeginEditing:(UITextField *)textField { CGRect textFieldRect = [self.view.window convertRect:textField.bounds fromView:textField]; CGRect viewRect = [self.view.window convertRect:self.view.bounds fromView:self.view]; CGFloat midline = textFieldRect.origin.y + 0.5 * textFieldRect.size.height; CGFloat numerator = midline - viewRect.origin.y - MINIMUM_SCROLL_FRACTION * viewRect.size.height; CGFloat denominator = (MAXIMUM_SCROLL_FRACTION - MINIMUM_SCROLL_FRACTION) * viewRect.size.height; CGFloat heightFraction = numerator / denominator; if (heightFraction &lt; 0.0) { heightFraction = 0.0; } else if (heightFraction &gt; 1.0) { heightFraction = 1.0; } UIInterfaceOrientation orientation = [[UIApplication sharedApplication] statusBarOrientation]; if (orientation == UIInterfaceOrientationPortrait || orientation == UIInterfaceOrientationPortraitUpsideDown) { animatedDistance = floor(PORTRAIT_KEYBOARD_HEIGHT * heightFraction); } else { animatedDistance = floor(LANDSCAPE_KEYBOARD_HEIGHT * heightFraction); } CGRect viewFrame = self.view.frame; viewFrame.origin.y -= animatedDistance; [UIView beginAnimations:nil context:NULL]; [UIView setAnimationBeginsFromCurrentState:YES]; [UIView setAnimationDuration:KEYBOARD_ANIMATION_DURATION]; [self.view setFrame:viewFrame]; [UIView commitAnimations]; } } </code></pre> <p>Now that the view has been 'pushed up' when a <code>UITextField</code> is selected, we want to make sure that we slide it back down when we're done:</p> <pre><code>- (void) textFieldDidEndEditing:(UITextField *)textField { CGRect viewFrame = self.view.frame; viewFrame.origin.y += animatedDistance; [UIView beginAnimations:nil context:NULL]; [UIView setAnimationBeginsFromCurrentState:YES]; [UIView setAnimationDuration:KEYBOARD_ANIMATION_DURATION]; [self.view setFrame:viewFrame]; [UIView commitAnimations]; } </code></pre> <p><a href="http://cocoawithlove.com/2008/10/sliding-uitextfields-around-to-avoid.html" rel="nofollow">This was taken</a> from one of my favorite Cocoa blogs, <a href="http://cocoawithlove.com" rel="nofollow">Cocoa With Love</a>.

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).
