    <p>My current solution is to manually adjust the layer's position in <code>viewDidLayoutSubviews</code>. This code could also be used in <code>layoutSubviews</code> for a view subclass, but in my case my view is a top-level view inside a view controller, so this meant I didn't have to make a UIView subclass. </p> <p>It seems like too much effort so other answers are most welcome. </p> <pre><code>-(void)viewDidLayoutSubviews { for (UIView *view in self.view.subviews) { CGPoint anchorPoint = view.layer.anchorPoint; // We're only interested in views with a non-standard anchor point if (!CGPointEqualToPoint(CGPointMake(0.5, 0.5),anchorPoint)) { CGFloat xDifference = anchorPoint.x - 0.5; CGFloat yDifference = anchorPoint.y - 0.5; CGPoint currentPosition = view.layer.position; // Use transforms if we can, otherwise manually calculate the frame change // Assuming a transform is in use since we are changing the anchor point. if (CATransform3DIsAffine(view.layer.transform)) { CGAffineTransform current = CATransform3DGetAffineTransform(view.layer.transform); CGAffineTransform invert = CGAffineTransformInvert(current); currentPosition = CGPointApplyAffineTransform(currentPosition, invert); currentPosition.x += (view.bounds.size.width * xDifference); currentPosition.y += (view.bounds.size.height * yDifference); currentPosition = CGPointApplyAffineTransform(currentPosition, current); } else { CGFloat transformXRatio = view.bounds.size.width / view.frame.size.width; if (xDifference &lt; 0) transformXRatio = 1.0/transformXRatio; CGFloat transformYRatio = view.bounds.size.height / view.frame.size.height; if (yDifference &lt; 0) transformYRatio = 1.0/transformYRatio; currentPosition.x += (view.bounds.size.width * xDifference) * transformXRatio; currentPosition.y += (view.bounds.size.height * yDifference) * transformYRatio; } view.layer.position = currentPosition; } } } </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.
