    <p>There's no reason they would reject this. By deprecating the method, <code>-[UIView viewDidUnload]</code> simply becomes like any other method. You can treat it as if it never existed on <code>UIView</code> in the first place and you just happened to create a method called <code>-viewDidUnload</code>.</p> <p>It <em>would</em> be a problem if <code>-viewDidUnload</code> still existed internally (which it might) and you attempted to call Apple's (now private) implementation instead of your own but I highly doubt Apple would do this. Just remember in your <code>-viewDidUnload</code> to remember to ask if the super class implements the method before attempting to call it on super if that's what you're currently doing, using:</p> <pre><code>if ([[self superclass] instancesRespondToSelector:@selector(viewDidUnload)]) { [super viewDidUnload]; } </code></pre> <p>If you really wanted to be safe you could always move your code to a different method. Inside <code>viewDidUnload</code> just call your new method for iOS 5 devices and in <code>-didReceiveMemoryWarning</code> call your new method if you're on iOS 6.</p> <p>I'm not going to comment in length on the logic in your didReceiveMemoryWarning since that wasn't in the question but I will say that you should be very careful about the state you're putting the controller in (make sure those if statements cover all of your bases!) And of course, you cannot expect your view controller and its views to be in the same state when viewDidUnload is called by you as when it was called by UIKit in iOS 5.</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.
