    <p>You DO need to release it. See</p> <p>"As it rebuilds the object hierarchy, however, UIKit reestablishes connections between the objects using the setValue:forKey: method, which uses the available setter method or retains the object by default if no setter method is available." in <a href="http://developer.apple.com/iphone/library/documentation/Cocoa/Conceptual/LoadingResources/CocoaNibs/chapter_3_section_4.html#//apple_ref/doc/uid/10000051i-CH4-SW18" rel="nofollow noreferrer">Nib Object Retention</a> </p> <p>In other words, because you haven't specified these entries as @property (which implicitly declares a setter), or provided a setter directly, there is no available setter method, and the final part of this paragraph applies - the object is retained by default.</p> <p>You should, in your dealloc() method, set all IBOutlets to nil using</p> <pre><code>self.outletName = nil; </code></pre> <p>If no setter is defined, then setValue will autorelease the old value (make sure you have an NSAutoreleasePool if running in a thread). If a setter is defined, it will perform whatever behaviour you defined. Either way, the set to nil will do exactly the right thing, and ensure you get no memory leaks. Do NOT do this</p> <pre><code>outletName = nil; </code></pre> <p>This will directly set the member variable, and bypass calling setValue.</p> <p>See the documentation of NSObject setValue:forKey for more details.</p> <p>Running the Performance Tool (Leaks) will not show a leak, but you can verify that there is actually a leak by looking at the current running total of allocated memory.</p> <p>cf <a href="http://blog.airsource.co.uk/index.php/2008/12/23/memory-management-and-nibs/" rel="nofollow noreferrer">The Airsource - Memory Management and NIBs</a></p>

    1. COself.outletName = nil; No, do *not* do this; you should not use accessor methods in dealloc.

    2. CORe "In other words, because you haven't specified these entries as @property": declaring a property has nothing to do with it. It's the presence or absence of the accessors themselves that's important, not the syntactic sugar.

    3. COAgreed, and edited. My point was that he hadn't declared accessors even by the hidden method of doing it as an @property, but that didn't come across to well.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
