    copied!<p>I did some debugging and here's what I found about the <code>ViewController</code> loading order:</p> <pre><code>initWithNibName:bundle: self = &lt;original instance&gt;, retainedOutlet = 0x0 loadView &gt;&gt;&gt; self = &lt;original instance&gt;, retainedOutlet = 0x0 initWithCoder: self = &lt;coder instance&gt;, retainedOutlet = 0x0 initWithCoder: self = &lt;coder instance&gt;, retainedOutlet = 0x0 setView: self = &lt;original instance&gt;, retainedOutlet = 0x0 setRetainedOutlet: self = &lt;original instance&gt;, retainedOutlet = 0x1613c40 viewDidLoad self = &lt;coder instance&gt;, retainedOutlet = 0x0 awakeFromNib self = &lt;coder instance&gt;, retainedOutlet = 0x0 loadView &lt;&lt;&lt; viewDidLoad self = &lt;original instance&gt;, retainedOutlet = 0x1613c40 viewWillAppear: self = &lt;original instance&gt;, retainedOutlet = 0x1613c40 dealloc self = &lt;coder instance&gt;, retainedOutlet = 0x0 viewDidAppear: self = &lt;original instance&gt;, retainedOutlet = 0x1613c40 </code></pre> <p>During the loadView method, <code>initWithCoder:</code> is called and a new copy of the <code>viewController</code> is created. this is what is passed into a few of the methods (like <code>viewDidLoad</code>). the copy is destroyed later in a dealloc call. the good news is that in this copy, retained outlets are not configured, so you can use this as a test to know if you should initialize variables, call other methods, and most importantly, if you should release and destroy objects during dealloc.</p> <p>Key takeaway: the real <code>viewController</code> will have its retained <code>IBOutlet</code> properties configured. if you are in an overridden method that is getting called multiple times, just check one of your retained <code>IBOutlet</code> properties for <code>NULL</code>. if they are <code>NULL</code>, then return immediately.</p> <p>Anybody got any clues as to why this is happening this way?</p> <p>Side effect of this: you can't use <code>awakeFromNib</code> reliably.</p>
