If you've recently gotten a memory warning, then this image view is either nil, or will be released very soon, and you will end up with a view that has no image.

So let's say I have a view controller. And let's say that its view (self.view) contains a UIImageView in its hierarchy (self.view.imageview). You are saying that the runtime might summarily rip the UIImageView out of the interface, so that self.view is *not* nil but self.view.imageview *is* nil???
