Remarks
In iOS 6 and later, UIView's that are referenced by live objects are not scavenged during low-memory situations. In other words, in iOS 6 and later, this method is never called. In previous versions, application developers may override this method to ensure that all references to the scavenged View have been removed. When this method is called, View is null.
