If you don't retain a top-level NIB object in iOS, sooner or later it _won't_ exist. They are retain/autoreleased upon load, and if there is no strong reference, they get deallocated.
See <http://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/LoadingResources/CocoaNibs/CocoaNibs.html> and search for "Managing Nib Objects in iOS."
