Nib Object Retention<http://developer.apple.com/mac/library/documentation/Cocoa/Conceptual/LoadingResources/CocoaNibs/CocoaNibs.html#//apple_ref/doc/uid/10000051i-CH4-SW6>
Mac OS X - managed memory model
Objects in the nib file are initially created with a retain count of 1. As
it rebuilds the object hierarchy, however, AppKit autoreleases any objects
that have a parent or owning object, such as views nested inside view
hierarchies. By the time the nib-loading code is done, only the top-level
objects in the nib file have a positive retain count and no owning object.
Your code is responsible for releasing these top-level objects.
Here are my questions:
Who owns the unarchived top-level objects' initial positive retain count?
Are they retained for outlet connections?
Or are they just not autoreleased only because they are top-level,
regardless of whether there are any outlet connected to them?
