Maybe I am missing something, but given your example - which in some sense contradicts your comment, why do you expect dealloc to be called?
If the retain count is in fact > 0 after the release (4 in your example below) dealloc is not called, since the view can not yet be deallocated.
View.release just means "*I* (i.e. the caller) don't care about you any longer". But if some other object still cares (i.e. the retain count > 0, as in your example), dealloc won't be called. In short: release != dealloc. Or the other way round: only after x retains are balanced by the same number of release messages, dealloc eventually will be called by the runtime and the object is finally cleaned up and purged from memory.
Sorry if I am getting you wrong and point out the obvious ...

I know the retainCount doesn't tell the whole story and it may be retained by other objects (rightfully so) but then WHEN will it be released if not when I request it to? I must be missing something... Thanks!
