I'm having some troubles with my document based app not releasing the
window controller. I've watched the retain and release calls to see
what objects are retaining the controller, but unfortunately, I can't
match up each call to release with each call to retain to tell which
retain isn't getting released. Basically, here's what's happening:
1.) in the Document's makeWindowController method, I allocate the
controller ([[controller alloc] initWithNibName]) which sends a retain
request
2.) I call [document addWindowController]
3.) I manually release the window controller from step 1
4.) in the image controller, I set up a connection between two
threads, which retains/releases 5/6 times
5.) after closing the window, the window sends a few retain/release
calls
and I'm left with a retain count of 1 (and a seriously leaky program).
Do I need to manually remove the controller from the document? I've
noticed that when the document's dealloc method is called, the
windowController array is empty (so I would assume it's automatically
getting removed). If I do need to call removeWindowController:, where
should I do that? I'm also wary of the NSConnection that I create.
Do I need to "close" the connection or anything before I deallocate
it? Anybody have any recommendations?
I can tell you that you don't need to worry about NSConnection. That
class is only used during NIB loading, and the AppKit releases them
when done.
