I have a number of controls with custom bindings that are programmatically added to a view hierarchy in a window. Calling –unbind: on these controls when the window is closes is a challenge.
But it actually does not seem to matter. If –unbind: is never called and the window is closed there are no memory leaks reported in Instruments.
Apple has an undocumented class NSAutounbinder which apparently addresses a problem with retain cycles when binding to File's Owner from a nib file. However I am binding programmatically not inside a nib file. But perhaps NSAutounbinder is somehow working in my behalf.
Is unbinding my programmatic bindings when the window closes something that I should worry about?
