As others stated, "[self release];" is a valid instruction, and can be
useful.
Two remarks related to your situation:
- Instead of releasing your controller in windowShouldClose:, do it in
windowWillClose:. Generally, you can't be sure that your window will
really be closed until you receive the windowWillClose: message. In
addition, doing this kind of cleanup in windowWillClose: better shows
your intent.
- You must determine if, in your particular situation, the "[self
release]" might lead to the immediate deallocation of your controller
(when looking at this, take into consideration the fact that windows
do not retain their delegates). If so, you must make sure that your
controller instance will no more be used after its deallocation. In
particular, you must ensure that the window will no more message your
controller (its delegate). A good way to ensure that is for you
controller to stop being the window's delegate before releasing
itself.
Your windowWillClose: method might look like this:
- (void)windowWillClose:(NSNotification *)aNotification
{
[[aNotification object] setDelegate:nil];
[self release];
}
Best,
