Re: NSTextView won't deallocate

Sure, I get reference counted memory and it could very well be true that Cocoa has no intent on releasing this at anytime I could expect and that was its design.

If that's true when I would ask WHEN will it be deallocated? I'm leaking memory like crazy allocating these objects and would argue it's bad design on Cocoas part to not give the programmer a reliable way to know when it's memory will be released, as for example we may need to perform some clean up when the object is released.

I wonder why Cocoa has retained it 4 times and what it plans to do with it since I don't see thing that will cause the memory to be released.

Thanks.

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.
