Re: NSWindowController and window release

Graham Cox

OK, I figured it out.

What was important to me was that the custom view was deallocated. Therefore it was the view’s -dealloc I was logging, not the window’s. I inferred, incorrectly, that it was the window that wasn’t going away. In fact it was, but the view wasn’t.

The custom view is set up as a layer hosting view, and I set the view to be the layer’s -layoutManager. That’s a strong property, so a retain cycle was created there.

Once understood, easily solved.

I do vaguely recollect something about this possibility in documentation a long time ago, but going through it just now, could find no mention of it. In the end, the only canonical documentation is the headers. Ho hum.
