isBeingDismissed not set in viewWillDisappear:

Question

I have some code to clean up in my viewWillDisappear:, which I only want to use when the view is moving back to the parent view controller.

- (void)         


        

Answer 1

If this is the first view controller in a modal navigation controller that's being dismissed, calling self.isBeingDimissed() from viewWillDisappear: returns false.

However, since the entire navigation controller is being dismissed, what actually works is self.navigationController?.isBeingDismissed(), which returns true.
