Pass Data back to parentView: isMovingToParentViewController not working?

Question

I implemented a navigation controller in my iPad app which works perfectly fine.

Now, on one view of the navigation stack I want to pass data to the parent view if popped to it.

I tried this in the child view controller:

(property of dataArray +synthesize in both views)

-(void)viewWillDisappear:(BOOL)animated
{

if([self isMovingToParentViewController])
{
int currentVCIndex = [self.navigationController.viewControllers indexOfObject:self.navigationController.topViewController];

ParentViewController *parent = (ParentViewController *)[self.navigationController.viewControllers objectAtIndex:currentVCIndex];

parent.dataArray = self.dataArray;
}


}

Any Ideas why not working?

why not holding a permanent reference to the parent view? Otherwise I recomand a protocol methode for a "callback" http://stackoverflow.com/questions/16584930/objective-c-accessing-methods-from-custom-cell/16585079#16585079 — geo, May 25 '13 at 18:13

It is working when using isMovingFromParentViewController instead of isMovingToParentViewController.

That doesn't make any sense to me at all.

Ok. It seems isMoving has nothing to do with the navigation stack at all. Even when using [self.navigationController isMovingToParentVC], it's only saying that it's moving, to whatever view.
