Question

Okay, I understand how to work delegation in a modal view to send a message to the parentviewcontroller but what if I wanted to do that with 2 views that dont have that parent-child relationship?

I have a navigation controller that flips over a modal view and then that modal view pushes a new view controller. How do I let that pushed view controller talk to the navigation controller. The modal view code that I have been using places this in the parent:

-(IBAction)pressedUnitAddy {
UnitAddyView *unitVC = [[UnitAddyView alloc] init];

unitVC.delegate = self;

UINavigationController*  theNavController = [[UINavigationController alloc]initWithRootViewController:unitVC];

theNavController.modalTransitionStyle = UIModalTransitionStylePartialCurl;
[self presentModalViewController:theNavController animated:YES];

[unitVC release];
[theNavController release];

}

-(void)didDismissUnitAddyView {
[self dismissModalViewControllerAnimated:YES];
}

….and then I call the didDismissUnitAddyView from the UnitAddyView. Now, I am not trying to dismiss any views with what I am trying to do but I do want that pushed view controller to be able to speak to the navigation controller. How would I do that?

All I was trying to do was to reload the data on the nav controller screen. The UIViewController and the nav controller we not directly connected – they were separated through a modalview. All I did, and I should have thought of this earlier, was set the modal view’s delegate to the nav controller and to call a method to reload the nav controller when the modal view is dismissed.
