self.tabBarController.selectedIndex = 0;
[self.navigationController popViewControllerAnimated:YES];
this then causes the ViewController A to be visible.
But how do I then get ViewController B to fire an action on A?
I have tried to use:-
ViewControllerA *aVC = ((ViewControllerA *)((UIViewController *)[self.tabBarC.tabBarController.viewControllers objectAtIndex:0]));
[aVC setAnnoSelected];
Only when I do that I get:-
-[UINavigationController setAnnoSelected]: unrecognized selector sent to instance 0x461d290
I have tried to use
[ViewControllerA performSelector:@selector(setAnnoSelected) withObject: nil afterDelay: 0.0];
But so far no joy.
Any ideas would be greatly appreciated.
Thanks
Cheryl
