Question

I have two views with their controllers.
The application start with the FirstViewController.
Then with a button I open the SecondViewController.

With other button I dismiss the SecondViewController to return to FirstViewController.

Is there any way to detect that in FirstViewController that it has recovered focus?

EDIT: Ok I look the answers and I use viewWillAppear but don’t work if I use a UIModalPresentationFormSheet.

-(IBAction)openSecondView{
    SecondViewController *screen = [[SecondViewController alloc] initWithNibName:nil bundle:nil];
    screen.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
    screen.modalPresentationStyle = UIModalPresentationFormSheet;
    [self presentModalViewController:screen animated:YES];
    [screen release];
}

And close this view with close button.

viewWillAppear never called.

Answer 1

Add a delegate (Protocol) method. Call the delegate method just before dismissing the SecondViewController.
