Question

When I’m doing a half-page curl modal transition:

How can I tell when the page has been restored back to it’s current state? I want to call something when the “settings” view has been closed.

I tried to use viewWillAppear:(BOOL)animated but it doesn’t seem to get called when closing the view. Any ideas?

You can register an NSNotificationCenter observer on your master view and post the notification on your background view. And instead of viewWillAppear you can use viewDidLoad.

// EDIT: sample code to get a touch gesture in a given rect

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    if ([[event allTouches]count] == 1) {
        UITouch *t = [[touches allObjects]lastObject];
        CGPoint p = [t locationInView:self.view];
        if (p.y < 200) NSLog(@"above 200");
    }
}
