I have a view which contains scroll view with some subviews (UIViewControllers). I want to call a method (stop timer) from a class, one of their UIViewControllers, in applicationWillResignActive: method of App Delegate.
What's the best way to implement this?
Don't worry about handling that event in your app delegate and passing it on. Just register for a notification in whatever class you're interested in handling the event from:
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(someMethod:)
name:UIApplicationWillResignActiveNotification
object:nil];
