Question

I have a class that creates a calendar. One of the methods finds the date the user tapped, and stores it in a CFGregorianDate object in that same class.

I have a need to know in another class when the user tapped the calendar date, but after the CFGregorianDate object has been updated, so I can do some backend processing.

How do I get notification of the tap in the second class?

Answer 1

consider NSNotificationCenterClass an option for you..

 // add this in your anotherClass
 [[NSNotificationCenter defaultCenter] removeObserver:self];
 [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(objectUpdated:) name:@"objectUpdated" object:nil];



 //then post notification after you updated the CFGregorianDate
 NSNotificationCenter *ncSubject = [NSNotificationCenter defaultCenter];  
 [ncSubject postNotificationName:@"objectUpdated" object:nil];  
 [ncSubject removeObserver:self];
