Monotouch: Right manner for using NSNotificationCenter

Question

What's the right manner to use NSNotificationCenter?

I would know if there is a sort of guideline to register and remove observers in a specific class.

NSNotificationCenter.DefaultCenter.AddObserver("NSString", Action)

is used to register an object as an obsever. How can I deregister an observer? Do I have to save all the observer for a specific class in arrays?

Thank you in advance. Regards.

Answer 1

The AddObserver method returns an object of type NSObject.

So you call it like this:

NSObject myObserver = NSNotificationCenter.DefaultCenter.AddObserver("NSString", Action);

And when you want to remove it, call the following:

NSNotificationCenter.DefaultCenter.RemoveObserver(myObserver);
