iOS - Best practice for handling network response cross ViewControllers

For example, There are 3 sequencial view controllers, A, B, C, in the navigation stack. After sending an async network request in view controller C in the background thread, User may go back to B or A.

What is the best way to handle the network response no matter where the current view controller is?

Thanks.

Since the three view controllers may be interested in the response, don't make it in any of them. Create a class, let's say NetworkHandler with method - (void) makeRequest. You can make it a singleton or add it to the AppDelegate.

In C, call this method.

When - (void) makeRequest finishes the call, make an NSNotification and make all three view controllers register to this notification.

It is better to have a Singleton class. You can have some delegate also to notify the controller that response received and do the respective action.
