iOS Delegation in iOS The Delegate Pattern Acting As A Delegate

How do we assign multiple delegates?

The problem outlined in this video series was that a Race might need to be monitored by both a Tracker AND a RaceBroadcaster (perhaps with even a few more objects listening as well), but it appears that we can only assign a single delegate at a time, so while this decouples the code - it doesn't actually solve the problem of having the events sent to multiple objects.

Is there a way to assign multiple delegates?

The delegate protocol pattern is used for a one to one communication, not a one to many. If you want a one to many communication you should use the Observer & Notification Pattern. I got a better explanation from the youtube video’s below:

Thank you for your help Franklin!

rickketter asked a very good question, because the same question came to my mind... And Franklin provided a very good explanation.. Thanks both of you
