Answer Posted / Mahfooz Alam
In Objective-C, a protocol defines a blueprint of methods that a class should implement to adhere to certain rules or behaviors. It is a way for multiple classes to communicate with each other by following a common interface. On the other hand, a delegate is an object that is appointed to handle specific events or tasks for another object. A delegate typically conforms to a protocol to define the methods it will implement.
