In Objective-C, the 'retain' message increases the retain count of an object by 1, meaning that you are telling the object to hold on to its memory a little longer. The 'assign' message simply sets a new value for an object without increasing or decreasing its retain count. It is used with primitive types like NSNumber and NSString.
