Enum as a class property in Objective-C

For this post I'd like to show how you can define an enum property in Objective-C.

In a nutshell an enum is a datatype you create where in theory only certain values can be assigned to it and none else.

The code is pretty straight forward. Here it goes:

typedef enum

{

North, South, East, West

} Direction;

@interface MyClassName : NSObject

{

Direction direction;

}

@property(nonatomic) Direction direction;

In the above example only the values North, South, East, and West can be assigned to the direction property of a MyClassName instance.
