Objective C: convert string to enum

Question

If I have an enum:

typedef enum {
  SOMETHING,
} MyEnum

and I have a NSString "SOMETHING", is there a way I can go directly from the string to the ENUM value? I realize I can just make a dictionary to do this, but I'm curious.

There isn't really a clean way to do this in Objective-C (or C, for that matter).

You're going to have to map the enum values to their string counterparts. There are a number of ways you can do this: (1) A dictionary, as you mentioned. (2) A switch statement. (3) An array of string values where each index maps to a the corresponding enum value.

FYI... switch statements in Objective-C can only operate on integer types. You would have to use an if...else if... construct.
