Can I use an enum as a property in Objective C

Question

I saw it is customed to use a boolean property as a flag. something like that:

@property (nonatomic) BOOL commaAlreadyIntroduced; 

I need something like that but with at least 3 or 4 states.

Can I use an enum?

The standalone enum should look like:

typedef enum stackState{     empty, oneOperand, operandAndOperator, fullStack }stackState; 

Answer 1

Yes, it's not a problem:

@property (nonatomic, assign) stackState yourIvar; 

Answer 2

@property (nonatomic, assign) enum stackState stackStateVar; 

Without 'enum' added, my unit tests kept showing errors.
