Is it possible to get the total number of items defined by an enum at runtime?
While it's pretty much the same question as this one, that question relates to C#, and as far as I can tell, the method provided there won't work in Objective-C.

Using preprocessors you can achieve this without the annoying 'hack' of adding an additional value to your enum
#define __YourEnums \
YourEnum_one, \
YourEnum_two, \
YourEnum_three, \
YourEnum_four, \
YourEnum_five, \
YourEnum_six,
typedef enum : NSInteger {
__YourEnums
}YourEnum;
#define YourEnum_count ({ \
NSInteger __YourEnumsArray[] = {__YourEnums}; \
sizeof(__YourEnumsArray)/sizeof(__YourEnumsArray[0]); \
})
