Question

Having

enum {MyA, MyB, Null};
typedef NSNumber myEnum;

Or

typedef enum {MyA, MyB, Null} myEnum;

1) How do I create an array

myEnum* myEnumTemp[] = {MyA, MyB};

Just gives "Implicit conversion of 'int' to NSNumber* is disallowed with ARC(ref. counting)

2) If you are able to create an array how to convert it to NSArray?

Answer 1

Try to do it this way :

typedef enum { MyA, MyB, Null } myEnum;

Then, to create an array, wrap the numbers into NSNumbers objects :

NSArray *a = [NSArray arrayWithObjects:[NSNumber numberWithInteger:MyA],
                                       [NSNumber numberWithInteger:MyB],
                                       nil];
