Question

How large number can I use for enum in Objective-C?
Same as NSInteger?

typedef enum {
    myEnumA = -1000,
    myEnumB = 1000,
    myEnumC = 2000
} myEnum;

Answer 1

Since ObjC is based on C, you’ll probably find it matches the standard for that language:

From:

• c90 3.5.2.2 Enumeration specifiers ^(a)
• c99 6.7.2.2 Enumeration specifiers
• c11 6.7.2.2 Enumeration specifiers

The expression that defines the value of an enumeration constant shall be an integer
constant expression that has a value representable as an int.

^(a): C90 actually says “integral” rather than “integer” but it means the same thing.
