检查value是否为整数（Objective-C）

Question

How do I check if my value is a integer or not?
I want something like this:

if ( i/split != int )  {...}

Thanks,

Answer 1

I'm not sure but I think you're trying to find out if the result of the divide is a whole number. You can use modulus operator % to get the remainder from the divide operation.

Assuming i and split are integer types (int, long, short, etc), then modulus returns 0 when i or split is an integer value, ie:

if ( i % split == 0 ) {...}

Answer 2

Just use the objCType method? Docs
