Question

I want to define a min and max methods in a Utils class.

@interface Utils

int min(int a, int b);
int max(int a, int b);

@end

But I don’t want to have named parameters. It would be a too heavy notation. I wanted to use the C-style definition. But then [Utils min(a, b)] as a call doesn’t work. What is my problem?

Thanks in advance for any help

Since you aren’t using the OS X Implementation of objective-c, you may not have access to the predefined MIN and MAX macros.

You can define these yourself as

#define MIN(a,b)    ((a) < (b) ? (a) : (b))
#define MAX(a,b)    ((a) > (b) ? (a) : (b))

There is probably a better way to define them, but these will create the simple macros for your use. You can add them into any common .h file that your classes normally share.
