How to create global functions in Objective-C

Question

I\'m developing an iphone app and I need to have some functions to use globally in my classes.

But how can I do this?

I just tried to create functions.

Answer 1

What your error is referring to is you need to have that method in an interface.

@interface SomeClass
- (void)printTest;
@end

To use a static void throughout your app (where you have included your Functions.h), try the following:

void printTest ()
{
    /* do your print stuff */
}
