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

When you want a global function, just write a regular C function. The Objective-C syntax is meant to be used solely in the context of object methods.

void printTest() {
    NSLog(@"This is a test");
}

You also have to add the declaration in the functions.h header:

void printTest();
