I'm looking for a (certainly basic) thing to do in Objective-C/Cocoa : I would like to split my code into multiple files (one for functions, one for tab view N°1 methods, one for tab view N°2 methods, etc) to make my projects well organized.

I would like to be able to call functions and/or methods from my "AppDelegate.m".

But I don't know how to formulate this question correctly to find help around the web. I come from Delphi, and in Delphi you have just to create a new .PAS file and declare it in USES section.

We are in 2013, so it's certainly an ultra-basic way to code properly via XCode :)

Thanks in advance for any help.

  • Ah ! So, I would to put all my functions (for string manipulations for example) in another file. Then, from my main "AppDelegate.m" I'll call these functions. Commented Jan 5, 2013 at 17:06
  • Now that it seems easy, I'm sure I'll get some downvotes... :D Commented Jan 5, 2013 at 17:53

Basically, it's the same - except with the C background of Objective-C you will have to create 4 files. Two header files (.h) and two implementations (.m).

Instead of the uses section you will use the #import statement at top of the .m files.

#import "myClassHeader.h"

As this belongs to the more basic tasks in Objective-C or any C-based language, you should start with reading some beginners tutorial, how to define classes and methods.

Thanks for your reply ! Ah ok, so I just tried that. I created a new class MyFunctionName(.h and .m). In AppDelegate.m I called #import "MyFunctionName.h". In MyFunctionName.m I created a basic function - (void)myExample:(NSString *)Value { NSLog(Value); }. Now, I would to be able to call it from AppDelegate.m.
It seems that my question correspond to this one in reality : stackoverflow.com/questions/3572448/… I'm trying to make some tests and come back then.
Ok cool. It was that ! I didn't find anything about MyFunctionName *myScript = [[MyFunctionName alloc] init]; before, so I didn't know how to call the function or method from 2nd class. But creating a new class was well the solution to separate my long code into small differents classes, well organized.
