Objective-C equivalent of Java packages?

Question

What is the Objective-C equivalent of Java packages? How do you group and organize your classes in Objective-C?

Answer 1

What about something like this (inside a directory)?

 #define PruebaPaquete ar_com_oxenstudio_paq1_PruebaPaquete
@interface ar_com_oxenstudio_paq1_PruebaPaquete : NSObject {

and importing it like this:

 #import "ar/com/oxenstudio/paq1/PruebaPaquete.h"
 PruebaPaquete *p = [[PruebaPaquete alloc] init];

and when you have name collision:

 #import "ar/com/oxenstudio/paq1/PruebaPaquete.h"
 #import "ar/com/oxenstudio/paq2/PruebaPaquete.h"


ar_com_oxenstudio_paq1_PruebaPaquete *p = [[ar_com_oxenstudio_paq1_PruebaPaquete alloc] init];
ar_com_oxenstudio_paq2_PruebaPaquete *p2 = [[ar_com_oxenstudio_paq2_PruebaPaquete alloc] init];
