HI, someone said to me that *@class* directive create a new instance of the
class automatic. I tried to find information about this, but didn't found.
For me, @class is only to solve cyclic includes. There are any side effect
using it? The object variable is the same in this 2 example below, or there
are some difference? The instance *instanceMyClass* will be the same of the
class that send the pointer, right? And I will not lose any memory right?
Example 1
//in sample.h
#include "myClass.h"
myClass *instanceMyClass;
//in sample.m
#include "sample.h"
-(id) initWithMyClass :(myClass *) linkMyClass {
instanceMyClass = linkMyClass;
}
Example 2
//in sample.h
@class myClass;
myClass *instanceMyClass;
//in sample.m
#include "sample.h"
#include "myClass.h"
-(id) initWithMyClass :(myClass *) linkMyClass {
instanceMyClass = linkMyClass;
}
