I had to declare the objects as pointers and allocate them memory in
the program
eg:
object *obj (in the first class)
[obj alloc....];(class 1)
object *obj2 (in the second class)
obj2 = [outlet getObject];
all i want is for obj2 to point to the same object as obj.

To get the address of a variable, use &obj. Are you sure that's what
you want to do? If obj is a pointer to an Objective-C object, such as
in 'NSDictionary * obj;' , then it is already a pointer to an object.
You should be able to return it normally with 'return obj;'
object obj;
//...
-(object *) function:(id)sender
{
return &obj;
}

decleration:
- (object *) function:(id)sender;
implementation:
-(object *) function:(id)sender
{
return *obj;
}
call:
obj2 = [outlet function];
what am i doing wrong ? Thanks.
