Thanks guys. I basically though that there was a difference between:
@implementation MyClass
int privateVariable;
@end
and
int privateVariable;
@implementation MyClass
@end
the first being being an ivar. The second just being a global.
But IIUC now - there really is no difference. That correct?
Correct.
On a somewhat-related subject, there _is_ a difference between:
@implementation MyClass
void someFunction(/* ... */)
{
/* ... */
}
@end
and:
void someFunction(/* ... */)
{
/* ... */
}
@implementation MyClass
@end
In the former, someFunction is considered to be a part of the
implementation of the class and is permitted to access private and
protected ivars of any MyClass instance it may get its hands on. In
the latter, someFunction has no particular special relationship to
MyClass.
