Unfortunately, I can't. ObjectAdded is a callback function (of type
IOServiceMatchingCallback) with a fixed number of parameters.
IOServiceMatchingCallback
Callback function to be notified of IOService publication.
typedef void (*IOServiceMatchingCallback)(
void *refcon,
io_iterator_t iterator );
Parameters
refcon
The refcon passed when the notification was installed.
iterator
The notification iterator which now has new objects.

Unfortunately, it doesn't compile :
error: 'self' undeclared (first use in this function)
Is there a way to achieve what I need ?
Just pass in the object that you want to work with as an argument:
void ObjectAdded(void * refCon, io_iterator_t iterator, FooBar*
myObject)
{
// A lot of things are done...
[myObject addObjectToFooArray:anObject];
}
