Can i access abPeoplePickerNavigationController's tableview delegate methods?

Can i access abPeoplePickerNavigationController's tableview delegate methods?

I am asking this because i am doing multiple selection (check-marking) in
the abPeoplePickerNavigationController's contacts table-view. But when i
scroll the table-view, all selections are lost. How the check-marks can be
kept intact after scrolling.
Also, I have an global array of names. so when the
abPeoplePickerNavigationController is presented, if a contact first name
matches a name in the array, i want it to be preselected (check-marked) in
the tableview.
I have implemeted uitableview delegate methods like CellForRowAtIndexPath
etc in my class on top of which abPeoplePickerNavigationController is
presented, but they are not called.
