ios - ABPersonViewController does not have a navigationBar -

i writing application based on uiviewcontroller. not have navigation bar. application works addressbook. use 2 things.

the first (select people):

{     abpeoplepickernavigationcontroller *picker = [[abpeoplepickernavigationcontroller alloc] init];     picker.peoplepickerdelegate = self;     [self presentmodalviewcontroller:picker animated:yes]; } 

and second (select phone):

{     abpersonviewcontroller *picker = [[[abpersonviewcontroller alloc] init] autorelease];     picker.personviewdelegate = self;     picker.displayedperson = person;     picker.displayedproperties = [nsarray arraywithobjects: [nsnumber numberwithint:kabpersonphoneproperty], nil];     [self presentmodalviewcontroller:picker animated:yes]; } 

they called in different functions.

in first case when picker displayed, has navigation bar buttons: cancel etc.

in second case picker not have navigation bar. so, if select phone works if want return without making choice - not have button "back" or "cancel".

how can add navigation bar in second case?
