How to add a return button for ABPersonViewController's navigationbar?

When I display an ABPersonViewController, I need a button that allows me to di开发者_StackOverflow社区smiss it and return to the previous screen. How do I add this?

Oh, I got the answer.

ABPersonViewController *personViewController = [[ABPersonViewController alloc] init];
personViewController.addressBook = addr;
personViewController.displayedPerson = ABAddressBookGetPersonWithRecordID(addr, (ABRecordID)personID);
personViewController.allowsEditing = YES;
personViewController.personViewDelegate = self;     
personViewController.navigationItem.backBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:NSLocalizedString(@"Return",nil) style:UIBarButtonItemStylePlain target:self action:@selector(ReturnFromPersonView)];

As variant:

ABPersonViewController *personView = [[ABPersonViewController alloc] init];
[self.navigationController pushViewController:personView animated:YES];
personView.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"return" style:UIBarButtonItemStyleBordered target:self action:@selector(action:)];
