Answer 1

哦，我得到了答案。

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)]; 

Answer 2

爲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:)];
