如何为A Person View Controller的导航栏添加一个返回按钮？

Question

当我显示ABPersonViewController时，我需要一个按钮，允许我将其关闭并返回上一个屏幕。我该如何添加？

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

作为变体：

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:)];
