iOS ABPersonViewController

Question

我有一个选项卡栏应用程序，在第一个选项卡中，我有一些按钮和一个表格视图，其中填充了地址簿的联系信息。当点击单元的附件按钮时，我尝试使用ABPersonViewController作为模式视图来显示联系信息。我可以显示联系信息，但没有取消按钮来解除模式视图。谁能看看下面的代码，让我知道我错过了什么。

ABRecordRef person = (ABRecordRef)[[self peopleList] objectAtIndex:[indexPath row]];
if (ABRecordGetRecordID(person) != kABRecordInvalidID)
{
    ABPersonViewController *personViewController = [[ABPersonViewController alloc] 
                           init];
   personViewController.displayedPerson = person;
    personViewController.allowsActions = YES;
   personViewController.navigationItem.title=@"Contact Info";   
   UINavigationController *navigationController = 
            [[UINavigationController alloc]initWithRootViewController:personViewController];
    [self presentModalViewController:navigationController animated:YES];
    [personViewController release];
}      

Answer 1

根据docs的说法，“人员视图控制器必须与导航控制器一起使用，才能正常工作。”

ABPersonViewController *personViewController = [[ABPersonViewController alloc] init];
personViewController.personViewDelegate = self;
personViewController.displayedPerson = person;
personViewController.allowsAction = YES;
personViewController.navigationItem.title=@"Contact Info";

UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:personViewController];

[self presentViewController:navController animated:YES completion:NULL];
