iPhone：选择一个联系人并加载到自定义应用程序

Question

我试图建立一个应用程序，允许用户A）输入一个新的人，或B）从他们的联系人中选择一个人......我的问题是项目B.我简要地阅读了关于加载Modal视图控制器的内容，但是希望有人能够指导我参考教程或文章的方向，专门讨论这种用例场景。

是的，我对iPhone应用程序开发也有点新意。

1. 您的视图控制器应该实现ABPeoplePickerNavigationControllerDelegate协议
2. 您展现peoplepicker是这样的：

ABPeoplePickerNavigationController *peoplePickerController = 
    [[ABPeoplePickerNavigationController alloc] init]; 
    peoplePickerController.peoplePickerDelegate = self; 

    [self presentModalViewController:peoplePickerController animated:YES]; 

    [peoplePickerController release]; 

3. And you might want to implement the optional methods as: 

- (void)peoplePickerNavigationControllerDidCancel:(ABPeoplePickerNavigationController *)peoplePicker 
{ 
    [self dismissModalViewControllerAnimated:YES]; 
} 

- (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person 
{ 
    NSString *name = (NSString *)ABRecordCopyCompositeName(person); 
    // do something with name.. and release 

    [self dismissModalViewControllerAnimated:YES];  

    return NO; 
} 

- (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier 
{ 
    return NO; 
}

只是为了更新每个人（和请纠正我，如果我不当要对这个），我发现这个资源：https://developer.apple.com/library/ios/documentation/ContactData/Conceptual/AddressBookProgrammingGuideforiPhone/index.html
