iPhone：選擇一個聯繫人並加載到自定義應用程序

Question

我試圖建立一個應用程序，允許用戶A）輸入一個新的人，或B）從他們的聯繫人中選擇一個人......我的問題是項目B.我簡要地閱讀了關於加載Modal視圖控制器的內容，但是希望有人能夠指導我參考教程或文章的方向，專門討論這種用例場景。

是的，我對iPhone應用程序開發也有點新意。

1. 您的視圖控制器應該實現ABPeoplePickerNavigationControllerDelegate協議
2. 您展現peoplepicker是這樣的：

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; 
}

只是爲了更新每個人（和請糾正我，如果我不當要對這個），我發現這個資源：https://developer.apple.com/library/ios/documentation/ContactData/Conceptual/AddressBookProgrammingGuideforiPhone/index.html
