从地址簿中获取两个文本字段的电话号码

Question

我按照Apple Address Book Programming Guide for iOS 来获取地址簿中的电话号码到UITextField。但我有两个UITextField，并且不知道如何在第二个文本字段中实现相同的功能。

介绍人员选择器

- (IBAction)showPicker:(id)sender

{

    ABPeoplePickerNavigationController *picker =

            [[ABPeoplePickerNavigationController alloc] init];

    picker.peoplePickerDelegate = self;



    [self presentModalViewController:picker animated:YES];

}

响应人员选择器中的用户操作

- (void)peoplePickerNavigationControllerDidCancel:

            (ABPeoplePickerNavigationController *)peoplePicker

{

    [self dismissModalViewControllerAnimated:YES];

}





- (BOOL)peoplePickerNavigationController:

            (ABPeoplePickerNavigationController *)peoplePicker

      shouldContinueAfterSelectingPerson:(ABRecordRef)person {



    [self displayPerson:person];

    [self dismissModalViewControllerAnimated:YES];



    return NO;

}



- (BOOL)peoplePickerNavigationController:

            (ABPeoplePickerNavigationController *)peoplePicker

      shouldContinueAfterSelectingPerson:(ABRecordRef)person

                                property:(ABPropertyID)property

                              identifier:(ABMultiValueIdentifier)identifier

{

    return NO;

}

显示某人的信息

- (void)displayPerson:(ABRecordRef)person

{

    NSString* name = (__bridge_transfer NSString*)ABRecordCopyValue(person,

                                               kABPersonFirstNameProperty);

    self.firstName.text = name;



    NSString* phone = nil;

    ABMultiValueRef phoneNumbers = ABRecordCopyValue(person,

                                    kABPersonPhoneProperty);

    if (ABMultiValueGetCount(phoneNumbers) > 0) {

       phone = (__bridge_transfer NSString*)

               ABMultiValueCopyValueAtIndex(phoneNumbers, 0);

    } else {

        phone = @"[None]";

    }

    self.phoneNumber.text = phone;

}

修改

- (void)displayPerson:(ABRecordRef)person

{

    NSString* phone = nil;

    ABMultiValueRef phoneNumbers = ABRecordCopyValue(person, kABPersonPhoneProperty);

    if (ABMultiValueGetCount(phoneNumbers) > 0) {

        phone = (__bridge_transfer NSString*)

        ABMultiValueCopyValueAtIndex(phoneNumbers, 0);

    } else {

        phone = @"None";

    }


    self.phoneNumber.text = phone;



    if (ABMultiValueGetCount(phoneNumbers) > 1) {

        phone = (__bridge_transfer NSString*)

        ABMultiValueCopyValueAtIndex(phoneNumbers, 1);

    } else {

        phone = @"None";

    }

    self.phoneNumber2.text = phone;


}

Answer 1

我假设您的第二个UITextField是第二个电话号码（如果存在）？然后你可以这样做：

if (ABMultiValueGetCount(phoneNumbers) > 1) {
   phone = (__bridge_transfer NSString*)ABMultiValueCopyValueAtIndex(phoneNumbers, 1);
} else {
    phone = @"[None]";
}

self.phoneNumber2.text = phone;

或者您可以使用CFBridgingRelease代替__bridge_transfer：

phone = CFBridgingRelease(ABMultiValueCopyValueAtIndex(phoneNumbers, 1));

而且，顺便说一下，您是否也想使用ABMultiValueCopyLabelAtIndex来捕获每个电话号码的类型（如果您不知道什么，它无助于知道电话号码是什么它的数字类型）。您可以将这两个电话号码标签存储在另外两个UITextField中（可能是在各自的电话号码旁边）。

<强>更新

我原本以为你在寻找同一个联系人的两个电话号码。我现在从您的用户界面推断，您要在按钮上点击两个电话号码文本字段旁边的“+”按钮，然后拉出该文本字段的电话号码。然后，您可以点击其他文本字段旁边的“+”按钮，然后提取其他联系人的电话号码并将其放在该文本字段中。

因此，如果是这种情况，您可以在班级中添加一个ivar，例如：

int _phoneNumberIndex;

然后第一个“+”按钮会有一个IBAction，如：

- (IBAction)showPicker1:(id)sender
{
    ABPeoplePickerNavigationController *picker = [[ABPeoplePickerNavigationController alloc] init];

    picker.peoplePickerDelegate = self;

    _phoneNumberIndex = 1;

    [self presentModalViewController:picker animated:YES];
}

而第二个“+”按钮会有IBAction之类的：

- (IBAction)showPicker2:(id)sender
{
    ABPeoplePickerNavigationController *picker = [[ABPeoplePickerNavigationController alloc] init];

    picker.peoplePickerDelegate = self;

    _phoneNumberIndex = 2;

    [self presentModalViewController:picker animated:YES];
}

然后你的displayPerson会是这样的：

- (void)displayPerson:(ABRecordRef)person
{
    // first name

    NSString* name = CFBridgingRelease(ABRecordCopyValue(person, kABPersonFirstNameProperty));

    self.firstName.text = name;

    // phone numbers

    NSString* phone;

    ABMultiValueRef phoneNumbers = ABRecordCopyValue(person, kABPersonPhoneProperty);

    // first phone number

    if (ABMultiValueGetCount(phoneNumbers) > 0)
        phone = CFBridingRelease(ABMultiValueCopyValueAtIndex(phoneNumbers, 0));
    else
        phone = @"[None]";

    if (_phoneNumberIndex == 1)
        self.phoneNumber.text = phone;
    else if (_phoneNumberIndex == 2)
        self.phoneNumber2.text = phone;
    else
        NSLog(@"Unrecognized _phoneNumberIndex");

    CFRelease(phoneNumbers);
}

顺便说一下，虽然我认为这可以满足您的需求，但是您不清楚应该使用名字字段做什么（因为您选择了两个联系人，您想要使用的是第一个名字，或者你会将两个名字存储在两个字段中，就像你使用电话号码一样？）。所以，你必须要看一下。

显然，如果您不想为两个“+”按钮使用两个IBAction方法，那么您可能只需要查看sender或其标记的单个方法，但这并不重要你的问题。最后一行，使用ivar指定您要更新的电话号码。
