ios - 地址簿链接器错误 : Undefined symbols for architecture i386

当我使用 __bridge_transfer 或 __bridge 时:

- (BOOL)peoplePickerNavigationControllerABPeoplePickerNavigationController *)peoplePicker
      shouldContinueAfterSelectingPersonABRecordRef)person 
{
    NSString* nameFirst = (__bridge_transfer NSString *)ABRecordCopyValue(person,
                                                   kABPersonFirstNameProperty);       
    NSString* nameLast = (__bridge_transfer NSString *)ABRecordCopyValue(person, kABPersonLastNameProperty);
    _sight.contactName = [NSString stringWithFormat"%@ %@", nameFirst, nameLast];

    [self dismissModalViewControllerAnimated:YES];
    return NO;
}

上面的代码产生下面的错误:

Addressbook 和 AddressbookUI 框架添加...

好的，问题是地址簿框架在我的项目中，但从“项目”-“摘要选项卡”-“链接的框架和库”中消失了。

添加框架后，所有问题都消失了。
