多值url地址簿iphone

我想在通讯簿中创建一个新联系人。 当您想存储更多URL（某些社交网络的网址）时，就会出现问题。 我的代码在iOS6模拟器中工作得非常好。但在真正的iPhone中，iOS6存储了所有的值​​除了网址。 我已经找了几天了，找不到解决办法，如果有人能帮忙，我将非常感激

我的代码：

-(void) addContactToAddressBook:(ABAddressBookRef) iPhoneAddressBook 
{

    CFErrorRef error = NULL;

    ABRecordRef newPerson = ABPersonCreate();

    //Name and phone number
    ABRecordSetValue(newPerson, kABPersonFirstNameProperty, (__bridge CFStringRef)_nameField.text, &error);
    ABMutableMultiValueRef multiPhone = ABMultiValueCreateMutable(kABMultiStringPropertyType);
    ABMultiValueAddValueAndLabel(multiPhone, (__bridge CFStringRef)_phoneField.text, kABPersonPhoneMainLabel, NULL);
    ABRecordSetValue(newPerson, kABPersonPhoneProperty, multiPhone,nil);

    //Email value
    ABMutableMultiValueRef emailMultiValue = ABMultiValueCreateMutable(kABMultiStringPropertyType);
    ABMultiValueAddValueAndLabel(emailMultiValue, (__bridge CFStringRef)_emailField.text, kABWorkLabel, NULL);
    ABRecordSetValue(newPerson, kABPersonEmailProperty, emailMultiValue, nil);
    CFRelease(emailMultiValue);

    //URL values
    ABMutableMultiValueRef urlMultiValue = ABMultiValueCreateMutable(kABMultiStringPropertyType);
    ABMultiValueAddValueAndLabel(urlMultiValue, (__bridge CFStringRef)_FacebookField.text, (CFStringRef)@"Facebook", NULL);
    ABMultiValueAddValueAndLabel(urlMultiValue, (__bridge CFStringRef)_twitterField.text, (CFStringRef)@"Twitter", NULL);
    ABMultiValueAddValueAndLabel(urlMultiValue, (__bridge CFStringRef)_linkedinField.text, (CFStringRef)@"Linkedin", NULL);
    ABMultiValueAddValueAndLabel(urlMultiValue, (__bridge CFStringRef)_googleField.text, (CFStringRef)@"Google+", NULL);
    ABRecordSetValue(newPerson, kABPersonURLProperty, urlMultiValue, nil);
    CFRelease(urlMultiValue);

    ABAddressBookAddRecord(iPhoneAddressBook, newPerson, &error);

    ABAddressBookSave(iPhoneAddressBook, &error);
    if (error != NULL)
    {
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Error" message:@"Contact not saved" delegate:nil cancelButtonTitle:@"Cancel" otherButtonTitles:nil, nil];
        [alert show];
    }else{
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Contact saved" message:@"Your contact was successfully saved" delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil, nil];
        [alert show];
    }
}

>根据苹果网站上的文档（向下滚动到页面中间的隐私），访问该地址簿必须先经过编程才能访问。这就是我最后要做的

-(void)requestPermission

        ABAddressBookRef iPhoneAddressBook = ABAddressBookCreateWithOptions(NULL, NULL);

                if (granted) {
                    // First time access has been granted, add the contact
                    [self addContactToAddressBook:iPhoneAddressBook];
                } else {
                    // User denied access
                    // Display an alert telling user the contact could not be added

        }
