多值网址地址簿iphone

我想在地址簿中创建一个新联系人.
当您想要存储更多URL(Web地址到某些社交网络)时,会出现此问题.
我的代码在iOS6的模拟器中完美运行.但在使用iOS6的真实iPhone中,存储除网址之外的所有值.
我一直在找几天找不到解决办法,如果有人能提供帮助,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,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",(__bridge CFStringRef)_linkedinField.text,(CFStringRef)@"Linkedin",(__bridge CFStringRef)_googleField.text,(CFStringRef)@"Google+",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];
    }
}

谢谢！
