Extract email from CNContactProperty - iOS 9

I have an iOS app which needs access to the Contacts picker view controller in order to allow the user to select a contact property such as email address/ telephone numbers of imessage email addresses.

The problem I am having right now, is that I can't figure out how to parse the returned data. I have made use of the contactPicker didSelectContactProperty method, but I am unable to parse the data I need.

-(void)contactPicker:(CNContactPickerViewController *)picker didSelectContactProperty:(CNContactProperty *)contactProperty {

   CNLabeledValue *test = contactProperty.contact.emailAddresses.firstObject;
   NSLog(@"%@", test);

   NSLog(@"%@", contactProperty.contact.phoneNumbers);
}

If you run the above code you get the following response:

2015-10-11 13:30:07.059 Actions[516:212765] <CNLabeledValue: 0x13656d090: identifier=21F2B1B2-8158-466B-9224-E2036CA07D28, label=_$!<Other>!$_, value=News_Europe@iEUNS.com> 2015-10-11 13:30:07.061 App_Name[516:212765] (
    "<CNLabeledValue: 0x13672a500: identifier=6697A0E9-3B91-4566-B26E-83B87979F816, label=_$!<Main>!$_, value=<CNPhoneNumber: 0x13672a660: countryCode=gb, digits=08000391010>>" )

Thats great, but how do I extract the data I need from it? Why are the NSLog statements returning the data in a weird format?

Thanks for your time, Dan.

Solution

  • The returned values are of the CNLabeledValue class. In order to get the value from them, for, say, the emails, do this

    CNLabeledValue *emailValue = contactProperty.contact.emailAddresses.firstObject;
NSString *emailString = emailValue.value;

    If the value you wanted a phone number, this is how you would retrieve that 

    CNLabeledValue *phoneNumberValue = contactProperty.contact.phoneNumbers.firstObject;
CNPhoneNumber *phoneNumber = phoneNumberValue.value;
NSString *phoneNumberString = phoneNumber.stringValue;

    Because the returned value is a CNLabeledValue, you are also able to retrieve the phone number's or email's label

    NSString *emailLabel = emailValue.label; //This may be 'Work', 'Home', etc.
NSString *phoneNumberLabel = phoneNumberValue.label;
