    I did all of the steps, but I’ve encountered some errors:

    1. In ViewController.h at #import “GDataFeedContact.h” and “GDataContacts.h” it says the file can’t be found.

    2. In ViewController.m, at [self getGoogleContacts], [self contactService], and [self setContactFetchTicket:ticket] it says that the “Receiver type ViewController for instance message does not declare a method with selector ..”

    I’m using xcode 5.1.

    Hi there.. its good to see this static library. But having some issue.
    Getting Below error….
    Undefined symbols for architecture armv7:
    “_OBJC_CLASS_$_GTMOAuth2ViewControllerTouch”, referenced from:

    objc-class-ref in LoginViewController.o

    Hi! Sorry for sorta flooding your responses. I was wondering if you knew how to get other contact details such as primary address, birthdays, etc?

    Thanks! 🙂

      Hi,

      You can get the address using the following code:

      GDataStructuredPostalAddress *address = [[contact structuredPostalAddresses] objectAtIndex:0];
if (address) {
    NSLog(@"formattedAddress   :  %@", [address formattedAddress]);
}

      You can also use the following if you need the individual elements instead of the ‘formattedAddress’:

      city, countryName, countryCode, houseName, neighborhood, POBox, postCode, region, street, subregion

        Birthday:

        NSString *dob = @"";
if ([contact birthday]) {
    dob = [contact birthday];
    NSLog(@"dob   :  %@", dob);
}

        Thank you so much for all the help! One last question, is it possible to get the notes I add in my contacts? I can’t find it/get it in the gdata sources.

        // Notes
GDataEntryContent *content = [contact content];
NSString *notes = @"";
if (content && [content contentStringValue]) {
    notes = [content contentStringValue];
    NSLog(@"notes   :  %@", notes);
}

    I’m using xcode 4.2 cause my mac is only on snow leopard.

    I’m new to xcode, so this tutorial is really appreciated! Thank you for all the help! 🙂

    This is great, thanks! I was just wondering where you got the GData library (or how you created it)?
