Need to offer integrate gmail account in iOS development

I recently used the gmail api to get gmail contacts and their email in my table view. Gmail api is deprived, so you may not have the proper documentation for this.

To implement gmail, use the libGDataTouchStaticLib.a library with Gdata headers (google search to send email in another case, I will send you my zip code).

The code for receiving gmail data is as follows

- (void)getGoogleContacts {

    GDataServiceGoogleContact *service = [self contactService];
    GDataServiceTicket *ticket;

    BOOL shouldShowDeleted = TRUE;

    // request a whole buncha contacts; our service object is set to
    // follow next links as well in case there are more than 2000
    const int kBuncha = 2000;

    NSURL *feedURL = [GDataServiceGoogleContact contactFeedURLForUserID:kGDataServiceDefaultUser];

    GDataQueryContact *query = [GDataQueryContact contactQueryWithFeedURL:feedURL];
    [query setShouldShowDeleted:shouldShowDeleted];
    [query setMaxResults:kBuncha];

    ticket = [service fetchFeedWithQuery:query
                                delegate:self
                       didFinishSelector:@selector(contactsFetchTicket:finishedWithFeed:error:)];

    [self setContactFetchTicket:ticket];
}

- (void)setContactFetchTicket:(GDataServiceTicket *)ticket {

    mContactFetchTicket = ticket;
}

- (GDataServiceGoogleContact *)contactService {

    static GDataServiceGoogleContact* service = nil;

    if (!service) {

        service = [[GDataServiceGoogleContact alloc] init];

        [service setShouldCacheResponseData:YES];
        [service setServiceShouldFollowNextLinks:YES];
    }

    // update the username/password each time the service is requested
    NSString *username = [txtUserName text];
    NSString *password = [txtPasswrod text];

    [service setUserCredentialsWithUsername:username
                                   password:password];

    return service;
}


// contacts fetched callback
- (void)contactsFetchTicket:(GDataServiceTicket *)ticket
           finishedWithFeed:(GDataFeedContact *)feed
                      error:(NSError *)error {

    if (error) {

        NSDictionary *userInfo = [error userInfo];
        NSLog(@"Contacts Fetch error :%@", [userInfo objectForKey:@"Error"]);
        if ([[userInfo objectForKey:@"Error"] isEqual:@"BadAuthentication"]) {

            UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Error!"
                                                                message:@"Authentication Failed"
                                                               delegate:self
                                                      cancelButtonTitle:@"Ok"
                                                      otherButtonTitles:nil, nil];
            [alertView show];

        } else {

            UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Error!"
                                                                message:@"Failed to get Contacts."
                                                               delegate:self
                                                      cancelButtonTitle:@"Ok"
                                                      otherButtonTitles:nil, nil];
            [alertView show];
        }

    } else {

        NSArray *contacts = [feed entries];
        NSLog(@"Contacts Count: %d ", [contacts count]);
        [mutAryGoogleContacts removeAllObjects];
        for (int i = 0; i < [contacts count]; i++) {

            NSMutableDictionary *aDictContactDetails=[NSMutableDictionary dictionary];


            GDataEntryContact *contact = [contacts objectAtIndex:i];
            // Email
            GDataEmail *email = [[contact emailAddresses] objectAtIndex:0];
            NSString* ContactEmail = [email address];
            if (ContactEmail) {
                [aDictContactDetails setObject:ContactEmail forKey:@"email"];




            // Name
            NSString *ContactName = [[[contact name] fullName] contentStringValue];
            if (ContactName) {
                [aDictContactDetails setObject:ContactName forKey:@"friendName"];

            }
            [mutAryGoogleContacts addObject:aDictContactDetails];

            }

        }

       //Push to next vc or do whatever you want
    }
