Google Plus - Getting Error While Fetching Friends Details - ios

Question

Hi i'm successfully loged in google plus. Now i'm trying to fetch friends details like emails, image, name.But getting error.
Please any one could help me, where i'm making mistake -
I tried this code -
- (void)finishedWithAuth: (GTMOAuth2Authentication *)auth
error: (NSError *) error {
self.plusService.authorizer = auth;
NSLog(#"%#",[NSString stringWithFormat:#"Email---> %#\n\n",[GPPSignIn sharedInstance].authentication.userEmail]);
NSLog(#"Received error %# and auth object ---> %#\n\n",error, auth);
// 1. Create a |GTLServicePlus| instance to send a request to Google+.
GTLServicePlus* plusService = [[GTLServicePlus alloc] init] ;
plusService.retryEnabled = YES;
// 2. Set a valid |GTMOAuth2Authentication| object as the authori zer.
[plusService setAuthorizer:[GPPSignIn sharedInstance].authentication];
// 3. Use the "v1" version of the Google+ API.*
plusService.apiVersion = #"v1";
GTLQueryPlus *query = [GTLQueryPlus queryForPeopleListWithUserId:#"me" collection:kGTLPlusCollectionVisible];
[plusService executeQuery:query
completionHandler:^(GTLServiceTicket *ticket,
GTLPlusPeopleFeed *person,
NSError *error) {
if (error)
{
GTMLoggerError(#"Error: %#", error);
}
else {
NSArray *peopleList = person.items;
NSLog(#"--People_List--->%#",peopleList);
}}];
}
Getting Error -

for Fetching Friends Details you can use Google Contacts api
in that use
#import "GDataFeedContact.h"
#import "GDataContacts.h"
class file
then use this code to get data
-(void)getGoogleContacts
{
GDataServiceGoogleContact *service = [self contactService];
GDataServiceTicket *ticket;
BOOL shouldShowDeleted = TRUE;
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];
}
//pass the useremail and password.here
NSString *username = #"youremai#gmail";
NSString *password = #"yourpassword";
[service setUserCredentialsWithUsername:username
password:password];
return service;
}
- (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]);
[googleContacts removeAllObjects];
for (int i = 0; i < [contacts count]; i++) {
GDataEntryContact *contact = [contacts objectAtIndex:i];
// Name
NSString *ContactName = [[[contact name] fullName] contentStringValue];
NSLog(#"Name : %#", ContactName);
// Email
GDataEmail *email = [[contact emailAddresses] objectAtIndex:0];
NSString *ContactEmail = #"";
if (email && [email address]) {
ContactEmail = [email address];
NSLog(#"EmailID : %#", ContactEmail);
}
// Phone
GDataPhoneNumber *phone = [[contact phoneNumbers] objectAtIndex:0];
NSString *ContactPhone = #"";
if (phone && [phone contentStringValue]) {
ContactPhone = [phone contentStringValue];
NSLog(#"Phone : %#", ContactPhone);
}
// Address
GDataStructuredPostalAddress *postalAddress = [[contact structuredPostalAddresses] objectAtIndex:0];
NSString *address = #"";
if (postalAddress) {
NSLog(#"formattedAddress : %#", [postalAddress formattedAddress]);
address = [postalAddress formattedAddress];
}
// Birthday
NSString *dob = #"";
if ([contact birthday]) {
dob = [contact birthday];
NSLog(#"dob : %#", dob);
}
if (!ContactName || !(ContactEmail || ContactPhone) ) {
NSLog(#"Empty Contact Fields. Not Adding.");
}
else
{
if (!ContactEmail ) {
ContactEmail = #"";
}
if (!ContactPhone ) {
ContactPhone = #"";
}
NSArray *keys = [[NSArray alloc] initWithObjects:#"name", #"emailId", #"phoneNumber", #"address", #"dob", nil];
NSArray *objs = [[NSArray alloc] initWithObjects:ContactName, ContactEmail, ContactPhone, address, dob, nil];
NSDictionary *dict = [[NSDictionary alloc] initWithObjects:objs forKeys:keys];
[googleContacts addObject:dict];
}
}
NSSortDescriptor *descriptor =
[[NSSortDescriptor alloc] initWithKey:#"name" ascending:YES selector:#selector(localizedCaseInsensitiveCompare:)];
[googleContacts sortUsingDescriptors:[NSArray arrayWithObjects:descriptor, nil]];
