Solved it using this code

 NSURL *url = [NSURL URLWithString:@"https://www.googleapis.com/plus/v1/people/me/activities/public"];
            NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
            [self.auth authorizeRequest:request
                      completionHandler:^(NSError *error) {
                          NSString *output = nil;
                          if (error) {
                              output = [error description];
                          } else {
                              // Synchronous fetches like this are a really bad idea in Cocoa applications
                              //
                              // For a very easy async alternative, we could use GTMHTTPFetcher
                              NSURLResponse *response = nil;
                              NSData *data = [NSURLConnection sendSynchronousRequest:request
                                                                   returningResponse:&response
                                                                               error:&error];
                              if (data) {
                                  // API fetch succeeded
                                  output = [[NSString alloc] initWithData:data
                                                                 encoding:NSUTF8StringEncoding] ;

                                  NSError* error;
                                  NSDictionary* json = [NSJSONSerialization
                                                        JSONObjectWithData:data

                                                        options:kNilOptions
                                                        error:&error];



                                  NSArray *array=[json objectForKey:@"items"];
                                  if (array.count>0) {
                                      NSDictionary *dicts=[array objectAtIndex:0];

                                      //  NSLog(@"actor:%@",[dicts objectForKey:@"actor"]);
                                      //[self updateUI:[dicts objectForKey:@"actor"]];
                                      // [dictUserInfo setObject:[[[dicts objectForKey:@"actor"] objectForKey:@"image"]objectForKey:@"url"] forKey:@"imageUrl"];


                                      if([delegate respondsToSelector:@selector(userPicChanged:)])
                                      {
                                          //send the delegate function with the amount entered by the user
                                          [delegate userPicChanged:[[[dicts objectForKey:@"actor"] objectForKey:@"image"]objectForKey:@"url"]];
                                      }



                                  }


                              } else {
                                  // fetch failed
                                  output = [error description];
                              }
                          }
                      }];
