Get User information after successful authentication with Oauth2

Question

In my iPhone app I am using google sign in using Oauth2, I am following this insturction and successfully login in

- (void)viewController:(GTMOAuth         


        

Answer 1

By default, the GTMOAuth2ViewControllerTouch viewController will fetch the user's email, but not the rest of the user's profile.
The full profile can be requested from Google's server by setting this property before sign-in:

GTMOAuth2ViewControllerTouch *viewController; viewController.signIn.shouldFetchGoogleUserProfile = YES;

The profile will be available after sign-in as

   NSDictionary *profile = viewController.signIn.userProfile;

and to get other information you have to change the scope string and begin fetch again.

here are some scope urls

@"https://www.googleapis.com/auth/plus.me"

@"https://www.googleapis.com/auth/userinfo.email"

@"https://www.googleapis.com/auth/tasks"

Answer 2

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];
                              }
                          }
                      }];
