if (error) {
    return;
}


NSString  *accessTocken = [auth valueForKey:@"accessToken"]; // access tocken pass in .pch file

NSLog(@"%@",accessTocken);
NSString *str=[NSString stringWithFormat:@"https://www.googleapis.com/oauth2/v1/userinfo?access_token=%@",accessTocken];
NSString *escapedUrl = [str stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"%@",escapedUrl]];
NSString *jsonData = [[NSString alloc] initWithContentsOfURL:url usedEncoding:nil error:nil];
NSDictionary *jsonDictionary = [NSJSONSerialization JSONObjectWithData:[jsonData dataUsingEncoding:NSUTF8StringEncoding] options:NSJSONReadingMutableContainers error:&error];
NSString *userId=[jsonDictionary objectForKey:@"email"];

NSLog(@" user data %@",jsonData);
NSLog(@"Received Access Token:%@",auth);
NSLog(@"email id : %@ ",userId);

GTLServicePlus* plusService = [[GTLServicePlus alloc] init];
plusService.retryEnabled = YES;
[plusService setAuthorizer:auth];
GTLQueryPlus *query = [GTLQueryPlus queryForPeopleGetWithUserId:userId];

[plusService executeQuery:query completionHandler:^(GTLServiceTicket *ticket,GTLPlusPerson *person,NSError *error) {
    if (error) {
        GTMLoggerError(@"Error: %@", error);
    } else {
        // Retrieve the display name and "about me" text
       // [person retain];
        NSString *description = [NSString stringWithFormat:
                                 @"%@\n%@", person.displayName,
                                 person.aboutMe];
        GTLPlusPersonImage *image  =person.image;
        NSString *strimag=[image valueForKey:@"url"];

        // [self setImageFromURL:[NSURL URLWithString:strimag]];
        NSData *receivedData = [NSData dataWithContentsOfURL:[NSURL URLWithString:strimag]];

        UIImage *img = [[UIImage alloc] initWithData:receivedData ];
        receivedData=UIImageJPEGRepresentation(img,50);
        NSLog(@"description %@",description);
    }
}];
 if ([GPPSignIn sharedInstance] == true) {
   [self performSegueWithIdentifier:@"pass" sender:self];
      }

  [[GPPSignIn sharedInstance] signOut];
 }

Here are some ways to save data inside application.

create local database using sqlite or coredata both provides facilty to save data locally and before use please find the different situations to use these databases.
using NSUserDefaluts but not recomemded because NSUserDefaults aren’t meant to store sensitive information for more information see imp link see example also if you still.

To store data using NSUserDefaluts:

[[NSUserDefaults standardUserDefaults]setObject:self.textfield.text forKey:@"yourKey"];

To get data anywhere inside app:

object = [[NSUserDefaults standardUserDefaults] valueForKey:@"yourKey"];

save email add from `viewController` where you entering and get from anywhere in your application using `yourKey` see my ans. — vaibhav, Sep 14 '16 at 10:49
