I written the following code in ViewController.m

[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
GPPSignIn *signIn = [GPPSignIn sharedInstance];
signIn.shouldFetchGooglePlusUser = YES;
//signIn.shouldFetchGoogleUserEmail = YES; // Uncomment to get the user's email
// You previously set kClientId in the "Initialize the Google+ client" step
signIn.clientID = kClientId;
// Uncomment one of these two statements for the scope you chose in the previous step
signIn.scopes = @[ kGTLAuthScopePlusLogin]; // "https://www.googleapis.com/auth/plus.login" scope
signIn.scopes = @[ @"profile" ]; // "profile" scope
// Optional: declare signIn.actions, see "app activities"
signIn.delegate = self;
[signIn trySilentAuthentication];
}

self.signInButton.hidden = YES;

[self getPeopleInfo];
} else {
