How is information about registering Google Plus cache in iOS?

Question

I did with the username, getting the user profile using google plus.

When I exit my application without calling GoolePlus signOut with in the application

[[GPPSignIn sharedInstance]signOut];

Now the user goes to the GooglePlus application and explicitly logOut from the application or clears safari history and cookies And log in with a different GooglePlus account.

Now when I log into myApp again with GoolePlus, I get the previous account information, not the new one. Here is my code -

[GPPSignIn sharedInstance].clientID = ttGooglePlusClientID;
[GPPDeepLink setDelegate:self];

GPPSignIn *signIn = [GPPSignIn sharedInstance];
signIn.shouldFetchGooglePlusUser = YES;
signIn.shouldFetchGoogleUserEmail = YES;
signIn.clientID = ttGooglePlusClientID;
signIn.scopes = @[kGTLAuthScopePlusLogin, @"profile" ];
signIn.delegate = self;

[signIn authenticate];

To avoid this, I used this code before calling logon with GooglePlus

if ([[GPPSignIn sharedInstance]hasAuthInKeychain]) {

    [[GPPSignIn sharedInstance]signOut];
    [[GPPSignIn sharedInstance]disconnect];
}

but in this case, every time it is redirected to the GoolePlus application or safari.

How to avoid this?
