How to manage Quick Blox Session?

Question

I have a question regarding Quick blox API. Right now I am sign up an user using below code.

 [QBRequest createSessionWithSuccessBlock:^(QBResponse *response, QBASession *session) {
            // session created

            QBUUser *user = [QBUUser user];
            user.password = userPasswordTextField.text;
            user.login = userNameTextField.text;
            user.fullName = userRealNameTextField.text;
            user.email = userEmailTextField.text;

            // Registration sign up of User
            [QBRequest signUp:user successBlock:^(QBResponse *response, QBUUser *user) {

                [QBRequest createSessionWithSuccessBlock:^(QBResponse *response, QBASession *session) {
                    NSLog(@"checkingl registering");
                    [QBRequest userWithLogin:user.login successBlock:^(QBResponse *response, QBUUser *user) {
                        NSLog(@"checkingl updatingqb");

                    } errorBlock:^(QBResponse *response) {
                        // Handle error
                    }];

                }errorBlock:^(QBResponse *response) {
                    // Handle error
                }];

            } errorBlock:^(QBResponse *response) {
                // Handle error here
                NSLog(@"error while signing up with QB");

                NSLog(@"fail sign Up %@",response);;

                [self showAlert:nil message:@"User with login that has already been taken" cancelButtonTitle:nil otherButtonTitle:@"OK"];


                return ;

            }];
        } errorBlock:^(QBResponse *response) {
            // handle errors
            NSLog(@" error in creating session %@", response.error);
        }];

In above code first I am creating a session and sign up an new user, then I am login user. At sign up time I did't log in user for QuickBlox Chat at signup time, But later when I will log in into Quick blox chat in another module, still I have to create new session or I have to maintain new session.

Answer 1

Any session will remain valid for 2 hours after the last request to QuickBlox. To check a session's expiration date use this next snippet of code:

NSDate *sessionExpiratioDate = [QBBaseModule sharedModule].tokenExpirationDate;
NSDate *currentDate = [NSDate date];
NSTimeInterval interval = [currentDate timeIntervalSinceDate:tokenExpirationDate];
if(interval > 0){
  // recreate session here
}

Check this guide. This feature is available since 1.8 iOS SDK.
