If you use our user authentication mode and want to be sure that new users that have just logged in will have a different chat than previous users who has logged out, just use the login and logout methods.

Check the following examples to see how you can do it in your application:

Login example

ObjC:

- (IBAction)loginPressed:(id)sender {
  HCSUser *user = [HCSUser new];

  if ([self.nameTextField.text count] > 0) {
    user.name = self.nameTextField.text;
  }
  
  if ([self.emailTextField.text count] > 0) {
    user.email = self.emailTextField.text;
  }

  user.userId = self.userId;
  
  [HelpCrunch updateUser:user completion:^(NSError * _Nullable error) {
     // We're ready to log user in
  }];
}

Swift:

@IBAction func buttonLoginPressed(_ sender: Any) {
    let user = HCSUser()
        
    user.userId = self.userId
    if nameTextField.text.count > 0 {
            user.name = nameTextField.text
    }
        
    if emailTextField.text.count > 0 {
         user.email = emailTextField.text
    }
        
    HelpCrunch.update(user) { (error) in 
        // We're ready to log user in
    }
}

Logout example:

ObjC:

- (IBAction)logout:(id)sender {
  [HelpCrunch logoutWithCompletion:^(NSError * _Nullable error) {
      // User successfully logged out
  }];
}

Swift:

@IBAction func buttonLogoutPressed(_ sender: Any) {
    HelpCrunch.logout { (error) in
        // User successfully logged out
    }
}
