Can I use "backendless.userService currentUser" after exit application (iOS)

Is there any support about cache login data?
Can I use “backendless.userService currentUser” without login again?

Once you exit the application, the “backendless.userService” object is destroyed, therefore “currentUser” will not be available.

Also, we do not cache the last logged in user, however, you can do it yourself in your code.

Hope this helps.
