I am just double checking that you cant ask for permissions to access contacts if a user has already said no.
I know you can detect if you have access and then just prompt the user to go to settings and enable access. I just wondered if you can re-ask?
No, you cant. Actually this is controlled by the operating system. There is no need to ask twice. When a user does not want to allow access anymore he can go to settings and disable address book access for your app.
