This method displays two prompts: an initial prompt, and a second prompt that appears only after an event occurs that requires Always authorization. The initial prompt uses the purpose string from the

Your app can receive permanent Always authorization if the user chooses to grant permission when the second prompt appears during the Provisional Always state. Your app will receive the following calls to your delegate’s
If the user chooses Always authorization, the system doesn’t call your delegate because it already has (provisional) Always authorization. Core Location removes the provisional status, making the Always authorization permanent and your app receives the location event.
If the user chooses When In Use authorization, the system calls your delegate with When In Use authorization. Your app does not receive the location event.
Your app can no longer ask for Always authorization after the user responds to this prompt. Calling this method again will have no effect.
