Thank you Sir. I will use in my app.

What if a user hits review and it brings it to the reviews/ratings page in the store but then the user does not leave feedback. Does this see that and keep prompting the user since they didn't truly leave a review or rating?

a1g0rithm Once user has gone pass the app and in review UI of iTunes then you don't get information if he did or didn't rated.
These dialogue are to take user to rating screen but cannot control if they rated or not
