iphone - iOS Verify previous app purchase/install -


is there way verify apple servers when user first installed app? let's have payed app , want make free ads not send ads bought.

since it's not iap assume store kit out of question.

later edit: problem being ones buy, delete , reinstall.

nope, can't that! best way remove current app app store , relaunch using different bundle id. people bought can keep how is, although won't updates.

a possible workaround

here's workaround thought of. when send out next update, set flag in nsuserdefaults mark has paid user. next update only; remove code right after update. then, when send out version ads, check flag determine if should display them. problem if paid user ever re-installed app, see ads on.
