애플의 정책이 바뀌어 non-consume in-app은 무조건 restore(복구) UI가 있어야 합니다, 안그러면 리젝사유가 되어 가슴아픈 경험을 하게 됩니다.

그에 따른 로직을 올립니다.

버튼에 이벤트로

- (void) onClickRestore:(id)sender 를 호출하면

checkPurchasedItems ->
 상황1 - 로그인 취소- > (void)paymentQueue:(SKPaymentQueue *)queue restoreCompletedTransactionsFailedWithError:(NSError *)error 
 상황2  - 로그인 성공 -> (void)paymentQueueRestoreCompletedTransactionsFinished:(SKPaymentQueue *)queue

요런 로직입니당
로그인이 성공하면
paymentQueueRestoreCompletedTransactionsFinished함수에서 그동안 구입한 인엡에 대한 목록(product id)을 얻어옵니다
그러면 콜백받은 인엡목록과 본어플의 인엡의 코드(product id)를 검사해서 있는지 확인한후 처리 하시면 되겠습니다.
