인엡 재구매 복구 로직(restore button)

원문(리스토어와 인엡 풀소스) - http://www.changwoo.net/bbs/bbsDetail.do?&num=545



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.




//복구 버튼 이벤트
- (void) onClickRestore:(id)sender

{

    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];

    NSArray *languages = [defaults objectForKey:@"AppleLanguages"];

    NSString *currentLanguage = [languages objectAtIndex:0];

     

    NSString *requestString = @"";

    //Language process

    if ([currentLanguage isEqualToString:@"ko"]) {

        //        requestString = @"복구 요청중";

    }else{

        //        requestString = @"Restore requesting";

    }

     

    HUD = [[MBProgressHUD alloc] initWithWindow:[[UIApplication sharedApplication] keyWindow]];

    //    HUD.center = CGPointMake(10, 110);

    [[[UIApplication sharedApplication] keyWindow] addSubview:HUD];

    HUD.delegate = self;

    HUD.labelText = requestString;

    [HUD show:YES];

- (void) checkPurchasedItems

    [[SKPaymentQueue defaultQueue] addTransactionObserver:self];

            failMessage = @"구매 기록이 없습니다.";

        }else{

            failMessage = @"There is no record of your purchase.";

        }

         

        UIAlertView *resultView = [[UIAlertView alloc] initWithTitle:@"Failed"

                                                             message:failMessage

                                                            delegate:self

        NSString *productID = transaction.payment.productIdentifier;

        [purchasedItemIDs addObject:productID];

        NSLog (@"product id is %@" , productID);

        // here put an if/then statement to write files based on previously purchased items

        // example if ([productID isequaltostring: @"youruniqueproductidentifier]){write files} else { nslog sorry}

         

        if([productID isEqualToString:KONGLISH_PRODUCTID])

  유용하게 잘 사용했습니다~
  더 요약하자면 핵심은 이거죠
  
  [[SKPaymentQueue defaultQueue] addTransactionObserver:self];
  [[SKPaymentQueue defaultQueue] restoreCompletedTransactions];//영구복원 실행
  
  - (void)paymentQueue:(SKPaymentQueue *)queue restoreCompletedTransactionsFailedWithError:(NSError *)error
  {
  if(error.code!=SKErrorPaymentCancelled)
  {
  //에러
  }
  else {
  //유저 취소시
  }
  }
  
  // Then this is called
  - (void)paymentQueueRestoreCompletedTransactionsFinished:(SKPaymentQueue *)queue
  {
  if(queue.transactions.count==0){
  //구매한 영구아이템이 없을경우
  return;
  }
  
  for (SKPaymentTransaction *transaction in queue.transactions)
  {
  //구매한 아이템들에 대한 복원 처리 
  } 
  
  }
