ios 인앱 구매 관련 충돌

Question

인앱 구매를 통해 내 앱에서 광고를 삭제하는 소모품이 없습니다. 가끔은 잘 돌아가고, 앱을 닫고 다시 열면 PRO 버전을 구입 한 경우 NSDefaults에서 탐지하는 코드가 정상적으로 작동합니다. 구입할 때 탭 바에서 "PRO로 업그레이드"버튼을 제거하려고하는데이 코드는 앱을 충돌시킵니다. 다음과 같은 오류와 함께, doRemoveAds 방법의

#import "RemoveAdsViewController.h" 
#import <StoreKit/StoreKit.h> 
#import "Flurry.h" 
#define kRemoveAdsProductIdentifier @"AiutoPro"

아이디어 여기에 - 응용 프로그램 구매 처리하는 컨트롤러입니까?

Answer 1

당신은의 dealloc 방법에

[[SKPaymentQueue defaultQueue] removeTransactionObserver:self]; 

을 넣어해야합니다. 이것은 SKIPaymentQueue에게 RemoveAdsViewController가 할당 해제 된 후에 어떤 트랜잭션도 수신하지 않음을 알립니다.
