앱 구매 중 - 때때로 앱 충돌이 발생했습니다

Question

나는 인터넷을 통해 며칠 동안보고 있으며 내 문제에 대한 해결책을 찾을 수 없습니다. 앱을 만들었고 앱 구매를 통해 광고를 삭제하길 원합니다. 내 문제는 "BuyProduct"버튼을 클릭 할 때 응용 프로그램이 충돌하는 경우입니다. 그런 다음 [[SKPaymentQueue defaultQueue] addPayment:payment]; 줄 뒤에 "스레드 1 : EXC_BAD_ACCESS (코드 = 1, 주소 = 0x16e6f6980)"오류 메시지가 나타납니다. 내 PurchasedViewController의 다음

내 .H :

​- (IBAction)PurchaseItem:(id)sender { 
_purchaseController = [[PurchasedViewController2 alloc] initWithNibName:nil bundle:nil]; 
_purchaseController.productID =@"PS.PileUp.RemoveAds"; 
[[SKPaymentQueue defaultQueue] addTransactionObserver:_purchaseController]; 
[self presentViewController:_purchaseController animated:YES completion:NULL]; 
[_purchaseController getProductID:self]; 
}

Answer 1

1 여러분과 같은 사람들은 BuyProduct 버튼을 누르는 것에서 _product를 만드는 것까지 경쟁 조건을 가지고 있습니다. 일반적으로 사용자가 BuyProduct를 누르기 전에 SKProductsRequest를 완료해야합니다. 즉, Buyproduct를 누르면 _product에 원하는 가치가 있음을 알고 있습니까?

Answer 2

Thx 나는 그것을 풀어. (ID) 보낸 사람 { NSLog : - (IBAction를) BuyProduct

- (IBAction)GoBack:(id)sender { 
[[SKPaymentQueue defaultQueue]removeTransactionObserver:self]; 
[self dismissViewControllerAnimated:YES completion:NULL];
