アプリにストアビューを入力して（アップルに製品を要求）、アップルからすべての製品がロードされる前にストアビューを閉じると、クラッシュすることに気付きました。

私のコードでわかるようにremoveTransactionObserver:、deallocが呼び出されたときに呼び出しています。上記のログでわかるように、アプリがクラッシュする5秒前にdeallocが呼び出されています。productsRequest: didReceiveResponse:オブザーバーとしての自分自身を削除したとしても、デフォルトのキューが呼び出そうとしていることを私は理解していますか？

私が「質問をする」を打つところだったとき、それはちょうどそれを理解しました。私はインターネットでこれに対する答えを見つけられなかったので、私は私の解決策を共有するつもりです。

はSKPaymentQueueSKProductsRequestの一部ではなく、SKProductsRequest独自のデリゲートを実装しているため、SKProductsRequestで設定したデリゲートを削除する必要があります。

-(void)dealloc {
   [[SKPaymentQueue defaultQueue] removeTransactionObserver:self];
   self.productsRequest.delegate = nil; // <----- Solution
   NSLog(@"Dealloc inAppManager");
}
