In App Purchase關閉商店視圖後崩潰

我注意到，如果您在我的應用程序中輸入我的商店視圖（詢問蘋果產品），然後在所有產品從蘋果加載之前關閉商店視圖，它會崩潰。In App Purchase關閉商店視圖後崩潰

2012-11-05 12:32:08.420 Bellman[71368:c07] Dealloc inAppManager

正如你在我的代碼中看到的，當調用dealloc時，我打電話給removeTransactionObserver:。正如你在日誌中看到的，dealloc在應用程序崩潰前5秒被調用。從我所瞭解的默認隊列試圖呼叫productsRequest: didReceiveResponse:即使我已經刪除了我的自我觀察員？

    {

    // restarts any purchases if they were interrupted last time the app was open

當我打算「問問題」時，它只是想出了它。由於我沒有在互聯網上找到答案，我會分享我的解決方案。

由於SKProductsRequest不是SKPaymentQueue的一部分，並且SKProductsRequest實現了它們自己的委託，因此您需要刪除您在SKProductsRequest上設置的委託。

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