应用内购买自动续费交易恢复问题

发布于 2024-12-04 04:39:05 字数 1196 浏览 1 评论 0原文

我正在开发一个应用程序，用户可以在其中购买自动续订订阅。购买部分工作正常，但当用户删除应用程序并尝试恢复其购买时会出现问题。以下是我为处理该问题而编写的代码。

我已经给出了一个标题为“已经是订阅者”的按钮。当用户点击时，我调用以下代码。

[[SKPaymentQueue defaultQueue] addTransactionObserver:self];
[[SKPaymentQueuedefaultQueue]restoreCompletedTransactions];

这就是我在 - (void) paymentQueue:(SKPaymentQueue *)queue UpdatedTransactions:(NSArray *)transactions 方法中处理恢复的方式。

 案例 SKPaymentTransactionStateRestored：
        持续时间 = [strDuration intValue];
        if(transaction.transactionReceipt != nil){
            收据 = [[NSString alloc] initWithData:[b64 dataByBase64EncodeFromData:transaction.transactionReceipt] 编码:NSASCIIStringEncoding];
            [userDefault setObject:transaction.transactionReceipt forKey:@"LastReceipt"];
            [队列完成事务：事务]；
            [自调用ReceiptInfoImpl];
        }
        休息;

以下是恢复事务完成时的委托方法。
-(void) paymentQueueRestoreCompletedTransactionsFinished:(SKPaymentQueue *)队列{ NSLog(@"已完成的事务已恢复"); }

是，当用户单击“已经是订阅者”按钮时，步骤 1. 会被调用，但步骤 2. 永远不会被调用。最后我可以在屏幕上看到消息“已完成交易已恢复”。

如果有人遇到类似的问题，请指导。

感谢您的阅读......

I am developing an application in which user can purchase auto-renewable subscription. Buying part is woking alright but problem occurs when user deletes the application and tries to restore his purchases. following is the code I wrote to handle that.

I have given a button titled "Already a Subscriber". When user tap that I call following code.

[[SKPaymentQueue defaultQueue] addTransactionObserver:self];
[[SKPaymentQueue defaultQueue] restoreCompletedTransactions];

And this is how I handle restore in - (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions method.

        case SKPaymentTransactionStateRestored:
        duration = [strDuration intValue];
        if(transaction.transactionReceipt != nil){
            receipt = [[NSString alloc] initWithData:[b64 dataByBase64EncodeFromData:transaction.transactionReceipt] encoding:NSASCIIStringEncoding];
            [userDefault setObject:transaction.transactionReceipt forKey:@"LastReceipt"];
            [queue finishTransaction:transaction];
            [self callReceiptInfoImpl];
        }
        break;

Following is delegate method when restore transaction is completed.
-(void)paymentQueueRestoreCompletedTransactionsFinished:(SKPaymentQueue *)queue{ NSLog(@"COMPLETED TRANSACTION RESTORED"); }

Problem is that, when user clicks button "Already a subscriber" then Step 1. gets called but Step 2. never gets called. Finally I can see message "COMPLETED TRANSACTION RESTORED" on screen.

If anybody has faced similar problem then please guide.

Thanks for reading.....

在你的类中，你必须实现回调
函数 paymentQueue:updatedTransactions:
此功能将在何时接收交易更新
它被制作了。因为即使应用程序处于运行状态，您的交易也会发生
已关闭，您应该准备好尽快接收这些通知
你打开应用程序。所以最好的地方是初始化它
applicationDidFinishLaunching 或等效方法。
