Question

在我的应用程序中，我正在尝试实施“恢复购买”按钮，但我无法弄清楚如何获取订阅的最新购买收据。我只有一个SKProduct，一个可自动更新的订阅。

我只需要获取最新收据并将其发送到服务器进行验证。

我试过这个：

- (void)paymentQueueRestoreCompletedTransactionsFinished:(SKPaymentQueue *)queue {
        for (SKPaymentTransaction *transaction in queue.transactions) {
            if (transaction.transactionState == SKPaymentTransactionStatePurchasing) {
                NSLog(@"Purchasing");
            }
            if (transaction.transactionState == SKPaymentTransactionStatePurchased) {
                NSLog(@"Purchasing");
            }
            if (transaction.transactionState == SKPaymentTransactionStateRestored) {
                NSLog(@"Restored");
            }
            if (transaction.transactionState == SKPaymentTransactionStateFailed) {
                NSLog(@"Failed");
            }
        }
}

但我得到了这个：

2013-10-04 12:21:48.994 App[5289:60b] Purchasing
2013-10-04 12:21:48.995 App[5289:60b] Purchasing
2013-10-04 12:21:48.996 App[5289:60b] Purchasing
2013-10-04 12:21:48.996 App[5289:60b] Purchasing
2013-10-04 12:21:48.997 App[5289:60b] Purchasing
2013-10-04 12:21:48.998 App[5289:60b] Purchasing
2013-10-04 12:21:48.999 App[5289:60b] Purchasing
2013-10-04 12:21:48.999 App[5289:60b] Purchasing
2013-10-04 12:21:49.000 App[5289:60b] Purchasing
2013-10-04 12:21:49.000 App[5289:60b] Restored
2013-10-04 12:21:49.001 App[5289:60b] Restored
2013-10-04 12:21:49.001 App[5289:60b] Restored

我只需要最新的收据。我怎么能得到它？问题是由于某种原因用户购买了订阅，但无法在我的服务器上验证。为什么失败 - 我不知道。

您可以通过以下方式获取收据：

// Load the receipt from the app bundle.
NSURL *receiptURL = [[NSBundle mainBundle] appStoreReceiptURL];
NSData *receipt = [NSData dataWithContentsOfURL:receiptURL];
if (!receipt) { 
    /* No local receipt -- handle the error. */ 
}

/* ... Send the receipt data to your server ... */

这就是我所需要的。很抱歉延迟回答Nikolay Dyankov :) 有关更多详细信息，请检查here。

最好。
