我有一个可自动更新的订阅。当应用程序安装在新设备上时,Apple会返回所有以前的购买收据,在这种情况下,因为它是沙盒,所以每次安装时都会收到6个收据。然后,观察者将队列发送到restoredCompleted事务。我有一种方法将交易发送到我的服务器进行Apple验证,但由于6个收据,它运行了6次。我真的只想处理最后发送的收据。
所以我正在尝试计算队列中的交易,并且只在计数达到1时验证收据。
这是我到目前为止所做的:
- (void)paymentQueue: (SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions {
if (myQueue == nil) {
myQueue = [SKPaymentQueue defaultQueue];
}
NSLog(@"Transactions in Array in My Store %@", [queue transactions]);
tCount =myQueue.transactions.count;
NSString *transCount = [NSString stringWithFormat:@"%d",tCount];
for (SKPaymentTransaction *transaction in transactions)
{ switch (transaction.transactionState)
{ case SKPaymentTransactionStatePurchased:
[self completeTransaction: transaction];
break;
case SKPaymentTransactionStateFailed:
[self failedTransaction: transaction];
break;
case SKPaymentTransactionStateRestored:
if ([transCount isEqualToString:@"1"]) {
[self restoreTransaction: transaction];
}
else {
tCount--;
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^(void) {
[[SKPaymentQueue defaultQueue] finishTransaction: transaction];
});
}
default:
break;
}
}
return;
}
恢复循环,但计数不会减少。这可能是简单而愚蠢的事情。有人能告诉我如何减少这个数量吗?
谢谢!
答案 0 :(得分:2)
我等到restoreCompletedTransactionsFinished,然后将收据发送到我的服务器以验证Apple。这样就无法发送每张收据,这些收据在几个月后就会变得繁重。所以,不需要减少交易cout。
