Question

I've added an UIAlertView that has UIActivityIndicatior as a subview on my application. This alertView only show when the purchase is in progress. How to hide my waiting screen when In app purchase UIAlertView is show?

- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions
{
    for (SKPaymentTransaction *transaction in transactions)
    {
        switch (transaction.transactionState)
        {
            case SKPaymentTransactionStatePurchasing:
                [self stillPurchasing]; // this show a waiting screen
                break;
            case SKPaymentTransactionStatePurchased:
                NSLog(@"2");
                [self completeTransaction:transaction];
                break;
            case SKPaymentTransactionStateFailed:
                [self failedTransaction:transaction];
                break;
            case SKPaymentTransactionStateRestored:
                 NSLog(@"4");
                [self restoreTransaction:transaction];
                break;
            default:
                NSLog(@"5");
                break;
        }
    }
}

Thank you.

如果您保留它直到购买操作完全完成，这将更加有用。.这意味着在情况1（SKPaymentTransactionStatePurchased）中，您隐藏了指标，也不要忘记隐藏它，以防购买失败。
