应用内购买错误的恢复按钮

问题描述

我在我的应用中恢复应用内购买时出现问题

I got a problem while restoring an in-app purchase in my app

我已经在我的项目中应用了这行代码：

I already applied this lines of codes in my project:

[[SKPaymentQueue defaultQueue] addTransactionObserver:self];

[[SKPaymentQueue defaultQueue] restoreCompletedTransactions];

但它调用此函数

- (void)paymentQueue:(SKPaymentQueue*)queue restoreCompletedTransactionsFailedWithError:(NSError*)error
{
    NSLog(@"error");
}

我必须做些什么才能避免出现此错误？并调用此函数：

What must I need to do to avoid getting this error? and call this function:

- (void) paymentQueueRestoreCompletedTransactionsFinished:(SKPaymentQueue *)queue
{
    NSMutableArray *purchasedItemIDs = [[NSMutableArray alloc] init];

 NSLog(@"received restored transactions: %i", queue.transactions.count);
    for (SKPaymentTransaction *transaction in queue.transactions)
    {
        NSString *productID = transaction.payment.productIdentifier;
        [purchasedItemIDs addObject:productID];
    }

}

先谢谢你们！

推荐答案

我在模拟器测试时遇到了同样的问题。在物理设备上试用它，因为模拟器上没有应用内购买。

I had the same problem while testing from the simulator. Try it on a physical device since in-app purchases are not available on simulator.
