ios - 付款队列 :(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions is not called while restoreCompletedTransactions

Question

您好，我需要在 Inapp-Purchase 中实现恢复功能，为此制作了一个调用方法的“恢复”按钮

-(void)restorePurchasedProductsWithProductId:(NSString*)prodID
{
    _productIdsArray = [[NSMutableArray alloc] init];
    productID = [prodID retain];
    [[SKPaymentQueue defaultQueue] restoreCompletedTransactions];
}

它给了我一个弹出窗口，让我输入 apple id 的密码。然后什么都没有发生。

我在某处读到它叫

- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions

所以我喜欢这个

- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions
{
    NSLog(@"paymentQueue");
    for (SKPaymentTransaction *transaction in transactions)
    {
        switch (transaction.transactionState)
        {
            case SKPaymentTransactionStatePurchased:
                [self completeTransaction:transaction];
                break;
            case SKPaymentTransactionStateFailed:
                [self failedTransaction:transaction];
                break;
            case SKPaymentTransactionStateRestored:
                NSLog(@"restored");
                [self restoreTransaction:transaction];
                break;
            default:
                break;

        }
    }
}

但问题是上面的方法既没有调用this

- (void)paymentQueueRestoreCompletedTransactionsFinished:(SKPaymentQueue *)queue

也不是

-(void)paymentQueue:(SKPaymentQueue *)queue restoreCompletedTransactionsFailedWithError:(NSError *)error

我还包含了所需的协议(protocol)，

有人能帮我解释为什么这些委托(delegate)方法不调用恢复过程吗？我正在尝试使用测试帐户。

您需要确保实现 paymentQueueRestoreCompletedTransactionsFinished: 和 paymentQueue: restoreCompletedTransactionsFailedWithError: 的类已注册为您的支付队列的观察者。

如果您在 UIViewController 中编写了这段代码，请尝试将其添加到您的 viewDidLoad 中:

[[SKPaymentQueue defaultQueue] addTransactionObserver:self];

在 viewDidDisappear 中:

[[SKPaymentQueue defaultQueue] removeTransactionObserver:self];
