ios - RMStore离线收货验证

Question

关于使用RMStore ( https://github.com/robotmedia/RMStore ) 进行离线收据验证的一个问题

在应用程序启动时，我检查该应用程序是否具有有效的应用程序内购买(专业版)(我的应用程序只有 iOS7)

我是这样做的:

RMStoreAppReceiptVerificator *verificator = [[RMStoreAppReceiptVerificator alloc] init];
BOOL isValidReceipt = [verificator verifyAppReceipt];
if (isValidReceipt)
{
    BOOL isProVersion = [[RMAppReceipt bundleReceipt] containsInAppPurchaseOfProductIdentifier:xxx];
    ...
}

我在 App Store 中还有 1.0 版本...但现在我想尽快进行更新...这在应用商店更新后仍然有效，对吗？ App 中仍会有收据，验证应该仍会通过，对吧？

我之所以问是因为测试应用内购买并不是一件容易的事(尤其是更新之类的)，如果出现问题，用户会很生气....

代码应该像以前一样工作。但是，您没有正确验证收据。引用 Receipt Validation Programming Guide :

If validation fails in iOS, use the SKReceiptRefreshRequest class to refresh the receipt.

使用 RMStore，看起来像这样:

const BOOL verified = [self verifyReceiptWithCustomLogic];
if (verified)
{
    // Verification succeeded
} 
else 
{ // Apple recommends to refresh the receipt if validation fails on iOS
    [[RMStore defaultStore] refreshReceiptOnSuccess:^{
        const BOOL verified = [self verifyReceiptWithCustomLogic];
        if (verified)
        {
            // Verification succeeded
        }
        else
        {
            // Verification failed
        }
    } failure:^(NSError *error) {
            // Verification failed
    }];
}

您的验证逻辑出现的位置:

- (BOOL)verifyReceiptWithCustomLogic
{
    RMStoreAppReceiptVerificator *verificator = [RMStoreAppReceiptVerificator new];
    if ([verificator verifyAppReceipt])
    {
        return [[RMAppReceipt bundleReceipt] containsInAppPurchaseOfProductIdentifier:xxx];
    }
    return NO;
}

请注意，刷新收据会使收据验证成为一个异步过程。
