RMStore RequestProducts在请求产品时会提供异常

Question

我正在使用rmstore库（基于订阅），我在此行中获得异常：[[rmstore defaultStore] requestProducts：[nsset setWithArray：_products：_products Success]成功：^（nsArray *Products *Products *Products *Products *Products *Products *Products *Products *Products *Products *Products *products *products *products *products *products *products。，nsArray *无效的ProductIdentifiers）{

- (void)viewDidLoad
{
[super viewDidLoad];
_products = @[@"NEWSUB01",
              @"NEWSUB06",
              @"NEWSUB12"];
[UIApplication sharedApplication].networkActivityIndicatorVisible = YES;
[[RMStore defaultStore] requestProducts:[NSSet setWithArray:_products] success:^(NSArray *products, NSArray *invalidProductIdentifiers) {
    [UIApplication sharedApplication].networkActivityIndicatorVisible = NO;
    _productsRequestFinished = YES;

} failure:^(NSError *error) {
    [UIApplication sharedApplication].networkActivityIndicatorVisible = NO;
    UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:NSLocalizedString(@"Products Request Failed", @"")
                                                        message:error.localizedDescription
                                                       delegate:nil
                                              cancelButtonTitle:NSLocalizedString(@"OK", @"")
                                              otherButtonTitles:nil];
    [alertView show];
}];
}

以下是RequestProducts函数，例外是在线：[_ProductSrequestDelegates addobject：delegate];

- (void)requestProducts:(NSSet*)identifiers
            success:(RMSKProductsRequestSuccessBlock)successBlock
            failure:(RMSKProductsRequestFailureBlock)failureBlock
{
RMProductsRequestDelegate *delegate = [[RMProductsRequestDelegate alloc] init];
delegate.store = self;
delegate.successBlock = successBlock;
delegate.failureBlock = failureBlock;
[_productsRequestDelegates addObject:delegate];
SKProductsRequest *productsRequest = [[SKProductsRequest alloc] initWithProductIdentifiers:identifiers];
productsRequest.delegate = delegate;
[productsRequest start];
}

相同的代码在示例应用程序中起作用，但在我的应用中不起作用。

我注意到rmstore中的示例项目正在使用不可再生的IAP。对于基于自动可再生订阅的IAP，您应该将商店设置为以下：

const BOOL iOS7OrHigher = floor(NSFoundationVersionNumber) > NSFoundationVersionNumber_iOS_6_1;
_receiptVerifier = iOS7OrHigher ? [[RMStoreAppReceiptVerifier alloc] init] : [[RMStoreTransactionReceiptVerifier alloc] init];
[RMStore defaultStore].receiptVerifier = _receiptVerifier;

_persistence = [[RMStoreUserDefaultsPersistence alloc] init];
[RMStore defaultStore].transactionPersistor = _persistence;

使用rmstoreuserdefaultsististence进行事务的持久性，当您刷新或调用收据时，它将根据RMStore的文档自动持续。在链接的页面末尾检查。
