RMStore requestProducts在请求产品时提供exception

我正在使用RMStore库进行IAP（基于订阅），我在此行获得exception：[[RMStore defaultStore] requestProducts：[NSSet setWithArray：_products] success：^（NSArray * products，NSArray * invalidProductIdentifiers）{

- (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]; }]; } 

下面是requestProducts函数，exception在行：[_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]; } 

相同的代码适用于示例应用，但在我的应用中无效。

有一点我注意到RMStore中的示例项目使用的是不可更新的IAP。 对于基于IAP的自动续订订阅，您应该将商店设置如下：

 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RMStoreUserDefaultsPersistence进行事务的持久性，并且当您刷新或调用收据时，它将根据RMStore的文档自动保留 。 请在页面末尾的链接处查看。
