SKProductsRequest无法在iOS 11模拟器中运行

Question

在iOS模拟器中购买是众所周知的"不,这是不可能的".但是,SKProduct通过向SKProductsRequestiOS 11之前的工作提供产品标识来检索信息.

在SKProductsRequestDelegate我收到以下错误:Error Domain=SSErrorDomain Code=0 "Cannot connect to iTunes Store" 从我发现,这可能发生在产品标识符错误或Apple Sandbox服务器关闭时.然而事实并非如此,因为产品在iOS 10上运行良好.

我对产品提取的实现与Apple指南中的实现几乎相同

是否有其他人遇到此问题或找到解决方案？

当应用程序在物理设备上运行时,产品正在正常加载.我正在使用Xcode 9.0.

同样在这里。如果您在请求失败时重复请求，请再试一次。经过无数次的重复后，它最终会返回产品。可能需要 10、50 甚至 100 多次重复。

所以这就是我的代码现在的样子：

- (void)inquireProducts {
    _availableProducts = [NSMutableArray arrayWithCapacity:0];
    NSURL *url = [[NSBundle mainBundle] URLForResource:@"productIds" withExtension:@"plist"];
    knownProductIdentifiers = [NSArray arrayWithContentsOfURL:url];
    if (knownProductIdentifiers && knownProductIdentifiers.count) {
        // Keep a strong reference to the product request
        productsRequest = [[SKProductsRequest alloc]initWithProductIdentifiers:[NSSet setWithArray:knownProductIdentifiers]];
        productsRequest.delegate = self;
        [productsRequest start];
    }
}

#pragma mark SKProductsRequestDelegate method

- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response {
    for (SKProduct *product in response.products) {
        [_availableProducts addObject:product];
    }
    productsRequest = nil;
    [[NSNotificationCenter defaultCenter] postNotificationName:IAPPurchaseNotification object:self];
}

- (void)request:(SKRequest *)request didFailWithError:(NSError *)error {
    if (request == productsRequest) {
        static int count = 0;
        NSLog(@"Request %@ failed on %d. attempt with error: %@", request, ++count, error);
        productsRequest = nil;
        // try again until we succeed
        [self inquireProducts];
    }
}
