在iOS模拟器中购买是众所周知的“不,这是不可能的”.但是,通过向在iOS 11之前工作的SKProductsRequest提供产品标识符来检索SKProduct信息.
在SKProductsRequestDelegate中我收到以下错误：Error Domain = SSErrorDomain Code = 0“无法连接到iTunes Store”
根据我的发现,当产品标识符错误或Apple SandBox服务器关闭时,可能会发生这种情况.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 guides中的实现非常相似
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.
解决方法
同样在这里.如果您在失败时重复请求,请再试一次.在无数次重复之后,它将最终返回产品.重复可能需要10次,50次甚至超过100次.
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];
}
}
