我根据应用程序内购买编程指南使用以下代码来请求产品列表.它曾经在我的iPhone应用程序中正常工作,但现在每次请求产品列表时它都会崩溃.(void)productsRequest:(SKProductsRequest **)request didReceiveResponse:(SKProductsResponse **)response永远不会调用委托方法.
SKProductsRequest *request = [[SKProductsRequest alloc] initWithProductIdentifiers:[NSSet setWithObject:@"my.product.identifier"]];
[request setDelegate:self];
[request start];
正如我所说,它工作得非常好,然后停止工作.这是在调用上面的代码时发生的崩溃.
