大家都知道skstoreproductviewcontroller的loadproductwithparamters方法需要从web请求app信息，所以加载很慢，有没有什么方法可以后台运行loadproductwithparameters来快速显示app信息呢？

The information will naturally load in the background and the intention is that you call loadProductWithParameters:completionBlock: before you actually want to display the view (and you can use the completion block to either show the view or to tag the item as being available to show).
