ios SKStoreProductViewController loadProductWithParameters:completionBlock error process

Question

i use the SKStoreProductViewController,when pass the right id to the method loadProductWithParameters:completionBlock:,it all goes very well ,but when pass a wrong id to this method,it doesn't callback the completionBlock with error message.

Answer 1

We saw this as well. By trial-and-error we deduced that presenting the store kit view controller after the call to loadProductWithParameters:completionBlock: made the completion block run.
