I am selling apps via In-App within my App, currently what I am doing is, when anyone has already purchased the In-App item, then at the time of update it ask for purchase it again, it doesn't charge any money but it asks each time for log in and password, Is any way to skip this log in progress, I want it should be updated without asking for purchase and log in password.

您必须以某种方式在磁盘上缓存用户的购买历史记录以防止这种情况发生，否则您必须要求用户至少向 Apple 进行一次身份验证（通过运行交易恢复或重新购买您的产品）。
