问题
I want to use "in app purchase" for trial version of my application. But I don't have a clear idea about "in app purchase". My problem is how to implement "in app purchase" in my application and uploading process. I have already uploaded a full version of the application. Please help me.

Well, the best way to understand the InApp process is to read the Apple rules about it at http://developer.apple.com/ Everything about how to implement it in your application is described over there. See for example: https://developer.apple.com/library/ios/#documentation/NetworkingInternet/Conceptual/StoreKitGuide/Introduction/Introduction.html
