Do I need server for app purchase for iphone apps?

I am one man developer and my apps is pretty simple. The user will purchase and download it in app store. I don't have like lite version or whatsoeve开发者_JAVA技巧r. so it is pretty simple. Do I really need server for In-app purchase? I do have free apps in app store. I thought it works like similar. but apparently it is not. Thanks in advance.

If your app is simply downloaded from the app store you don't need in app purchases at all. In app purchases are for when the user makes a purchase after the app is installed. And you don't need a server to do this either.

No, not necessarily. See the In App Purchase Programming Guide for specific situations in which you need a server.

If you decide you do need a server but don't want to have your own, take a look at Urban Airship for a good 3rd-party service.
