iphone application payment from website,Apple's payment policy

I am developing a game application with majority of web content,but also have to provide support for iPhone. Here users have to first register on the server from the website,and based on their payment they are given membership type (gold,silver,etc) for the game. They can play the game on i开发者_C百科Phone also,using registration ids to indicate user type.Each time on gameplay certain amount is deducted from their account. The iPhone version of game also keeps tab on amount remaining and prompts user to replenish on server. Payment is entirely on server side and only data is passed through iphone application.

Does this in anyways violates Apples rules?? Can it cause App rejection??

I don't know 100% but it sounds like it might if not invalidate sail pretty close to what Apple sees as acceptable. Why don't you deal with all payments through a web-based site and simply allow registered users to access the game via iPhone. When a user runs out of time you could simply suspend the app and start up a web browser to access your site / renew game time.

Also (and I am not familiar with this) but in app purchases might be a good way to go?

all the best
