Maintaining in-app-purchases in iOS -

i implementing ios app in want add together in-app purchase (iap).

i want utilize in-app purchase below situation:

1) user create registration , pay $10.

2) now, app allow user download songs. (for ex. 10 songs of $1. user can download 10 songs.)

3) user can add together more credit 1 time again making purchase of $10. (so if user wants pay 2 times he/she $20 in his/her account. , can download 20 songs of $1.)

4) while downloading song, app check whether user has plenty balance or not, can download data. (if there no balance inquire create payment of $10 first.)

i have create research above situation , looked in-app purchase guidelines apple.

from that, come across below: 1) if utilize subscription: in case, user charged after duration (for ex. monthly payment, 3 month payment). don't want. because want user pay if wants download info , not have balance. think, subscription not ideal.

2) if user consumable in-app purchase: here, can utilize it, user can pay many times want. , need track balance server side. so, server apis, can check user's balance. think, may conflict apple rules.

"consumable items 1 exception requirement content available on user’s devices. consumable items digital items used or disappear after utilize , can never reused. examples of consumable items include virtual poker chips, in-game ammunition, or virtual supplies such construction materials."

so, user can create payment iphone device. , can download songs ipad device well. means, purchase sharable. but,

consumables device-by-device items, purchase needs made understanding tied specific device. apple not allow restore purchased consumable. should warn users consumables not shareable, , create easy users purchase smaller blocks of items.

so can helps kind of in-app purchase suitable above , according apple rules regarding in-app purchase.

thanks in advance.

user "non-renewing subscription" should fit requirement https://developer.apple.com/library/ios/documentation/languagesutilities/conceptual/itunesconnectinapppurchase_guide/chapters/creatinginapppurchaseproducts.htm
