Subscriptions are handled just like any other product purchase, there is no difference in the code. You can certainly add a Codeless IAP Button for a subscription.

Also, be sure to be monitoring the device logs which is quite critical to successful IAP development. You might want to check out the Sample IAP Project here Sample IAP Project .
