ios - Is there a way to offer an In-App purchase programmatically? -


in development of version 2.0 of app, change economic model. actually, app cost 1.99$, change it's free @ first sight, features reserved users have done in-app purchase. there way offer in-app purchase users have purchased app don't have buy again full app?

to track if user has done purchase , allow him use premium features, i'll store bool in keychain. change bool yes if detect update actual new version, if user change device, solution not work , force him buy unlockable features!

thanks in advance help!

you can receipt validation. convenient way want do, don't worry if user change device.

the logic behind receipt validation should receipt , pull original application version of app. compare version number free version number.

if original application version lower free version number unlock paid content user free.
