I wish to create a lite version with full functionality for my application. However, this version should be available to the user from only 30 days from the day of installing the application. Even if the user deleted the application say after 20 days, and then he installs the application again, still it would mean he can use the application for 10 more days only.
As per my knowledge, if an application is un-installed, it would mean that the all the data pertaining to the application would be removed as well. How do i achieve this?
Don't know how to do that, but you might run the risk of rejection...
This is from the iPhone dev announcements...
"Don't set time limits on your "Lite" version, either for run times or life times. Applications that will only run for a set number of minutes per session, or that expire altogether after some period of time, don't recruit customers so much as leave a bad taste in their mouths. "
While they didn't flat out say "Don't do it."
They haven't flat out said a lot of stuff and then rejected apps for not complying. I think they are just a little to nice with their wording. I wish if it were a rule , they would just say... "This is a rule."
Apple generally does not allow apps like this on the app store. Lite apps have to be app in their own right, and can't suddenly stop working.
The easiest approximation is to use In App purchases to implement a subscription. Unfortunately, this generally requires tracking the subscriptions on a server. There are tutorials on this site, in addition to the info on Apple's web site if you want to read more.
