How can I retrieve the app purchase date in order to expire features after a set period of time?

Question

Is there an easy way to recover the app purchase date? Or must I save it myself the first time an app is opened?

Answer 1

You'll need to save it yourself the first time the app opens.

The date in the iTunesMetaData.plist changes whenever the user downloads an update and I don't think Apple would let you access file this anyway.
