Getting user email during iOS InApp purchase

问题

Is there anyway in iOS to retrieve the current user email (I suppose it would be the iTunes profile email) after a InApp purchase attempt (either successful or not)?

回答1:

This is not possible with iOS public SDK (i.e. SDK 7 at this time).

cf. this question for another way to get the user's email.
