I am encountering this error when I am loading an Ad Hoc build of my Push Notification enabled iPhone app onto my device:
no valid aps-environment entitlement found for application
What does it mean, and how do I repair it?
I found the solution. In my project info under Build > Code Signing Identity I had it set to automatic, and it was selecting an AdHoc distribution profile which did not have push notifications enabled. (It was the wrong one.) I have selected the correct profile and the error is gone.
