I got this error while building an iPhone application that is going to use APNS. I am still trying to figure out what is causing this problem. A more detailed error message is here:-
"Error Domain=NSCocoaErrorDomain Code=3000 UserInfo=0x113e80 "no valid 'aps-environment' entitlement string found for application" APNS Error
APNS Error
Apple’s has announced a push notification service for the iPhone that it’ll provide to all developers. It’ll maintain a persistent IP connection to the phone and let a 3rd party server ping Apple’s notification service in order to push out notifications to users device, which can be in the form of badges, sounds or custom textual alerts. According to Apple, the service will preserve battery life and maintain performance, not to mention work over WiFi or cellular.
