问题 I have my local notification working, but when I click View to come back to the app, in the app delegate I am trying to load a specific view, but it wont take. Is this possible or not?

问题 I would like to use the iBeacon Feature in an iPad App to act as a beacon transmitter and an iphone App to receive the beacons. I was able to build both apps accordingly but now I ran into some strange problems: iBeacon Transmitter the iPad app acts as the transmitter of the beacon signal.
