I am using Region Monitoring in my app and I faced a question that I couldn\'t find any answer to it. How does region monitoring work in background mode?

Answer 1

As far as I know region monitoring only works with iPhone4 and it's based on the device changing the communication towers. This way it uses way less battery than the standard background location update. Make sure you enabled the appropriate background modes. As long as you implement that delegate, you should be ready to go.
