I am trying to fetch location by using map kit in IOS but (location manager)these function is not getting called

Answer 1

You never init the CLLocationManager object anywhere. Put the following code in the View Did Appear
obLocatinManager = CLLocationManager()
When you use simulator you can invoke location change by this menu. I gotta need to make some change first I think to try to catch the location change delegate in the simulators.

Answer 2

put obLocatinManager = CLLocationManager() in view did Appear and run it on to real device.
