Current location does not show

Question

I am trying to use GoogleMap API and apple's CLocationManager for my app, but it does not show my current location in either of them. I have set up the API in AppDelegate.m and also asking and checking user permission to track location. This is the code I have for map. I am trying to get user's current location and I will get user's destination and notify them when they are close to their location (using both estimated time and distance). I would appreciate if you can help me about that too. thanks

Can you check if you have defined following keys in your info.plist? All three keys are not needed, you need to define one or two of these keys depending on your uses permissions.

NSLocationAlwaysUsageDescription: Always location description
NSLocationWhenInUseUsageDescription: When in use location description
NSLocationAlwaysAndWhenInUseUsageDescription: description for both
