How to handle "Don't Allow" for location manager?

I haven't think of this yet now .

Till now whenever device was asking me use location update I was allowing it .

But when now I am not allowing then it the location manager gives me kclErrorDenied and the location manager can not start again until I restart the application .

So my question is that should I give a message to restart the app to the user or is there a solution to start working the location manager again .

thanks .

The Error :
