Question

I am new to iphone development.I am creating a map application.I have toolbar below the mapview with a button on it.On clicking the button it displays as an alert to load the current location.In my button click even i hava given code to find current location

 -(IBAction) gosearch : (id) sender{
self.locationManager = [[[CLLocationManager alloc] init] autorelease];
self.locationManager.delegate = self; 
[locationManager startUpdatingLocation];
}

For me it is not displaying the alert.What should i do?Please help me out. Thanks.

You need to have your controller class implement protocol CLLocationManagerDeligate. This will mean that it gets notified of errors or when the location is posted (for example – locationManager:didUpdateToLocation:fromLocation:)

Then you can pass on the long/lat and radius of view required to the MapView
