Default Point touch with zoom mapView

Hi, i'm trying catch a coordinate from touch event, i can catch but when give zoom have big numbers and when i put this in function newCoord = [mapView convertPoint:location toCoordinateFromView:mapView], get wrong coordinates, what can i do?

My code:
UITouch *touch = [touches anyObject];
CGPoint location = [touch locationInView:touch.view];
NSLog(@"locationTOUCH:%f,%f", location.x,location.y);
CLLocationCoordinate2D newCoord;
newCoord = [mapView convertPoint:location toCoordinateFromView:mapView];
NSLog(@"coordinate-%f,%f", newCoord.latitude,newCoord.longitude);

So you're trying to map touches in your view (which has your mapview) to locations onto your mapview?
Im not sure the location of touch will help you directly map to a position on the map, since its a value w.r.t the view bounds and not a geo-coordinate.
