4. Click the Location button to trigger the method

1 //return to User location2-(ibaction) backuserlocation {3     4     //Default Zone5Mkcoordinatespan Spa = Mkcoordinatespanmake (0.01,0.02);6Mkcoordinateregion region =Mkcoordinateregionmake (self.mapView.userLocation.location.coordinate, spa);7 8 [Self.mapview setCenterCoordinate:self.mapView.userLocation.location.coordinate animated:yes];9 [Self.mapview setregion:region animated:yes];Ten}
