TTMapViewDelegate

@protocol TTMapViewDelegate <NSObject>

The TTMapViewDelegate protocol defines a set of optional methods that you can use to receive map-related update messages. Because many map operations require the TTMapView class to load data asynchronously, the map view calls these methods to notify your application when specific operations complete.


                    
                    
                    -onMapReady:

Tells the delgate that the specified map view is ready to be used.

Declaration

Objective-C

Swift

optional func mapView(_ mapView: TTMapView, didPanning coordinate: CLLocationCoordinate2D)

Parameters
