go back to extents features and go to next extent

[LucaAlferi1]

Hi
in other Ersi'Api is possible to create the command "go back to extents features" and "go to next extent". I wanted to know if in ios there is this possibility.
Thanks

Yes, it is possible to create these commands. Here are the steps you should follow...

1. Create a retain property of NSMutableArray.
2. Listen to the "MapDidEndZooming" notification.
3. Add self.mapView.visibleArea.envelope to the array created in step 1.
4. From "Go Back" and "Go Forward" get the respective extent and zoom.
