A way to disable Vertex Add on Vertex Editing in iOS SDK

Question

In attempting to prevent unintentional vertex additions when a user is trying to pan the map during a polygon geometry edit, is there any way to disable this default behavior of vertex adds on all touch events when a polygon edit session is active (allowVertexEditing) within the iOS SDK?  We want to allow them to move vertices within the polygon but there is no need to add new vertices outside of the ones generated on existing vertex moves.

Nevermind - I realize that you still want to be able to move vertices. I don't think we have anything at this time that allows you to move but not add vertices.

There is an `editConfiguration` property of the sketch editor. On that property you can set the `vertexEditMode` to `AGSSketchVertexEditModeSelectOnly` (`.selectOnly` if using Swift). I think that should do what you want:

/**

Specifies permitted operations on the vertices of the geometry.

@since 100.2

*/

typedef NS_ENUM(NSInteger, AGSSketchVertexEditMode) {

AGSSketchVertexEditModeInteractionEdit, /*!< Users can interactively select, add, remove, and move vertices. */

AGSSketchVertexEditModeSelectOnly       /*!< Users can interactively only select vertices. Vertices cannot be added, moved, or removed interactively. */

};

Eric,

Thank you for the clarification.  After a quick look, I don't see anything that will immediately solve your problem, but let me dig into it a bit more and get back to you.

Cheers,
