Version 1.1 of Cocoa Touch Diagram control contains the following new features and improvements -

Flip shapes
The shape of a ShapeNode can be flipped horizontally or vertically. Enable the allowFlip property and the shape flips when an edge is dragged over its opposite edge. You can get or set current flip state using flipX and flipY properties.



Spline link shape
The new spline element of LinkShape enumeration draws links as interpolating splines that pass through all of their control points:


Miscellaneous
~ Behavior.PanAndModify lets you select and modify when touch gesture starts over an item, or pan the view otherwise;
~ nodeCreated event is now also raised after creating nodes via drag-and-drop from NodeListView;
