if I long press the image, the lldb debug says "Cancelling drag operation because no item was put on pasteboard", and further lock to the method "- (SPDragSource*)sourceUnderLocation:(CGPoint)locationInWindow" in DragonController.m when calling "source = objc_getAssociatedObject(view, kDragSourceKey);" which always return nil to source.

and I did notice that view and kDragSourceKey have value.

your suggestion is appreciated

Hey @samye1976, sorry it took so long. Yeah, the "enable interaction" thingie is tricky, I run into that one often! I should make a note in the readme or something.
