ios - UIGestureRecogniser key-value coding -

i trying utilize key-value coding on uigesturerecogniser. line of code below crashes when tries set value. uigesturerecogniser compliant key-value coding protocol , alternatives can used?

gesture.setvalue(nsvalue(cgpoint: draggedobjectoffset), forkey: "draggedobjectoffset")

*** terminating app due uncaught exception 'nsunknownkeyexception', reason: '[ setvalue:forundefinedkey:]: class not key value coding-compliant key draggedobject.'

the issue not uigesturerecognizer doesn't adhere key value coding protocol, it's doesn't take values key "draggedobjectoffset". key value coding in many ways similar @property statements. can't assign arbitrary info arbitrary keys objects claim "key value coding-compliant".

i suggest writing simple subclass accomplish task.

ios swift uigesturerecognizer
