osx - Custom NSControl classes in OS X 10.10 -

-

i need develop new custom nscontrol. of guides , examples can find (including apple's subclassing nscontrol article) built around nscell. of 10.10, of cell-related messages on nscontrol have been deprecated.

i tried creating subclass , adding project via custom view in ib, can't control accept first responder despite being enabled, setting refusesfirstresponder no, , return yes acceptsfirstresponder. , i'm sure i'm missing lot of functionality (value change notifications, etc.) supposed there.

is there newer reference around shows how controls supposed developed? google-fu letting me down if there is. thanks!
