iphone - how to add custom view to interface builder in iOS -

-

this question has answer here:

i using framework includes header .h files. there view called pfimageview have added story boards. did first dragging uiimageview custom prototype cell. changed uiimageview class pfimageview. dragged view class create iboutlet.

when run app, error:

unknown class pfimageview in interface builder file. [uiimageview setfile:]: unrecognized selector sent instance 0x97a9150

the framework added project target. .m file not viewable/available in framework. there else need have interface builder recognize file?

maybe it's subclass of uiview, not uiimageview?

or, why not alloc init pfimageview , addsubview?
