IKImageView offers an 'imageCorrection' property, which takes a CIFilter and, presumably, uses it when displaying the image.
When I tried using it recently, it didn't work for me. When I set the property to a new CIFilter instance, it remains nil.
Has anyone managed to use this successfully?
You probably didn't hook up your outlet to your image view, so the pointer in your outlet is
nil
, so you sent yoursetImageCorrection:
message (whether implicit or explicit) tonil
.
