Hello, I am just trying to give an object a glow by using the CALayer shadowColor but i cant find out how to successfully do it. The more I look the more confusing I got. Somehow I came to CIFilter but when I try to use this it says CIFilter is undeclared (first use in this function). I believe that CIFilter is in Quartzcore.framework and i have imported in my list of frameworks as well as my implementation file. Please help. Thanks.
