Method definition for 'Randomcolor' not found

I made sure that I copied all the lines correctly, but every time i try to run Xcode I get an error in the ColorWheel implementation page stating "Method definition for 'Randomcolor' not found" on the '@implementation ColorWheel' line.

Not sure what to do here.

3 months and no answer...yikes. If you're still stuck or for anyone who has this problem in the future, I had this same problem, and after some searching online I figured out the infuriatingly simple solution: One "}" curly bracket is missing between the end of the array line of code, after "nil];" and before "return self;" on the next line of code in the ColorWheel.m file. Hope this fixes your problem!
