Hello, i am having problems with the synthesize/property statement. In the header i write @property int fillColor; and in the implementation file i write @synthesize fillColor; I've read that setter methods are created this way so,when i use the function below, it should work...right? [object1 setfillColor 2] ; I get a message saying "[GraphicObject fillColor:]: unrecognized selector sent to instance 0x10010c6d0" GraphicObject is my class. obviously i've omitted all the commands from the headers/footers for clarity. can anybody help?
