I assume you want to do more with the selector than just invoke it---otherwise you can just use KVC and save yourself some grief. There are a few cases you may encounter here: 1. There is no setter. 2. There is a setter and the class is KVC compliant for the key. 3. There is a setter and the class isn't KVC compliant for the key, but there is a setter defined as part of a property definition. 4. (3) but without the property definition. > char* getterName = sel_getName(getterSelector); > Instead of using C strings, you can use NSStrings and NSSelectorFromString() and NSStringFromSelector()---making string manipulation much easier. However, for case (3), you'll need to do some parsing of the property attribute list from property_getAttributes(). > What would be the less costly way, performance wise, to convert the C string > "color" to "setColor"? > > I have no experience in working with strings in objc, and was hoping someone > would point me in the right direction before I start.
