I was wondering how I would go about getting cocoa to call a
selector defined in a string?
You don't "call a selector," you send a message.
SEL selector = NSSelectorFromString(@"aSelector");
[object performSelector: selector withObject: nil];
In addition, if the method in question takes more than two arguments,
or takes and/or returns a non-object type, there's NSInvocation. It's
more complex, but it's capable of handling any number and type of
arguments, and any type of return value.
