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.
