You can use the objc_msgSend function. It takes two parameters, the receiver and the selector to send to it:

objc_msgSend(self, someSelector);

You'll need to turn your string into the appropriate selector using NSSelectorFromString:

NSString *message = [self getSomeSelectorName];objc_msgSend(self, message);

The method also takes a variable number of arguments, so you can send messages with any number of arguments.

NSString *message = [self getSomeSelectorNameWithManyArguments];objc_msgSend(self, message, arg1, arg2, arg3, arg4);
