Referring to the discussion performSelector where is explained that with the following line it is possible to call a method

SEL aSelector = findTheAppropriateSelectorForTheCurrentSituation();
[anObject performSelector: aSelector];

    You’d have to look up the documentation or disassemble the binary that contains that method in order to determine exactly what it does. As for your warning, your syntax is incorrect. You should use the @selector(name) syntax in order to create a selector you can use to call [obj performSelector:].
