Question

How can I call a selector with its name in NSString * in objective c? I also need to call the selector only if the target will accept it. e.g.

+(void) callMethod: (NSString *) method onObject: (id) object
{
    // do some magic
}

When I call callMethod: @"Foo" onObject: obj if obj implements Foo then [obj Foo] should be called, if it doesn’t implement it, nothing should happen.

SEL selector = NSSelectorFromString(method);
if ([object respondsToSelector:selector]) {
    [object performSelector:selector];
}
