Question

I need to pass a method name to @selector(method) inside a loop where the method is a value contained in an array.

[myButton addTarget:self action:@selector(method:)  forControlEvents:UIControlEventTouchDown];

How can I define a @selector() inside a loop an avoid having to hard code each @selector(method)? Can I pass in a string value?

You can use either NSSelectorFromString(), which maps an NSString to a SEL, or you can use sel_registerName(), which maps a char* to a SEL.
