NSExpression defines this method:

+ (NSExpression *)expressionForFunction:(NSString *)name arguments: (NSArray *)parameters

and the doco provides this example:

[NSExpression expressionForFunction:(@selector(random)) arguments:nil];


Isn't that wrong? Can you really pass a selector to a NSString argument? The compiler is complaining, and the program crashes when I attempt.

Yeah it is wrong. I believe you just pass a string with the same contents as what you would put in @selector.
