A string is a collection and there are a rich set of methods for iterating 
over a collection. Bring up method search tool (ALT+Shift+W or 
WorldMenu->windows->find message names) and enter "includes" you will find 
methods like includes:, includesAnyOf:, includesAllOf:, anySatisfy: and so 

The Method search tool is a really nifty tool for searching out methods.
