I am relatively new to IPhone coding, although I have reached the point of working on a genuine (hopefully) saleable app.
But one thing that is still mysterious is the responder chain. All the books give passing reference to it, but I have not found one...

This will be a temporary fix until the bugs are fixed.

In the responder chain that is given the opportunity to respond to an event.

Here's the UIApplication API page as an example..

Lately I have been trying out Rails, and I came to love the respond_to.
Is it possible to do something like this in PHP?, responding to different types of requests. So it is easy to implement an alternate way even if javascript is disabled.
