This may seem like a dumb question, but how do you call a method in a
CustomClass from another method in the same CustomClass??

Eg.
              CustomClass has 2 methods.
              - helloThere
              - seeYouTommorow

              When I'm in, or done with, helloThere, how can I call
              seeYouTommorow from within helloThere?

I hope someone can help.
Thanks

As you name your methods - hello.. ( and not + hello...) I suppose you don't  
mean messages that are sent to Classes but messages to objects.

This is easy done by using the global id self, that points always to the object  
of the method you're in. Just do the following:

- helloThere
{
	....
	[self seeYouTomorrow];
	...
	return self;
}
- seeYouTomorrow
{
	....
	return self;
}
