Reflection Tutorial

[Bollywood]

I would love to see a reflection tutorial, if someone skilled enough can make one, and upload it.

It is a very necessary coding skill to have, but well above my current coding skill level.

Any takers....

thanks in advance

I don't know if this is the sort of thing you are looking for, but have you seen the Apple sample code Reflection?

You want computer-sciencey-type reflection, not visual effect?

If all you need are to get member variables from a class based on a string, you can take advantage of "KVC" - key value coding. If your object has a property called "xValue" , you can get its value like so:

NSString *keyName = @"xValue";
NSValue *theVal = [myObject valueForKey: keyName];

If you need to call a method, you can get a selector from the name,
and then call that selector.
SEL aSelector;
aSelector = NSSelectorFromString(@"myMethod:");
[myObject performSelector: aSelector];

Lastly, to init a class from the name, there's a "classNamed:" method in NSBundle.
