Get an ivar or property from a NSString

Question

Can we get an ivar or a property from a NSString like we can get a class from a NSString with the function NSClassFromNSString() ?

Just wondering: what would you need this for? What use is it? — Itai Ferber, Jun 08 '11 at 23:50
Yes, I could change my design pattern but I just want to know if it is possible. — klefevre, Jun 08 '11 at 23:53

For any properties you can just use [object valueForKey:myString] and it'll be done. This can also find ivars in certain situations.

I’ve posted an answer to [this question](http://stackoverflow.com/q/5784875/557219) showing how to obtain ivars using the Objective-C runtime. – Jun 09 '11 at 00:04

There are a number of functions in the Objective-C Runtime that let you get the list of ivars, properties, and methods associated with a given class, and then to get information about individual ivars, properties, and methods. Take a look at the Objective-C Runtime Reference.

Nice list of functions but that was not exactly what I needed, thanks anyway. – klefevre Jun 09 '11 at 00:14
