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() ?

Answer 1

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

Answer 2

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.
