Objective-C dynamic properties at runtime?

Question

Is it possible to create an Objective-C class that can have an arbitrary number of dynamic properties at runtime?

I want to be able to call mySpecialClass.anyP

Answer 1

Guillaume is right. forwardInvocation: is the way to go. This answer gives some more details: method_missing-like functionality in objective-c (i.e. dynamic delegation at run time)

This has even more details: Equivalent of Ruby method_missing in Objective C / iOS

And these are some other lesser known Obj-C features that might help you: Hidden features of Objective-C
