Question

I have one scenario here, and maybe someone could enlighten me at this corner stone. I have a singleton where initially my json is getting parsed, and I am loading the contents from there to my Data Model.

Now lets say I deep copy from singleton to my data model, is there anyway to transverse the information back to the singleton when information changes in my data model? At current I am doing some brute forcing to update my data model and singleton objects to keep consistency, but I simple think this is a bad approach.

There would be some better way to reverse deep copy somehow, but just trying to see my options here.

Thanks

You should probably look into KVO, i.e. the mechanism that enables bindings or CoreData.

Definitely check the Apple docs – but for a quick starter have a look at
Observing an NSMutableArray for insertion/removal
