Categories but no Protocol?
I really enjoyed the refresher on C & Objective-C taught by Mr. Turner. It left me scratching my head as to why there was no video on Protocols, as they are pretty much woven into everything Apple supplies us with in the Developer resources? Can anyone explain the difference to me as to when I might want one and not the other?
