Type Declaration With Protocol

Subject: Type Declaration With Protocol
From: Richard Somers <email@hidden>

The Objective-C 2.0 Programming Language documentation indicates that a type declaration for an object including a formal protocol should look something like this.

    id <Protocol> anObject;

I have been studying some sample code that does it like this.

    NSObject <Protocol> *anObject;

What is the difference between the two?

Richard
