What are the things in <here> called in a .h file after you declare the interface…
Example (The UIWebViewDelegate part):
@interface ViewController : UIViewController <UIWebViewDelegate> {
They are called “protocols”. The syntax declares that the class conforms to that particular protocol, ie. it implements not only the methods declared in the
ViewControllerclass interface, but also the methods declared in theUIWebViewDelegateprotocol. An Objective C protocol is conceptually similar to a Java interface. There’s a more complete description of protocols at http://developer.apple.com/library/ios/#documentation/cocoa/conceptual/ProgrammingWithObjectiveC/WorkingwithProtocols/WorkingwithProtocols.html
