Block Delegates

Often I find myself implementing the same delegate protocol over and over. Consider, for example, the Facebook SDK for iOS. I’d like to make lots of requests to the Graph API, and not have a single callback method request:didLoad: in a single class that looks like: -(void)request:(FBRequest*)request didLoad:(id)result { if (request == mainRequest) { // handle result } else if (request == subRequest1) { // handle result } else if (request == anotherRequest) { // handle result } //.
