i am trying to overwrite the NSURLConnection Delegate but i dont know where to start, can someone please give some more kind of informations and a little bit sample code?

I want to extend the connectionDidFinishLoading delegate. And keep looking if the JSON-String i am becoming back got some error reporting for the user.

it seems to me the best way to extend the delegate. It is even possible?

Answer 1

Extending a protocol will let you add methods to it. However, if you add more methods to <NSURLConnectionDelegate>, that won’t mean that NSURLConnections will use them 🙂

Why can’t you put your error checking code in your connectionDidFinishLoading method i.e.

- (void)connectionDidFinishLoading:(NSURLConnection *)connection {
    // Check your json here
}
