"statusCode" isn't mine, it's a NSHTTPURLResponse selector. The NSURLResponse being sent to the callback is actually an NSHTTPURLResponse--at least, that's the plan :)

My guess would be to make your statusCode part of a formal protocol and then use an explicit cast once you are sure that response implements the protocol.
Alternately, if you are going to use respondsToSelector: to test viability, you could use performSelector: to actually invoke it.

I have code that looks like this
- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
{
if( [response respondsToSelector:@selector(statusCode)] )
{
if( [response statusCode] == 200 )
{
// stuff
}
}
}
When I call [response statusCode] in the code above, CodeWarrior warns that "receiver cannot handle this message." Obviously this was taken care of on the previous line, but I can see how a compiler might not understand this :) How can I placate the compiler and silence the warning (other than disabling warnings)?
