An alternative option to those already presented:
Since you've tested that it responds to the selector, you could typecast like so
if ([(id)response statusCode] == 200)
and thereby not make other assumptions about the class besides whether or not it responds to statusCode, which you know it does.

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)? _______________________________________________
