Xcode 4 warning “Expression result unused” for NSURLConnection

When a function returns a result that you don’t need you can cast it to void to eliminate the compiler warning:

(void) [[NSURLConnection alloc] initWithRequest:request delegate:self];

I haven’t used ARC yet so I can’t say if this is a good idea, before ARC you would need to keep this pointer result somewhere so you could release it.
