Answer 1

-sendSynchronousRequest:returningResponse:error: gives you a way to get an error right there in the method itself. That last argument is really (NSError **) error; that is, a pointer to an NSError pointer. Try this:

NSError        *error = nil;
NSURLResponse  *response = nil;

[NSURLConnection sendSynchronousRequest: req returningResponse: &response error: &error];

if (error) {...handle the error}
