you didn't start request. need:

[connection start];

or

nsurlconnection *connection = [[nsurlconnection alloc] initwithrequest:request delegate:self startimmediately:yes];

edit: comment below had incorrect method name. try implementing both:

- (void)connection:(nsurlconnection *)connection didreceiveresponse:(nsurlresponse *)response

and

- (void)connection:(nsurlconnection *)connection didfailwitherror:(nserror *)error

and see if either of being hit.
