Question

I am creating a login application. Most of data is generated using a web service. I’ve created a window based app. I would like to implement the rest of my project by placing all of my code in the AppDelegate.

I already have one web service running and now I would like to add another service in my AppDelegate.

Your question is pretty unclear, but there is absolutely nothing stopping you from making multiple NSURLConnections to the web service(s) in question. I mean, for example if you are using SBJSON why not:

NSString *jsonOne = [NSURLConnection sendSynchronousRequest:requestOne returningResponse:&response error:&error];
NSString *jsonTwo = [NSURLConnection sendSynchronousRequest:requestTwo returningResponse:&response error:&error];

NSDictionary *wsDictOne = [self.jsonParser objectWithString:jsonOne error:NULL];
NSDictionary *wsDictTwo = [self.jsonParser objectWithString:jsonTwo error:NULL];

I think you need to expand your question, but no, there is nothing stopping you from calling all the web services you would like.
