Answer 1

I'm not totally sure what you want to do, but it looks to me like you want to do a HTTP GET request, so check out NSURLConnection that will help you having it correctly formatted and executed

You should try using NSString stringWithFormat

Example NSString* url = [NSString stringWithFormat:@"http://xxx.xxx.xx/service.asmx?mobilenumber=%@&country=%@&region=%@",strNumber,strCountry,strRegion];

You can insert many strings into one string by using the %@ parameter.
