It would. But I find RestKit extremely bloated. I believe it adds over 40MB to your project bundle. I prefer ASIHTTPRequest and sometimes even just regular NSURLConnection.hm
so for web services Restkit would do the trick
//
And for ResKit, it does add alot, if you add everything you don't need neither. In the end, the app my team and I made (Devoxx 2011 on iPad store), uses RestKit, and even after all the code and high res images, our IPA is less then 6 mb. So I don't really think about that. (and we didn't delete everything we didn't need).
Did you install RestKit using these directions?: https://github.com/RestKit/RestKit/wiki/Installing-RestKit-in-Xcode-4.x
1. Say that I´m don with my app and want say 30 friend to test it before it goes on app store how is this done??
