when i do a simple request using twitter api on ipad simulator, why does server send a 401 error while using iphone simulator it seems to work?
i use MGtwitterEngine and SAOauthTwitterEngine. it looks like a common problem but i didn't find any solution throughout the web.
SOLUTION
control the response code in your MGtwitterenginedelegate method implementation if it's 401 you have to launch
[_engine clearAccessToken];
and relaunch login methods.
The device needs to be authenticated separately. Did you go through the OAuth authentication process on the device?
