iphone - Facebook Ios sdk logging in -

i trying create function ios facebook sdk able login , if logged in able see nslog string "logged in". not seeing string @ all. also, login seems working fine in terms of pushing button , seeing facebook app , pressing ok continue. can inform me on doing wrong?

-(ibaction)popbutton:(id)sender { tuappdelegate *appdelegate = (tuappdelegate *)[[uiapplication sharedapplication] delegate]; // button's job flip-flop session open closed if (appdelegate.session.isopen) { // if user logs out explicitly, delete cached token information, , next // time run applicaiton presented log in ux again; // users close app or switch away, without logging out; // cause implicit cached-token login occur on next launch of application [appdelegate.session closeandcleartokeninformation]; } else { if (appdelegate.session.state != fbsessionstatecreated) { // create new, logged out session. appdelegate.session = [[fbsession alloc] init]; } // if session isn't open, let's open , nowadays login ux user [appdelegate.session openwithcompletionhandler:^(fbsession *session, fbsessionstate status, nserror *error) { // , here create sure update our ux according new session state [self updateview]; }]; } } - (void)updateview{ // app delegate, can reference session property tuappdelegate *appdelegate = (tuappdelegate *)[[uiapplication sharedapplication] delegate]; if (appdelegate.session.isopen) { nslog(@"logged in"); } else { nslog(@"not logged in"); } }

i suspect you've missed @ to the lowest degree step 2d, wiring openurl facebook sdk:

https://developers.facebook.com/docs/tutorials/ios-sdk-tutorial/authenticate/

... said, have missed more. if seeing app 1 time again after login suspect you've added url scheme info.plist, otherwise check also.

Accessing MATLAB's unicode strings from C -

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...
