ios5 - how to access a variable from another nib file in ios -

i have 2 view controller files inputviewcontroller , currencyviewcontroller. want access variable declared in inputview within currencyview. designed in empty application project.

you can declare variable globally in appdelegate & can access in both viewcontroller. changes made in variable reflect in both controllers. create variable property of appdelegate.h class eg. @property (strong, nonatomic) nsstring *var; & synthesize in appdelegate.m @synthesize var; declare "appdelegate * appdelegate" in both controllers.h & in controller.m in viewdidload write appdelegate=[[uiapplication sharedapplication]delegate]; variable can accessible using appdelegate.var anywhere in code of both viewcontroller & changes reflected in both. hope work more efficiently need.

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...
