iphone - Convert a NSString into a NSArray -



iphone - Convert a NSString into a NSArray -

i received info json web service , converted nsarray. i've saved nsarray in database retrieval @ later date. info in database looks this:

( { responsecount = 2; responsetotal = 8; }, { responsecount = 6; responsetotal = 8; } )

now i'm @ point want take info , turn nsarray. seek doing along lines of

nsarray *responsearray = self.coredatatable.responsearray; //nsstring value

or

nsarray *responsearray = (nsarray *) self.coredatatable.responsearray; //nsstring value

but when runs, nsarray comes no objects in it. ideas wrong?

code clarify info saving process.

coredatatable *coredatatable = [nsentitydescription insertnewobjectforentityforname:@"coredatatable" inmanagedobjectcontext:self.managedobjectcontext]; coredatatable.categoryname = [d objectforkey: @"categoryname"]; coredatatable.responsearray = [d objectforkey: @"responsearray"]; [self.managedobjectcontext save:nil];

iphone objective-c xcode nsstring nsarray

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...
