objective c - Properly defining a static NSString* c-style array under ARC -



objective c - Properly defining a static NSString* c-style array under ARC -

in implementation file, have static 2-dimensional c-style array of nsstring* defined as:

static nsstring* thecolorarray[][3] = { [redtype] = {@"red", @"blah", @"yes"}, [bluetype] = {@"blue", @"yadda", @"yes"}, ..... }

the method in question accesses array like:

-(nsstring*)value:(nsinteger)value { homecoming thecolorarray[value][0]; }

this seems work fine 99% of time...but when fails work fails exc_bad_access - kern_invalid_address @ 0x11

i've verified value parameter not beyond bounds of array. seems odd address 0x11...which kind of implies array has not been initialized.

so happening here? there "gotcha" need aware of arc , c-style arrays?

the documentation clear structs cannot contain arc'd objects, argue applies multidimensional array datums well, though doesn't so. did seek this:

static nsstring __unsafe_unretained * thecolorarray[][3] = ...

this take objects allocated here out of arc , remove possibility compiler aggressively nulling shouldn't be.

assuming that's problem. maybe if you're able step debugger, can see symbol beingness dereferenced when errs?

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...
