ios - Finding the cause of memory leak in Instruments -

i have run leaks in instruments , showing me memory leak 100% value. able see line of code causing problem. not sure error is..

- (void) listallbooks { if (marrlistfromdb != nil) { [marrlistfromdb removeallobjects]; marrlistfromdb = nil; } marrlistfromdb = [[nsmutablearray alloc] init]; servercommunicationapi *servapi = [[servercommunicationapi alloc] init]; servapi.delegate = self; nsurl *url = [nsurl urlwithstring:klistcontents]; [servapi listbookswithdeviceid:singleton.g_strdevid devicekey:singleton.g_strdevid andsessionstring:singleton.g_strsessionid sessionkey:@"sessionkey" url:url andrequestmethod:@"post"]; }

the line of error lastly one. not sure why causing memory leak... need guidance..

it hard tell info provided, maybe delegate property of servercommunicationapi declared (strong)? in case servapi never released, because keeps strong reference (retain cycle). suggest check in instruments kind of object leaks, create reply much easier.

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...
