animation - ios - Expand table view cell like Twitter app -

i want have same behavior twitter app when selecting tweet : expanding row , adding supplementary content.

so not basic row resize. think need 2 different custom cells, did :

- (uitableviewcell *)tableview:(uitableview *)tableview cellforrowatindexpath:(nsindexpath *)indexpath { if ([indexpath compare:self.selectedindexpath] != nsorderedsame) { firstcell *cell = [tableview dequeuereusablecellwithidentifier:@"firstcell"]; if (!cell) { cell = [[firstcell alloc] initwithstyle:uitableviewcellstyledefault reuseidentifier:@"firstcell"]; } cell.firstnamelabel.text = [[self.items objectatindex:indexpath.row] objectforkey:@"firstname"]; homecoming cell; } else { secondcell *cell = [tableview dequeuereusablecellwithidentifier:@"secondcell"]; if (!cell) { cell = [[secondcell alloc] initwithstyle:uitableviewcellstyledefault reuseidentifier:@"secondcell"]; } cell.firstnamelabel.text = [[self.items objectatindex:indexpath.row] objectforkey:@"firstname"]; cell.lastnamelabel.text = [[self.items objectatindex:indexpath.row] objectforkey:@"lastname"]; homecoming cell; } } - (cgfloat)tableview:(uitableview *)tableview heightforrowatindexpath:(nsindexpath *)indexpath { if ([indexpath compare:self.selectedindexpath] == nsorderedsame) { homecoming 80.0; } else { homecoming 44.0; } } #pragma mark - table view delegate - (void)tableview:(uitableview *)tableview didselectrowatindexpath:(nsindexpath *)indexpath { self.selectedindexpath = indexpath; [tableview reloaddata]; }

my problem here want maintain fluid animation twitter app not case because of [tableview reloaddata] (which mandatory think since have 2 different custom cell).

so knows workaround needed or maybe knows how twitter app handling animation stuff ?

you want reload cell animation:

[tableview beginupdates]; [tableview reloadrowsatindexpaths:[nsarray arraywithobject:indexpath] withrowanimation:uitableviewrowanimationfade]; [tableview endupdates];

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...
