objective c - SplitViewController's master side sometimes is not rendered correctly when changing orientation in IOS 6.1 -

i have tab bar controller has tabitems. of tabitems splitviewcontrollers. sometimes, when alter orientation, left side of splitview controller not render correctly, have black square in bottom. changing orienation again, problem solved.

there nil special in code. in viewdidload have:

[self.navigationcontroller setnavigationbarhidden:yes]; self.splitviewcontroller.delegate = self;

and 1 splitviewcontroller delegate method handled trivially:

- (bool)splitviewcontroller:(uisplitviewcontroller *)svc shouldhideviewcontroller: (uiviewcontroller *)vc inorientation:(uiinterfaceorientation)orientation { homecoming no; }

i have nil more, tableview on cells on detail side.

i've seen such issue , workaround came reset size of left side view controller's view , it's navigation controller's view:

- (void)didrotatefrominterfaceorientation:(uiinterfaceorientation)frominterfaceorientation { if (self.splitviewcontroller) { viewheight = ... navviewheight = ... cgrect viewframe = cgrectmake(0, 0, 320, viewheight); self.view.frame = viewframe; cgrect navcontrollerviewframe = cgrectmake(0, 0, 320, navviewheight); self.navigationcontroller.view.frame = navcontrollerviewframe; } }

where viewheight , navviewheight can calculate screen height depending on current orientation (which has been set when didrotatefrominterfaceorientation: called). guess these values should equal you hide navigation bar.

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...
