iphone - splitview controller loaded in portrait and then to landscape -

i dynamically removing view , adding splitviewcontroller. have problems in landscape mode. when same loading in landscape mode view first loaded in portrait , turning landscape mode. there way solve problem. there temporary flickering , ux not pleasing.

i ran similar problem earlier today, removed previous views had added uiwindow, added other viewcontroller resolved issue, so;

-(void)loginwassuccessful {      // discard login view controller, , nil out     [self.loginviewcontroller_ipad.view removefromsuperview];     self.loginviewcontroller_ipad = nil;      self.splitviewcontroller.view.hidden = no;     self.splitviewcontroller.view.alpha = no_alpha;      // create animation block that'll fade out splash view, , fade in split view controller (that houses employee search)     [uiview animatewithduration:login_to_emp_search_fade_animation_duration animations:^{             // remove , nil splash , login view window...         self.splashview.alpha = no_alpha;         self.splitviewcontroller.view.alpha = full_alpha;      }]; 

hope helps!
