iphone - present a UIviewcontroller programmatically from UINavigationController with Storyboard -

my question: how can switch between viewcontrollers 1 rootnavigationcontroller in code, while maintaining customization set in storyboard , data load in viewcontrollers?

currently implementing remenu, provides simple dropdown tableview change views with. when 1 of cells pressed in dropdown, want switch view. example, if press "home", want go masterviewcontroller method switch views called within rootnavigationcontroller.m, , looks following:

remenuitem *homeitem = [[remenuitem alloc] initwithtitle:@"home"                                                 subtitle:@"return home screen"                                                    image:[uiimage imagenamed:@"icon_home"]                                         highlightedimage:nil                                                   action:^(remenuitem *item) {                                                        uistoryboard *sb = [uistoryboard storyboardwithname:@"mainstoryboard" bundle:nil];                                                        uinavigationcontroller *vc = [sb instantiateviewcontrollerwithidentifier:@"mynewtableview"];                                                   //     vc.modaltransitionstyle = uimodaltransitionstylecrossdissolve;                                                       [self presentviewcontroller:vc animated:no completion:nil];                                                   }]; 

clearly, however, wrong implementation, because ignores ui customization made in storyboard, datacontroller invoke in masterviewcontroller.m on matter appreciated!
