ios - Add controller to UITabBarController without new item appearing in the tab bar -


i have application uitabbarcontroller main controller.

when user taps button(not in tab bar, other button), want add new uiviewcontroller inside uitabbarcontroller , show it, don't want new uitabbaritem appear in tab bar. how achieve such behaviour?

i've tried set tabbarcontroller.selectedviewcontroller property view controller not in tabbarcontroller.viewcontrollers array, nothing happens. , if add view controller tabbarcontroller.viewcontrollers array new item automatically appears in tab bar.

update

thanks levi, i've extended tab bar controller handle controllers not present in .viewcontrollers.

@interface maintabbarcontroller : uitabbarcontroller  /**   * setting property, tab bar controller display  * given controller added viewcontrollers , activated  * icon not appear in tab bar.  */ @property (strong, nonatomic) uiviewcontroller *foreigncontroller;  @end   #import "maintabbarcontroller.h"  @implementation maintabbarcontroller  - (void)tabbar:(uitabbar *)tabbar didselectitem:(uitabbaritem *)item {   self.foreigncontroller = nil; }  - (void)setforeigncontroller:(uiviewcontroller *)foreigncontroller {   if (foreigncontroller) {     cgfloat reducedheight = foreigncontroller.view.frame.size.height - self.tabbar.frame.size.height;     foreigncontroller.view.frame = cgrectmake(0.0f, 0.0f, 320.0f, reducedheight);      [self addchildviewcontroller:foreigncontroller];     [self.view addsubview:foreigncontroller.view];   } else {     [_foreigncontroller.view removefromsuperview];     [_foreigncontroller removefromparentviewcontroller];   }    _foreigncontroller = foreigncontroller; }  @end

the code correctly set "foreign" controller's view size , remove when user choose item in tab bar.

you either push (if have navigation controller) or add it's view visible view controller's view , add child view controller also.
