Programatically switching tabs using selectedViewController property

Question

I've used search already, haven't found an answer.

Trying to switch like this:

[self. tabBarController.selectedViewController OptionsViewContorller];

and like this:

 [self.tabBarController.selectedViewController = self.tabBarController.viewControllers     objectAtIndex:3];

but it doesn't work, i also tried and advice to change

self.tabBarController.selectedIndex

but it only changes at tab bar not a view.

which version of iOS sdk you using? – Wubao Li Mar 09 '12 at 11:52 — Wubao Li, Mar 09 '12 at 11:52

This should work.

self.tabBarController.selectedViewController = [self.tabBarController.viewControllers objectAtIndex:3];

it just changes selected icon it tab bar but it doesn't change view. – Horhe Garcia Mar 09 '12 at 12:00
@HorheGarcia is the icon changed to correct. if the icon and the tab index is right, check the selected view controller. Does you tap the tab index, it behaves right? – Wubao Li Mar 09 '12 at 13:28
i found the problem, my tab tab is situated in another controller. From that controller it works ok, how can i access it from another controller? – Horhe Garcia Mar 10 '12 at 09:34
@HorheGarcia use delegation pattern to interact between controllers – Wubao Li Mar 10 '12 at 16:42

// this code i am using to switch to tabbar view controller 0, first view controller.

self.tabBarController.selectedIndex = 0;

UIViewController *controller = [self.tabBarController.viewControllers objectAtIndex:0];
if ([controller isKindOfClass:[UINavigationController class]]) {
    [((UINavigationController*)controller) popToRootViewControllerAnimated:false];
}

[self.navigationController popToRootViewControllerAnimated:true];

If you want to switch from your UITabBarController class, you have to write this code in -viewDidAppear:animated:

[((UIViewController *) self.viewControllers[0]).tabBarController setSelectedIndex:1];

Hope this help.

for swift 4+

you have to get reference to the tab before the view was presented

let tab = self.presentingViewController as! UITabBarController
self.dismiss(animated: true, completion:{ 
     tab.selectedIndex = 2
})

// viewControllerIndex is an int describing the position of the viewController
// in the tab bar array index
[self.tabBarController setSelectedIndex:viewControllerIndex];

it just changes selected icon it tab bar but it doesn't change view. – Horhe Garcia Mar 09 '12 at 11:51
If the tab bar icon is changing it sounds like it IS changing the view controller - are you sure the views in your tab bar are **distinct** enough to recognise them changing? – Damo Mar 09 '12 at 12:02
they are absolutely different. why it may be so? icon becomes active but views doesn't change.. – Horhe Garcia Mar 09 '12 at 12:08
its best if you refer to Tabster, included with ios documentation. there must be something you are doing wrong. – JOA80 Mar 09 '12 at 12:13
