Switching UITabBarController tabs from a separate UIViewController

Question

I have a view that has a couple of buttons and I have a tab bar view controller with two different tabs. When I press one of the buttons in the view controller I want to jump to a specific tab in the tab bar view controller.

How would I go about this?

This is different because the buttons are not in the tab view or tab bar controller. They are in a completely different view. — bnjmn.myers, Aug 16 '13 at 16:11
Either edit to include those details and try to get it re-opened, or ask a question that makes those details clear. Your question now focuses on selecting a certain tab rather than dealing with the complexity of communicating with a tab bar controller from a view controller that's not in one. — Carl Veazey, Aug 16 '13 at 18:06
I apologize I should have said I have view CONTROLLER and a tab bar view controller. — bnjmn.myers, Aug 16 '13 at 19:32

Or just `self.tabBarController.selectedIndex = 1;`. Same thing. Also, note that we're assuming here that this code lives in the view controller -- view controllers have a `tabBarController` property. – Caleb Aug 16 '13 at 15:17
The buttons and the tabs are in two different view controllers. – bnjmn.myers Aug 16 '13 at 15:31
If they are in separate view controllers "self" wont work will it? – bnjmn.myers Aug 16 '13 at 15:32
yes they will not work. because self means this, current object or in this case UIViewController – Usman Ahmad Aug 16 '13 at 15:35
That's what I thought. I need to transition from one view to another while selecting a specific tab. Not simply jumping between tabs. – bnjmn.myers Aug 16 '13 at 15:38
Any other suggestions? – bnjmn.myers Aug 16 '13 at 15:45
Can you pass a reference to the tabBarController to this new controller and use the above method? – Justin Paulson Aug 16 '13 at 16:23
I've tried this in viewDidLoad, viewDidAppear and initWithNibName and it always loads on the first tab. – bnjmn.myers Aug 20 '13 at 17:06
how you are going from one view to another? – Usman Ahmad Aug 26 '13 at 10:38
you can use prepareForSegue and in this method you can assign a property of the destination Controller may be a tab id 0,1,2,3.. and then in destination controller in viewDidLoad method just select that tab – Usman Ahmad Aug 26 '13 at 10:38
