Question

I have 2 tabbars in my tabbar controller. I am currently in the second tabbar, after I click on a ‘done’ button, the tabbar controller needs to switch to the first tab and auto refresh the tableview in it.

I am able to execute on the first part

//Switch to the first tab's view
self.tabBarController.selectedViewController 
              = [self.tabBarController.viewControllers objectAtIndex:0];

However I need some advise on how to refresh the first view’s tableview immediately after the switch is made. Any advise is appreciated.

EDIT: Updated requirement

Note: I do not want the view in the tabbar to reload everytime someone clicks on the tab. The reload should only happen in tab 1’s tableview when

1) User is in tab 2

2) User clicks on ‘Done button’ in tab 2

3) App switches to tab 1 + Reloads the tableview in tab 1

Rationale is that the user will update some information in tab 2 which can only be viewed in tab 1. I want the user to be able to view the updated info immediately after switching to tab 1.

Answer 1

You can send NSNotification after

pressing done button on second tab

and handle this notification on first tab controller.
