Let’s assume your TabbarController instance is in appDelegate. When you dismiss the modalView, you post a notification. Your app delegate will be observing this notification and when it receives it, it will call [myTabController setSelectedIndex:2]; Following could be the code:

// modalViewController
-(void)dismiss
{
   //your regular code
   [[NSNotificationCenter defaultCenter] postNotificationName:@"modalDismissed" object:nil];
}
//appDelegate
-(void)applicationDidFinish....
{
  //your regular code
  [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(selectAnotherTab)   name:@"modalDismissed" object:nil];
}
-(void)selectAnotherTab
{
   [myTabController setSelectedIndex:2];
}
