Just got it done..

   -(void)viewWillAppear:(BOOL)animated{
[super viewWillAppear:animated];
tabBar.delegate = self;
[tabBar setSelectedItem:[tabBar.items objectAtIndex:0]];
[self activateTab:1];
 }

- (void)activateTab:(int)index {
switch (index) {
    case 1:
    //condition
    break;
    case 2:
   //condition
    break;
    default:
        break;
}
 }

  - (void)tabBar:(UITabBar *)tabBar didSelectItem:(UITabBarItem *)item {
NSLog(@"didSelectItem: %d", item.tag);
[self activateTab:item.tag];    
  }
