How to remove the selectionIndicatorImage for the middle UITabBarItem

Question

I'm using the custom UITabBarItem image for the middle item, so I have to make an UIImage for selectionIndicatorImage. According to this answer Same question as mine I've made the code.

Code

UIStoryboard *iPhoneSB = [UIStoryboard storyboardWithName:@"Main_iPhone" bundle:nil];
UITabBarController *tbc = [iPhoneSB instantiateInitialViewController];
self.window.rootViewController = tbc;
tbc.delegate = self;

tbc.selectedIndex = 2;

UITabBar *tb = tbc.tabBar;

NSArray *items = tb.items;
for (UITabBarItem *tbi in items) {
  UIImage *image = tbi.image;
  tbi.selectedImage = [image imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
  tbi.image = [image imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
}
[tbc.tabBar setSelectionIndicatorImage:[UIImage imageNamed:@"selected-tabbar-bg.png"]];

And the delegate method:

- (void)tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UIViewController *)viewController {

    if (tabBarController.selectedIndex==2) {
        [tabBarController.tabBar setSelectionIndicatorImage:nil];
    } else {
        [tabBarController.tabBar setSelectionIndicatorImage:[UIImage imageNamed:@"selected-tabbar-bg.png"]];
    }
}

It works, thanks to the answer. But there is some issue. selectionIndicatorImage is still nil after the first touch inside any UITabBarItem (sure except the middle).

For example:

On the app launch third UITabBar is selected. Touch at first item - selectionIndicatorImage works good (first item became selected). Touch at third item (particular item) - there is no selectionIndicator (it's good). But after that if I touch for example first - there is no selectionIndicator too. It appears if I touch second after that. Where I was wrong? Thanks in advance.

Put logs in your delegate methods and also check that in your project, your are setting selectionIndicatorImage as nil.

 - (void)tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UIViewController *)viewController { 

 if(tabBarController.tabBar.selectionIndicatorImage == nil)
     NSLog("Starting point delegate: Selection indicator image is nill");
 else 
     NSLog("Starting Point Of delegate: Selection indicator image is available");

 if (tabBarController.selectedIndex==2) {
     [tabBarController.tabBar setSelectionIndicatorImage:nil];
 } else {
     [tabBarController.tabBar setSelectionIndicatorImage:[UIImage imageNamed:@"selected-tabbar-bg.png"]];
 } 

 if(tabBarController.tabBar.selectionIndicatorImage == nil)
     NSLog("Ending point delegate: Selection indicator image is nill");
 else 
     NSLog("Ending Point Of delegate: Selection indicator image is available");
   }
