Answer 1

I had the same issue and I solved by inserting the UITabBar item with this code:

UITabBar *tabBar = self.tabBarController.tabBar;
    UITabBarItem *tabBarItem1 = [tabBar.items objectAtIndex:0];
    UITabBarItem *tabBarItem2 = [tabBar.items objectAtIndex:1];
    UITabBarItem *tabBarItem3 = [tabBar.items objectAtIndex:2];

    tabBarItem1.image = [[UIImage imageNamed:@"img1.png"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
    tabBarItem2.image = [[UIImage imageNamed:@"img2.png"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
    tabBarItem3.image = [[UIImage imageNamed:@"img3.png"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];

    tabBarItem1.selectedImage = [[UIImage imageNamed:@"img1_sel.png"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];

I added this code to all my view controller (in my case 3) and it create the right image, while selected and not selected. I hope it helps you
