Is there a way to make a the UITabBar show just images that fill the entire TabBarItem? I tried simply placing an image and deleting the text in the item's title but the image always appears off-center (the area where the title text was remains and I can't align the image to be over it)
Change image inset of UITabBarItem in UITabBar. You could adjust the image inset to make image bigger, smaller, shift to right etc.
