how to customize tabbar items which is added on storyboard - ios

Question

I made UITabbar controller and make 5 tabbar buttons on Storyboard.
But I cannot control image sizes and colors in tabbar items.
And I want to customize button colors and shapes using PNG files, not using default colors.
But the below code is not working at well except tabbar tintcolor.
class MainView: UITabBarController {
override func viewDidLoad() {
super.viewDidLoad()
tabBar.barTintColor = UIColor.white
}
override func tabBar(_ tabBar: UITabBar, didSelect item: UITabBarItem) {
switch item.tag{
case 0:
print(item.tag)
UITabBar.setItems(item[0]) = UITabBarItem(title: "Magzine", image: UIImage(named: "exhibiter.png"), selectedImage: UIImage(named: "exhibiterselected.png"))
case 1:
print("")
case 2:
print("")
case 3:
print("")
case 4:
print("")
default:
break
}
}
override func viewWillAppear(_ animated: Bool) {
UIApplication.shared.isStatusBarHidden = false
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
}

you can use like this
class TabBarViewController: UITabBarController {
required init(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)!
override func viewDidLoad() {
super.viewDidLoad()
UITabBar.appearance().tintColor = UIColor(red: 254/255.0, green: 105/255.0, blue: 51/255.0, alpha: 100.0)
for i in 0 ..< self.tabBar.items!.count {
switch i {
case 0:
tabBar.items?[0].title = "Home"
let firstTab = self.tabBar.items![i] as UITabBarItem
learnTab.image = UIImage(named: "Homedeselected")!.imageWithRenderingMode(UIImageRenderingMode.AlwaysOriginal)
firstTab.selectedImage = UIImage(named: "Homedeselected")!.imageWithRenderingMode(UIImageRenderingMode.AlwaysOriginal)
firstTab.imageInsets = UIEdgeInsetsMake(-1, 0, 1, 0)
firstTab.titlePositionAdjustment = UIOffsetMake(0, -4)
case 1:
tabBar.items?[1].title = "Request"
let secondTab = self.tabBar.items![i] as UITabBarItem
secondTab.image = UIImage(named: "RequestDeselected")!.imageWithRenderingMode(UIImageRenderingMode.AlwaysOriginal)
secondTab.selectedImage = UIImage(named: "Requestselected")!.imageWithRenderingMode(UIImageRenderingMode.AlwaysOriginal)
secondTab.imageInsets = UIEdgeInsetsMake(-1, 0, 1, 0)
secondTab.titlePositionAdjustment = UIOffsetMake(0, -4)
case 2:
tabBar.items?[2].title = "Renew"
let thirdTab = self.tabBar.items![i] as UITabBarItem
thirdTab.image = UIImage(named: "RenewDeSelected")!.imageWithRenderingMode(UIImageRenderingMode.AlwaysOriginal)
thirdTab.selectedImage = UIImage(named: "RenewSelected")!.imageWithRenderingMode(UIImageRenderingMode.AlwaysOriginal)
thirdTab.imageInsets = UIEdgeInsetsMake(-1, 0, 1, 0)
thirdTab.titlePositionAdjustment = UIOffsetMake(0, -4)
case 3:
tabBar.items?[3].title = "ReSell"
let forthTab = self.tabBar.items![i] as UITabBarItem
forthTab.image = UIImage(named: "ReSellDeSelected")!.imageWithRenderingMode(UIImageRenderingMode.AlwaysOriginal)
forthTab.selectedImage = UIImage(named: "ReSellSelected")!.imageWithRenderingMode(UIImageRenderingMode.AlwaysOriginal)
forthTab.imageInsets = UIEdgeInsetsMake(-1, 0, 1, 0)
forthTab.titlePositionAdjustment = UIOffsetMake(0, -4)
case 4:
tabBar.items?[4].title = "ReCycle"
let fifthTab = self.tabBar.items![i] as UITabBarItem
fifthTab.image = UIImage(named: "ReCycleDeSelected")!.imageWithRenderingMode(UIImageRenderingMode.AlwaysOriginal)
fifthTab.selectedImage = UIImage(named: "ReCycleSelected")!.imageWithRenderingMode(UIImageRenderingMode.AlwaysOriginal)
fifthTab.imageInsets = UIEdgeInsetsMake(-2, 0, 2, 0)
fifthTab.titlePositionAdjustment = UIOffsetMake(0, -5)
default:
break
}
}
}
override func tabBar(tabBar: UITabBar, didSelectItem item: UITabBarItem) {
}
}
