ストーリーボードに追加されたタブバーアイテムをカスタマイズする方法

Question

ストーリーボードでUITabbarコントローラーを作成し、5つのタブバーボタンを作成しました。

しかし、タブバーアイテムの画像のサイズや色を制御することはできません。 そして、デフォルトの色を使用せずに、PNGファイルを使用してボタンの色と図形をカスタマイズしたいと思います。

しかし、以下のコードは、タブバーtintcolor以外はうまくいきません。

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() 
} 

}

あなたのタブバーの項目であなたのストーリーボードのデフォルトを選択した画像の両方を設定し、この

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) { 




    } 

}
