推荐答案

在您的MainTabbarViewController中

绑定标签栏的出口:

@IBOutlet weak var myTabBar: UITabBar?

 override func viewDidLoad() {
      super.viewDidLoad()

      myTabBar?.tintColor = UIColor.white
      tabBarItem.title = ""

      setTabBarItems()

 }

在此处设置标签栏项的定义方法如下:

set the tabbar items here defined method below:

func setTabBarItems(){

      let myTabBarItem1 = (self.tabBar.items?[0])! as UITabBarItem
      myTabBarItem1.image = UIImage(named: "Unselected")?.withRenderingMode(UIImageRenderingMode.alwaysOriginal)
      myTabBarItem1.selectedImage = UIImage(named: "Selected ")?.withRenderingMode(UIImageRenderingMode.alwaysOriginal)
      myTabBarItem1.title = ""
      myTabBarItem1.imageInsets = UIEdgeInsets(top: 6, left: 0, bottom: -6, right: 0)

      let myTabBarItem2 = (self.tabBar.items?[1])! as UITabBarItem
      myTabBarItem2.image = UIImage(named: "Unselected")?.withRenderingMode(UIImageRenderingMode.alwaysOriginal)
      myTabBarItem2.selectedImage = UIImage(named: "Selected")?.withRenderingMode(UIImageRenderingMode.alwaysOriginal)
      myTabBarItem2.title = ""
      myTabBarItem2.imageInsets = UIEdgeInsets(top: 6, left: 0, bottom: -6, right: 0)


      let myTabBarItem3 = (self.tabBar.items?[2])! as UITabBarItem
      myTabBarItem3.image = UIImage(named: "Unselected")?.withRenderingMode(UIImageRenderingMode.alwaysOriginal)
      myTabBarItem3.selectedImage = UIImage(named: "Selected")?.withRenderingMode(UIImageRenderingMode.alwaysOriginal)
      myTabBarItem3.title = ""
      myTabBarItem3.imageInsets = UIEdgeInsets(top: 6, left: 0, bottom: -6, right: 0)

      let myTabBarItem4 = (self.tabBar.items?[3])! as UITabBarItem
      myTabBarItem4.image = UIImage(named: "Unselected")?.withRenderingMode(UIImageRenderingMode.alwaysOriginal)
      myTabBarItem4.selectedImage = UIImage(named: "Selected")?.withRenderingMode(UIImageRenderingMode.alwaysOriginal)
      myTabBarItem4.title = ""
      myTabBarItem4.imageInsets = UIEdgeInsets(top: 6, left: 0, bottom: -6, right: 0)

 }
