如何在 Swift 中的标签栏的标签上显示图像

问题描述

我正在尝试在选项卡栏的选项卡上显示图像，但无法看到图像。 代码：

    @objc func didTapButton() {
         let tabBarVC = UITabBarController()
         let firstGameRoomController = FirstGameRoomController()
         let secondGameRoomController = SecondGameRoomController()
         let thirdGameRoomController = ThirdGameRoomController()
            
         tabBarVC.setViewControllers([firstGameRoomController,secondGameRoomController,thirdGameRoomController],animated:  true)
            
         let items = tabBarVC.tabBar.items
           
            
            
            items![0].image = resizeImage(image:UIImage(named: "c_1")!,newWidth:24);
            items![1].image = resizeImage(image:UIImage(named: "c_2")!,newWidth:24);
            items![2].image = resizeImage(image:UIImage(named: "c_3")!,newWidth:24);
            
            tabBarVC.modalPresentationStyle = .fullScreen
            present (tabBarVC,animated: true)
        }
        func resizeImage(image: UIImage,newWidth: CGFloat) -> UIImage {
    
            let scale = newWidth / image.size.width
            let newHeight = image.size.height * scale
            UIGraphicsBeginImageContext(CGSize(width: newWidth,height: newHeight))
            image.draw(in: CGRect(x: 0,y: 0,width: newWidth,height: newHeight))
            let newImage = UIGraphicsGetimageFromCurrentimageContext()
            UIGraphicsEndImageContext()
    
            return newImage!
        }

class FirstGameRoomController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        view.backgroundColor = .red
        title = "Game Room 1"
        
    }
}

你能告诉我上面的代码有什么问题吗？我尝试过调整图像大小和不调整图像大小。请看截图
