ios - 标签栏项目图像未显示

Question

我在 Assets 文件夹中有一张图片，但它没有显示在选项卡栏上。正如其他答案所说，我已将“渲染为”设置为“原始图像”，但这并不能解决问题。

class CustomTabBarController: UITabBarController {
override func viewDidLoad() {
    super.viewDidLoad()


    let homeController = HomeController(collectionViewLayout: UICollectionViewFlowLayout())
    let navigationController = UINavigationController(rootViewController: homeController)
    navigationController.tabBarItem.image = UIImage(named:"news_feed_icon")

    viewControllers = [homeController]

    }
}

Answer 1

试试这个。

在viewDidLoad中添加

let customTabBarItem:UITabBarItem = UITabBarItem(title: nil, image: UIImage(named: "news_feed_icon")?.withRenderingMode(UIImageRenderingMode.alwaysOriginal), selectedImage: UIImage(named: "news_feed_icon"))
    self.tabBarItem = customTabBarItem
