现在,我使用黑/白png作为我的图标,并在用户选择时使用tintColor。我觉得这太简单了。
我想使用多色图像(已选中),然后使用相同图像的灰度版本(未选中时)
如何为每个TabBar项目使用两个图像?
答案 0 :(得分:1)
创建UITabBarController
的子类,并将图标图片设置为UITableBarItem
viewDidLoad()
子类中的UITabBarController
。
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
let tabBar: UITabBar = self.tabBar
let tabBarItem1: UITabBarItem = tabBar.items![0]
let tabBarItem2: UITabBarItem = tabBar.items![1]
tabBarItem1.image = UIImage.init(named: "tab_icon_1_normal")?.imageWithRenderingMode(UIImageRenderingMode.AlwaysOriginal)
tabBarItem2.image = UIImage.init(named: "tab_icon_2_normal")?.imageWithRenderingMode(UIImageRenderingMode.AlwaysOriginal)
tabBarItem1.selectedImage = UIImage.init(named: "tab_icon_1_selected")?.imageWithRenderingMode(UIImageRenderingMode.AlwaysOriginal)
tabBarItem2.selectedImage = UIImage.init(named: "tab_icon_2_selected")?.imageWithRenderingMode(UIImageRenderingMode.AlwaysOriginal)
}
