Question

在Swift 2.0中有谁能告诉我如何在我的UITabBar图标中覆盖Xcode的默认灰色？这个问题没有为我解决：Tab bar item icons appear darker。

Answer 1

在我的第一个视图控制器的viewDidLoad中，我放置了以下内容，它就像一个魅力：

    let aTabArray: [UITabBarItem] = (self.tabBarController?.tabBar.items)!

    for item in aTabArray {
        item.image = item.image?.imageWithRenderingMode(UIImageRenderingMode.AlwaysOriginal)
        item.imageInsets = UIEdgeInsetsMake(7, 0, -7, 0)
    }

Answer 2

你需要为UITabBarItem设置颜色，否则你必须设置In UITabBarItem以及需要为UITabBarItem设置imageInsets，如UITabBarItem

.fail(function(error) {
  console.log(error); //logs "Couldn't save all" or "Couldn't save the challenge"
});

和imageInset：

let customTabBarItem:UITabBarItem = UITabBarItem(title: nil, image: UIImage(named: "favorites.png")?.imageWithRenderingMode(UIImageRenderingMode.AlwaysOriginal), selectedImage: UIImage(named: "favorites_h.png")?.imageWithRenderingMode(UIImageRenderingMode.AlwaysOriginal))

UITabBar栏项目图标默认为灰色？
