Add Runtime Color attribute named "tintColor" from StoryBoard. This is working(for Xcode 8 and above).
从 StoryBoard 添加名为“tintColor”的运行时颜色属性。这是有效的（对于 Xcode 8 及更高版本）。
if you want unselected color.. you can add unselectedItemTintColortoo.
如果你想要未选择的颜色..你也可以添加unselectedItemTintColor。

This elegant solution works great on SWIFT 3.0, SWIFT 4.2and SWIFT 5.1:
这个优雅的解决方案在SWIFT 3.0、SWIFT 4.2和SWIFT 5.1上效果很好：
On the Storyboard:
在故事板上：
- Select your Tab Bar
- Set a Runtime Attibutecalled tintColorfor the desired color of the Selected Iconon the tab bar
- Set a Runtime Attibutecalled unselectedItemTintColorfor the desired color of the Unselected Iconon the tab bar
- 选择您的标签栏
- 为选项卡栏上选定图标的所需颜色设置名为tintColor的运行时属性
- 设置名为unselectedItemTintColor的运行时属性，用于选项卡栏上未选择图标的所需颜色

In Swift, using xcode 7 (and later), you can add the following to your AppDelegate.swift file:
在 Swift 中，使用 xcode 7（及更高版本），您可以将以下内容添加到 AppDelegate.swift 文件中：
UITabBar.appearance().tintColor = UIColor(red: 255/255.0, green: 255/255.0, blue: 255/255.0, alpha: 1.0)
This is the what the complete method looks like:
这是完整方法的样子：
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// I added this line
UITabBar.appearance().tintColor = UIColor(red: 255/255.0, green: 255/255.0, blue: 255/255.0, alpha: 1.0)
return true
}
In the example above my item will be white. The "/255.0" is needed because it expects a value from 0 to 1. For white, I could have just used 1. But for other color you'll probably be using RGB values.
在上面的例子中，我的项目是白色的。“/255.0”是必需的，因为它需要一个从 0 到 1 的值。对于白色，我可以只使用 1。但是对于其他颜色，您可能会使用 RGB 值。

If you want to make all tab bar items the same color(selected & unselected)...
如果您想让所有标签栏项目具有相同的颜色（选中和未选中）...
Step 1
第1步
Make sure your image assets are setup to Render As = Template Image. This allows them to inherit color.
确保您的图像资产设置为Render As = Template Image。这允许他们继承颜色。
Step 2
第2步
Use the storyboard editor to change your tab bar settings as follows:
使用情节提要编辑器更改标签栏设置，如下所示：
- Set Tab Bar: Image Tintto the color you want the selected icon to inherit.
- Set Tab Bar: Bar Tintto the color you want the tab bar to be.
- Set View: Tintto the color you want to see in the storyboard editor, this doesn't affect the icon color when your app is run.
- 将Tab Bar: Image Tint设置为您希望所选图标继承的颜色。
- 将Tab Bar: Bar Tint设置为您希望标签栏的颜色。
- 将View: Tint设置为您希望在故事板编辑器中看到的颜色，这不会影响您的应用程序运行时的图标颜色。
Step 3
第 3 步
Steps 1 & 2 will change the color for the selected icon. If you still want to change the color of the unselected items, you need to do it in code. I haven't found a way to do it via the storyboard editor.
步骤 1 和 2 将更改所选图标的颜色。如果你还想改变未选中项的颜色，则需要在代码中进行。我还没有找到通过故事板编辑器来做到这一点的方法。
Create a custom tab bar controller class...
创建自定义标签栏控制器类...
// TabBarController.swift
class TabBarController: UITabBarController {
override func viewDidLoad() {
super.viewDidLoad()
// make unselected icons white
self.tabBar.unselectedItemTintColor = UIColor.white
}
}
... and assign the custom class to your tab bar scene controller.
...并将自定义类分配给您的标签栏场景控制器。
If you figure out how to change the unselected icon color via the storyboard editor please let me know. Thanks!
如果您想知道如何通过故事板编辑器更改未选择的图标颜色，请告诉我。谢谢！

You can change colors UITabBarItem by storyboard but if you want to change colors by code it's very easy:
您可以通过情节提要更改 UITabBarItem 的颜色，但如果您想通过代码更改颜色，则非常简单：
// Use this for change color of selected bar
// 使用它来改变选定条的颜色
[[UITabBar appearance] setTintColor:[UIColor blueColor]];
// This for change unselected bar (iOS 10)
// 这用于更改未选中的栏（iOS 10）
[[UITabBar appearance] setUnselectedItemTintColor:[UIColor yellowColor]];
// And this line for change color of all tabbar
// 此行用于更改所有标签栏的颜色
[[UITabBar appearance] setBarTintColor:[UIColor whiteColor]];
