The accepted answer's code not work for me.

接受的答案的代码对我不起作用。

Here is code, that works:

这是代码，有效：

    [[UITabBarItem appearance] setTitleTextAttributes:@{ NSForegroundColorAttributeName : [UIColor yellowColor] }
                                             forState:UIControlStateNormal];
    [[UITabBarItem appearance] setTitleTextAttributes:@{ NSForegroundColorAttributeName : [UIColor whiteColor] }
                                             forState:UIControlStateSelected];

I found the answer for my own question.

我找到了我自己问题的答案。

We can set perforamceItem setTitleTextAttributes:for two different states.

我们可以设置perforamceItem setTitleTextAttributes:两种不同的状态。

• forState:UIControlStateNormal
• forState:UIControlStateHighlighted

• forState:UIControlStateNormal
• forState:UIControlStateHighlighted

I added the following code

我添加了以下代码

 [performanceItem setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIFont fontWithName:@"HelveticaLTStd-Roman" size:10.0f], NSFontAttributeName,  [UIColor yellowColor], NSForegroundColorAttributeName,nil] forState:UIControlStateNormal];

[performanceItem setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIFont fontWithName:@"HelveticaLTStd-Roman" size:10.0f], NSFontAttributeName,  [UIColor whiteColor], NSForegroundColorAttributeName,nil] forState:UIControlStateHighlighted];

I need to replace the yellow color with the color of my ICONS. This is how they are looking now.

我需要用我的图标的颜色替换黄色。这就是他们现在的样子。

When More is selected

选择更多时

When Performance is Selected

选择性能时

Code free way to do this:

代码免费的方式来做到这一点：

If you are just using iOS 10 then you may change the Image Tint in your Tab Bar

如果您只使用 iOS 10，那么您可以更改标签栏中的图像色调

If you are also supporting iOS 9 and lower, then you must also add tintColor to your user definer runtime attributes in each tab bar item

如果您还支持 iOS 9 及更低版本，那么您还必须将 tintColor 添加到每个选项卡栏项中的用户定义器运行时属性

if you also wish to change your icon color make sure the correct color image is in your assest folder and change Render as to Original Image

如果您还想更改图标颜色，请确保正确的彩色图像位于您的资产文件夹中，并将渲染更改为原始图像

This is the swift version :-

这是快速版本：-

        for item in self.mainTabBar.items! {

          let unselectedItem: NSDictionary = [NSForegroundColorAttributeName: UIColor.whiteColor()]
          let selectedItem: NSDictionary = [NSForegroundColorAttributeName: UIColor.whiteColor()]
          item.setTitleTextAttributes(unselectedItem as? [String : AnyObject], forState: .Normal)
          item.setTitleTextAttributes(selectedItem as? [String : AnyObject], forState: .Selected)

        }

Or you can simply change in Appdelegate :-

或者您可以简单地更改 Appdelegate :-

 func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    UITabBarItem.appearance().setTitleTextAttributes([NSForegroundColorAttributeName: UIColor.blueColor()], forState: .Selected)
    UITabBarItem.appearance().setTitleTextAttributes([NSForegroundColorAttributeName: UIColor.blackColor()], forState: .Normal)
    // Override point for customization after application launch.
    return true
}

For a swift solution, let type inference be your friend:

对于快速解决方案，让类型推断成为您的朋友：

override func viewWillAppear(animated: Bool) {
  for item in self.tabBar.items! {
    let unselectedItem = [NSForegroundColorAttributeName: UIColor.blackColor()]
    let selectedItem = [NSForegroundColorAttributeName: UIColor.whiteColor()]

    item.setTitleTextAttributes(unselectedItem, forState: .Normal)
    item.setTitleTextAttributes(selectedItem, forState: .Selected)
  }
}

This is easy , simply subclass UITabBarItem and assign it to be the class of your tab bar item in either storyboard or code. The below works perfectly for me.

这很简单，只需将 UITabBarItem 子类化并将其分配为故事板或代码中标签栏项目的类。以下非常适合我。

import UIKit

class PPTabBarItem: UITabBarItem {
    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
        commonInit()
    }
    override init() {
        super.init()
        commonInit()
    }

    func commonInit() {
        self.setTitleTextAttributes([NSFontAttributeName: UIFont.systemFontOfSize(13), NSForegroundColorAttributeName:UIColor.blackColor()], forState: UIControlState.Normal)

        self.setTitleTextAttributes([NSFontAttributeName: UIFont.systemFontOfSize(13), NSForegroundColorAttributeName:UIColor.yellowColor()], forState: UIControlState.Selected)
    }
}

skywinder's solution is good but it triggers global scope.

skywinder 的解决方案很好，但它触发了全局范围。
