You can also render the image as original from the attributes inspector for the asset file without writing any code
您还可以从资产文件的属性检查器中将图像渲染为原始图像，而无需编写任何代码

You can also set it up directly in Storyboard... Check my answer here: How to set UITabBarItem's unselected tint, ***including system items*** (iOS7)
您也可以直接在 Storyboard 中进行设置...在这里查看我的答案： 如何设置 UITabBarItem 的未选择色调，***包括系统项目***（iOS7）
If you're using Storyboard you can also set both
ImageforBar ItemandSelected ImageforSelected Bar Itemto get unaltered image in tabBar.
如果您使用的是 Storyboard，您还可以同时设置
ImageforBar Item和Selected ImageforSelected Bar Item在 tabBar 中获取未更改的图像。
Alternatively in Assetscatalog, you can select Render As: Original Imagein the attributes of your image (View> Utilities> Show Attributes Inspectoror shortcut ??4(Option + Command + 4))
或者在Assets目录中，您可以选择Render As：Original Image在图像的属性中（View> Utilities>Show Attributes Inspector或快捷方式??4（Option + Command + 4））
