为什么我的iOS8应用程序操作扩展应用程序图标不显示？
问题描述：
我的应用程序图标只是一个灰色的超椭圆形，即使我在我的目标应用程序图标和启动图像中指定了一个图标资产目录。
My app icon is just a grey super ellipse even though I have specified a icon asset catalog in my Targets App Icons and Launch Images.
答
您的主应用程序中的资产目录无法从您的应用程序扩展中访问，因为它们是两个单独的应用程序包，只能共享Frameworks。
Your asset catalog in your main application isn't accessible from your application extension as they are two separate applications bundles that can only share Frameworks.
您需要在动作扩展文件夹中创建一个单独的资产目录，并在目标中引用该目录。
You will need to create a separate asset catalog in your action extensions folder and reference that one in your Targets.
