Question

如何在 Xcode 7 的 Interface Builder 中设置和显示自定义占位符背景？

此功能是 added in Xcode 7 , 但我无法设置它。

Background placeholders on custom views and other containers can be hidden on the Interface Builder canvas by selecting Editor > Canvas > Show Background Placeholders. (20580948)

我已经启用但没有任何改变，而且我找不到可以设置自定义占位符图像的位置:

几年后，Xcode 10 仍然没有提供您当时想到的任何灵 active 😐

来自 Xcode 10 文档:

Use placeholder backgrounds to identify image views, MapKit views, MetalKit views, GLKit views, and SceneKit views. Hide the placeholder backgrounds to focus on the content of your own views.

Choose Editor > Canvas > Show Placeholder Backgrounds to toggle showing placeholder backgrounds for certain types of views on the Interface Builder canvas.

该功能实际上仅限于 仅 Apple 的一些内置 View (甚至那些蓝色背景颜色仍然几乎是硬编码的 View )。
