How do I change the preview device in Xcode storyboard?
提问by Bhargav
As you can see from the below image
如下图所示
The storyboard preview is of some tablet device, I need to change this to the latest iphone or iphone 4s, how can I do this? Also I know about the assistant editor and how to preview on multiple devices using the assistant editor, thats not what I want, I want to change the preview in the story board itself
故事板预览是某些平板设备的，我需要将其更改为最新的 iphone 或 iphone 4s，我该怎么做？我也知道助理编辑器以及如何使用助理编辑器在多个设备上进行预览，这不是我想要的，我想更改故事板本身的预览
