如何根据尺寸类别在启动屏幕中显示不同的图像

Question

I have a LaunchScreen.xib that needs to show slightly different logos for different device formats. I understand how to set constraints conditionally using the "Vary for Traits" button, but I also need to replace the actual image set that the UIImageView is using. I know there is some kind of workaround because I have a sample file where this is happening, but I don't know how they achieved it (see the grayed-out images in the screenshot). I cannot use code because this is a launch screen, so any solution needs to be possible with interface builder.

Conditional image use that I would like to replicate

Answer 1

You can have different images for iPhone and iPad (watch, TV) in your asset catalog for one resource.

You can also have different image for different width, height (traits based) and gamut that you specify in the Image drop down in the LaunchScreen.storyboard (see the little plus sign).

I think the latter is what you want.
