iOS App-适用于wCompact hRegular的LaunchScreen.storyboard

Question

I'm trying to help out a colleague with the launch screen storyboard for iOS devices and we're running into a really odd issue.

Whenever we set the size class through Xcode the background image is always fullscreen and the logo always sits in the middle of the screen no matter what, but when we publish the app and test it on an iPhone 4s or 5c (don't have a 5 to hand) the logo is double the size specified in the width and height of the imageView tag in the XML.

The background image and logo are centered correctly on an iPhone 6, 6 plus and iPad 4th Gen.

Does anyone know if I need to offset the position of the logo by 1/2 to compensate for retina?

因此，对于我来说，解决此问题的方法是将大小类设置为wAny hAny，并将约束条件设置为水平和垂直中心对齐，并限制纵横比并将徽标设置为固定大小。
