ios - How to Add iPhoneX Launch Image

Question

Using Xcode Version 9.0 (9A235), I am trying to add a Launch Image for iPhoneX at the requested 2436px × 1125px (landscape). Currently I am using a Storyboard and it looks like this:

'launchimage' is an Image View linked to an Image Set:

And the Image Set is as follows:

The only place I get an iPhoneX sized image is in a Launch Image set:

But when I try to select a Launch Image in the Image View on the storyboard it can't be selected:

Any help on how to add the correct sized launch image for iPhoneX or is it back to Launch Images? I would prefer the correct sized image, not a stretched one.

UPDATE:

I would like to explain why I want the image to be exactly the same pixel per pixel. Following the Guidelines in https://developer.apple.com/ios/human-interface-guidelines/icons-and-images/launch-screen/ my launch image is a static version of the first page of the App. If the Launch Image is stretched then there is a noticeable switch from Launch Image to First Page. Which sort of defeats the object of the guidelines. Apple recommend using a storyboard launch, but it seems you can't follow their guidelines if you do. Typical, really.

Answer 1

If your used the LaunchImage.launchimage for Launch, the solution is (in Xcdoe 9.0):

1. Select Assets.xcassets, right click on middle pane, select App Icons & launch Images -> New iOS Launch Image . Then move the old LaunchImage.launchimage images to the new one, and add the image size with 1125×2436 px for the iPhoneX.

2. Also, you can add the following json object to Contents.json file which on LaunchImage.launchimage folder in your old project。Once Xcode refreshes, just drop in a 1125×2436px image. If you need landscape, you can add another with the orientation.

{
      "extent" : "full-screen",
      "idiom" : "iphone",
      "subtype" : "2436h",
      "minimum-system-version" : "11.0",
      "orientation" : "portrait",
      "scale" : "3x"
    }
