Issue with launch image in iPhone 6S plus and iPhone 7 plus

Question

I am quite new to Xcode. I have certain images for launch screen of my app. I have added them using drag and drop to the icons (Images.xassets -> LaunchImage).

All of them works properly in all devices except iPhone 6s plus and iPhone 7 plus.

My contents.json file looks like this

{

 "images" : [
{
  "orientation" : "portrait",
  "idiom" : "iphone",
  "extent" : "full-screen",
  "scale" : "1x"
},

  "extent" : "full-screen",
  "scale" : "2x"
},

],
"info" : {

}

I am using Xcode 8 and deployment target is iOS 10.0

Any help would be appreciated

Answer 1

change your

{
  "extent" : "full-screen",
  "idiom" : "iphone",
  "subtype" : "736h",
  "filename" : "iOS_portrait_1080x1920.png",
  "minimum-system-version" : "8.0",
  "orientation" : "portrait",
  "scale" : "3x"
},

to

{
  "extent" : "full-screen",
  "idiom" : "iphone",
  "subtype" : "736h",
  "filename" : "iOS_portrait_1242x2208.png",
  "minimum-system-version" : "8.0",
  "orientation" : "portrait",
  "scale" : "3x"
},

and make sure your image iOS_portrait_1242x2208.png resolution is really 1242x2208 .
