xcode 7 - Missing support for Retina 4 in image.xcassets

Question

In xcode 7 there is no option to retina 4 image. I am creating a simple view added background image in my xib file.I have created a image.xcassets of background image added 1x (320 * 480), 2x (640 * 960), 3x ( 1248 * 2208) resolution images. But when i am using this image set on my xib file its only showing a correct image for iphone 4 and iphone 4s. I have changed the mode as Aspectfit.After that it has started showing margins on top and bottom. Please help me.

Thanks in advance

Answer 1

I guess you will need to edit the xcassets json files yourself, or find an editor that can do that for you.

The json format is open and documented by Apple

Answer 2

You will have to add the lines in json file of your image. Follow the below steps:
1. Right click on the image set in images.xcassets, click on show in finder.
2. You will see Contents.json file, open this file and add below code:

{  
      "idiom" : "iphone",
      "filename" : "iphone-5.png",
      "subtype" : "retina4",
      "scale" : "2x"
},

so your final json file will look like the following:

{
 "images" : [
 {
   "idiom" : "iphone",
   "filename" : "iphone-4-normal.png",
   "scale" : "1x"
 },
 {
   "idiom" : "iphone",
   "filename" : "iphone-4-ratina.png",
   "scale" : "2x"
 },
 {
   "idiom" : "iphone",
   "filename" : "iphone-5.png",
   "subtype" : "retina4",
   "scale" : "2x"
 },
 {
   "idiom" : "iphone",
   "filename" : "iphone-6+.png",
   "scale" : "3x"
 }
 ],
 "info" : {
 "version" : 1,
 "author" : "xcode"
 }
}  

3. Save the file and close it. Now in your Xcode there will be 4 sub image set and you can drag the respective image in that.
