How to define launch screen storyboard image size in universal application in iOS?

Question

I had a universal iPhone application in which i am decided to use launch screen storyboard instead of launch images.

Now i added a full screen image view on to it then i need an image of size 1x,2x,3x to fill that image view.

i am very much confused about the size of the image i need to add in assets.was it like 600*600(1x),2x,3x according to it .

but on that case image is showing as stretched,Can anybody help me on this ?

Answer 1

you can put all size images in assets . add new image set in it and select attribute inspector and check iphone and ipad from checkbox and uncheck universal. so you are able to put images for iphone and ipad both separately. Hope this will help :)
