You should provide the 2x images in your resource too, so as to display them properly on retina device. Please make sure you have both version of images as mentioned & set just the normal-image name. The 2x image is searched in the resource & will be taken automatically while execution.

Its not just the name matters, you should also keep the size of images in 2x ratio. For example if normal image is 32x32 then make sure the 2x image is of size 64x64

Hope this helps.
