HI , Just completed one more app and also learned one more thing so i am here to share with you guys. RETINA DISPLAY - This is the good thing that apple introduce it with iphone 4 and your apps quality increase many times when you see the same app on the other platform,But how it is implemented and what are the parameters for the developer end we have to concern about . i)First you have to create the bigger image with the name@2x.png and double the size you want to use and please keep the DPI 326 . ii)Now convert it in the half of its size and the image name will be name.png with the actual size and with DPI 163. These will help you to put the retina display in your ios apps.
Share what you know... Some day it make some one day...
