I wanted to create a one-stop guide for the icon sizes that are required for any app submitted to the app store and one that is compiled with base sdk iOS 7.x and targeting iPhones and iPad devices. The below table is an exercise for exactly that. Also included is some miscellaneous information that may come in handy.
The ‘Image name’ row is just a file naming convention for the resources that you use for a particular device type.
Although iPhone 5, iPad 3rd and 4th gen are no longer being sold by Apple, I decided to keep them in the table since they use the same set of icons as iPhone 5C/5S and iPad Air respectively (which are being sold by Apple as of this day).
For more information, you can refer to Apple’s own documentation:
