What's the meaning of "App must be built for iOS devices with Retina display" (3 answers)

Closed 8 years ago.

I've heard about and read some of the new regulations from Apple about submitting apps to app store.

Firstly, the new version of my app is nearly done and it supports the 4-inch screen now.

About the UDID regulation, I don't exactly know what it means and am not quite sure whether my app follows the rule, how should I check this?

And before I submit my app, what steps and setting should I do in my project? My last submitting was over 1 year ago with other's help, so I'm not confident in myself.

For example, how many icons do I need in my project? (currently I have icon.png, icon@2x.png, icon-small.png, appIcon-small@2x.png, icon-72.png, and icon-small-50.png).

I just want to be fully prepared to submit my app.

Thanks for any help!

Icon sizes are listed here:

The biggest shock for me, when submitting an app after a hiatus, was the 1024x1024 App Store icon. Who has artwork that big???

You will also need double-resolution screen shots for all device sizes (iPhone 4, iPhone 5, and iPad).

My book has a pretty good checklist of the things you'll need as part of your final preparations before submission:
