On: iOS 7 only is the only sane thing to do

Great points, except for "@2x only." If your app supports iPads, then the iPad 2 and iPad Mini (first generation) are both non-Retina screens and are still available for sale directly from Apple. Given Apple's 3 year support cycles, iOS 10 will be the first iOS that can fully drop support for non-retina displays if the iPad 2 and original iPad mini are discontinued by the end of this year.

Our app is iPhone only, but this is a great point to remember for anyone thinking about dropping the non-retina image.

People with non-retina iPads can and will download your app.

Non-retina iPads use retina assets for iPhone apps.

Ah good too know. I guess that is new in iOS 7.

My memory is fuzzy, but I think it happened around iOS 5.

[guptaneil → mikeash]

Nope, it's an iOS 7 feature. Retina iPads have done this since iOS 5, since that is when the iPad 3 was introduced, but non-retina iPads used non-retina graphics until iOS 7.

That must be my confusion. Thanks for the info.

Unfortunately, an app cannot be made `-568h` only. And -[UIImage imageWithName:] does not support `-568h` infix.

Which is pretty lame considering xcassets supports an image 'subtype' called R4 that's designed for 4" screens.

There's nothing stopping you from swizzling that method for one that does, though. I've done it without any apparent problems.

It's also really trivial to support both retina and non-retina so I don't understand the point at all..
