Bundling retina images only in iOS apps

5 Solutions Collect From Internet About “Bundling retina images only in iOS apps”

The only non-retina images needed for an iOS app is the icon and the default image.

For all in-app images, it’s fine to bundle retina versions only and let non-retina devices scale them down. I’ve done it myself on a few occasions to get below the cellular network download limit on App Store and I’ve never been rejected because of that.

Of course, not providing non-retina images may decrease performance and image quality on older devices due to the required down-scale operations, but that may be fine if you really need to decrease the app size.

No, you can’t, e.g. the Icon is required in Non-Retina and for the App Store are Retina-Screenshots required, too.

You can test if Retina-Images will automatically resized if there is no Non-Retina available but I can’t say if your app will be rejected or not.

Update: As Retterdesdialogs mentioned, Retina-Images will be resized to Non-Retina, but it’s not recommend and I highly recommend to not do this!

Yes, you can use the larger images, but this could lead to a slower performance if the number of images on the screen is too big.

IPhone 4/4S uses 2x the image dimensions of an iPhone 3GS. If you supply only retina images then the image will be twice the size that it should be on the iPhone 3GS.

You must keep separate images for both iphone 3 and iphone 4 and if the app is in the iphone 4 you can use the images with double the resolution of iphone 3 images.
