If your app shouldn't run natively on iPad devices, or you want the iPad version to show a
proportionally larger portion of the game world, you can change the “ Default scal-
ing from: ” setting to 2x (phonehd). Note that changes to the default scaling are not ap-
plied to existing images, only to new images added to SpriteBuilder henceforth. For our
project, leave this setting at 4x (tablethd).
Caution Apple requires app developers to support Retina resolutions. Apps
have reportedly been rejected for looking “blurry” because they weren't using
Retina-sized images on Retina devices, although Apple seems to be less strict
when it comes to games. Still, I strongly advise against using the Scale from
setting 1x for any image, because it will have noticeably low quality on iPad
Retina devices. The only exception is if you are designing a pixel-art game.
When you later find your app download size has increased too much, consider unchecking
one or more of the publishing target check boxes labeled phone , phonehd , tablet , or
tablethd as needed to reduce the size of the bundle. Here's a quick overview of which
iOS device will load resources from which category:
phone : Used only by iPhone 3GS
phonehd : Used by iPhone 4 and newer iPhones
tablet : Used by non-Retina iPads: iPad 1 and 2, iPad mini first generation
