Question

Im making a universal app for iPhone and iPad, both retina and non retina displays.

I’ve looked around the web for the answer and have found conflicting answers, im not sure why some people say the default image for ipad has to be 2008 (h) rather than 2048.

Anyway, I want to know what Default.pngs I need to include with my app for the load screen. And whether each one is essential or not? Also what name each one should be called?

Thanks

Answer 1

The launch images section of the iOS Image and Design Guidelines explains this in detail.

For iPhone and iPod touch launch images, include the status bar
region. Create launch images of these sizes:

320 x 480 pixels 640 x 960 pixels (high resolution)

For iPad launch images, do not include the status bar region. Create launch images of
these sizes:

• For portrait:

  • 768 x 1004 pixels
  • 1536 x 2008 pixels (high resolution)

• For landscape:

  • 1024 x 748 pixels
  • 2048 x 1496 pixels (high resolution)

I also had to ask this question on ux.stackexchange.com recently, but found the above link later.

EDIT: Naming of these files is described here. Important parts from the text are following:

Every app must provide at least one launch image. This image is
typically in a file named Default.png that displays your app’s initial
screen in a portrait orientation. However, you can also provide other
launch images to be used under different launch conditions. All launch
images must be PNG files and must reside in the top level of your
app’s bundle directory. The name of each launch image indicates when
it is to be used, and the basic format for launch image filenames is
as follows:

<basename><usage_specific_modifiers><scale_modifier><device_modifier>.png
