IOS launch image sizes

Question

The ios App Programming Guide states the following launch image sizes for iPad apps:

1024x748px and 2048x1496px.

Yet in XCode, I am given the following sizes for ipad portrait launch images in the tooltip:

1024x768px and 2048x1536px.

Which should I follow?

note:

the ios human interface guidelines state:

For iPad launch images, do not include the status bar region.

I am confused as to which dimensions I should be following.

Solution 1

The Launch image dimensions are indeed confusing, and require a lot of needless cross reference. In Xcode there is a page where the launch images are drag and drop yet inexplicably lack pix dimensions!!

Through trial and error, Owen Rubin came up with the following dimensions and I made an image for your reference. Please let me know if we've made any errors.

iPad 2x           = 1536 x 2048
iPad 1x           = 1024 x 768    (landscape)

Solution 4

In XCode select the slot for an image with the 'attributes inspector' tab open on the right hand side panel, it will tell you the Expected Size.

Solution 5

user2339310's link from iPhone Development 101 is a great source regarding the iOS launch image size(s). They have made a nice mockup with the specs:

However, Apple has made it quite clear what sizes the launch image(s) should be:
