Question

I have upgraded my current target to iPad and made a universal app and the time for adjusting my iphone app to ipad would decrease significantly if there is an answer for this question.

By this time everybody know that if you have a image called “football.png” and want support for Retina Display you should double the size of the image and call it “[e-mail]“.

My question is if there is something for iPad like *football@iPad_which_is_another_size.png*?

If there isn’t a way to do this, do I have to connect every image to an IBOutlet and set the frame programmatically?

Answer 1

In iOS 4.0 and later, it is possible
to mark individual resource files as
usable only on a specific type of
device
To associate a resource file with a
particular device, you add a custom
modifier string to its filename. The
inclusion of this modifier string
yields filenames with the following
format:

 <basename><device>.<filename_extension>

To load the iPad specific resources you should use ~ipad. Example: create the image named AwesomeImage~ipad.png and load with [UIImage imageNamed:@"AwesomeImage.png"] like you do for retina display image.
