iOS resizableImageWithCapInsets & @2x, @3x images

Question

I am creating a 'chat bubble' using this method, by setting the background image after calling resizableImageWIthCapInsets . However, for this method you need to hardcode the cap insets by pixel, but the pixel size is different for each 1x, 2x, and 3x image size. How do I get around this issue? Is there a way to know which image the device is using (the 1x, 2x, or 3x)?

You don't need to do it in code. Xcode has a special tool for this. Check this link , in the section named "CAN I GET THOSE IMAGES FOR THESE BUTTONS, BUT LONGER?" or here . There are explanations how to use it.

If you use this you can not care if image is ready to display or which resolution you should use.
