The @2x image is not loaded on iPad retina

Question

i've been writing an app for iPad. I used 2 images, menuBar.png and menuBar@2x.png, on for normal and the other for retina. When i run on simulator, it's perfect. But when i built and run on iPad 3, it seems doesn't load the retina image. Can anyone give me a solution or show me where i go wrong?

Answer 1

The image should be called:

iPhone non-retina: menuBar.png

iPhone retina: menuBar@2x.png

iPad non-retina: menuBar~ipad.png

iPad retina: menuBar@2x~ipad.png

if not named liked this, it will fall back to the iPhone non-retina image
