Question

I am at a complete loss because my application icon simply will not register. I’ve tried just about everything and the icon still just will not register. I think it may have to do with the fact that I was trying to re-name my project something else, and perhaps the targets now do not match. Can anybody provide advice on why my icon simply will not show up on the phone?

Thanks

PNG compression is a little algorithm that the compiler performs to cut down on the space images take up in your app. Unfortunately, it has been the Bain of many a programmer’s existence because it often doesn’t de-compress the images once the binary is made and ran. Just set it to NO.

PNG compression also optimizes the PNG’s for an iOS device like so:

1. Extra critical chunk (CgBI).
2. Byteswapped (RGBA –> BGRA) pixel data, presumably for high-speed >direct blitting to the framebuffer.
3. Zlib header, footer, and CRC removed from the IDAT chunk.
4. Premultiplied alpha (color′ = color * alpha / 255).
