iphone和ipad高清图片命名规则

和iphone是一样的！！

 

刚查了Apple的文档,图片的命名规则如下即可:

Devices with out retina:
ImageName.png - For iPhone/iPod
ImageName~ipad.png -- For iPad

Devices with retina display:
ImageName@2x~ipad.png -- For iPad
ImageName@2x.png - For iPhone/iPod

Applications running in iOS 4 should now include two separate files for each image resource. One file provides a standard-resolution version of a given image, and the second provides a high-resolution version of the same image. The naming conventions for each pair of image files is as follows:

Standard: <ImageName><device_modifier>.<filename_extension>

High resolution: <ImageName>@2x<device_modifier>.<filename_extension>

The <ImageName> and <filename_extension> portions of each name specify the usual name and extension for the file. The <device_modifier>portion is optional and contains either the string ~ipad or ~iphone. You include one of these modifiers when you want to specify different versions of an image for iPad and iPhone. The inclusion of the @2x modifier for the high-resolution image is new and lets the system know that the image is the high-resolution variant of the standard image.
Important When creating high-resolution versions of your images, place the new versions in the same location in your application bundle as the original.
