iPhone 5 / 5C / 5S的图像文件

Question

I have some png image files in my project's Supporting Files directory that are intended to be shown only in iPhone 5 and later devices (I detect screen size programmatically to set the proper image). This would be a simple question: since all those devices have retina display, should I suffix image files with @2x ? Even if no standard resolution of such images will be needed?

Thanks

如果该应用程序旨在用于iPhone5 / 5S / 5C，那么我认为没有必要检测“大小”，因为它们都是相同的大小，但是如果您要制作的应用程序可以在具有以下功能的设备上使用diff大小，然后在2x图像的图像文件名末尾附加“ @ 2x”，并在开发时使用不带.png扩展名的图像名称... API会自动设置适当的图像。不需要检测尺寸等。
