一般来说你只需创建2组图像。你原来的，然后一个新的两倍大的名字@ 2x。因此，对于大小为32x32的image.png，你会得到一个大小为64x64的分辨率为image@2x.png的两倍。在你的应用程序中，只需在Interface Builder中使用image.png并在代码中加载。
In general you just create 2 sets of images. Your original and then a new one twice as big with @2x in the name. So for image.png at size 32x32 you would have one that is twice the resolution called image@2x.png at size 64x64. In your app just always use the image.png in Interface Builder and when loading in code.
无需检测设备。这些图像将由操作系统自动拾取并根据需要加入。
There is no need to detect the device. These images will automatically be picked up by the OS and subbed in as necessary.
