例如在iPhone3GS中,scale=1,用的图标是50x50pixel(logicalimage.size=50x50point);在iPhone4~6中,scale=2,则需要100×100pixel(logical image.size=50x50point,乘以image.scale=dimensions in pixels),并且命名为icon@2x.png。 如果APP要同时兼容iPhone3GS~iPhone6,则需要提供icon.png/icon@2x.png两种分辨率的图片。

早期的iPhone3GS的屏幕分辨率是320 480（PPI=163），iOS绘制图形（CGPoint/CGSize/CGRect）均以point为单位（measured in points）： 1 point = 1 pixel（Point Per Inch=Pixel Per Inch=PPI）后来在iPhone4中，同样大小（3.5 inch）的屏幕采用了Retina显示技术，横、纵向方向像素密度都被放大到2...
1 point = scale*pixel(在iPhone4~6中,缩放因子scale=2;在iPhone6+中,缩放因子scale=3)。 可以理解为: scale=绝对长度比(point/pixel)=单位长度内的数量比(pixel/point) 为了自动适应分辨率,系统会根据设备实际分辨率,自动给UIScreen.scale赋值,该属性对开发者只读。APP设计师可以忽略。
