前言
整理iOS下的设备常用分辨率、尺寸和缩放因子，方便查阅使用。
- 1 inch = 2.54cm = 25.4mm
- @2x即1个Point被渲染成1个2x2的像素矩阵，即某个方向上1pt存在2px
- PPI（Pixel Per Inch by diagonal）：沿着对角线每英寸所拥有的像素数目。如iPhone 6s的PPI如下计算表示：
iPhone设备
- 放大模式下，iPhone 6分辨率为640x1136(Upsampling，插值采样)，iPhone 6 Plus/6s plus分辨率为1125×2001(Downsampling，缩减像素采样)。
- iPhone 6 plus/6s plus的实际分辨率是1920x1080，实际缩放为@2.46x。（也就是说实际上应该用@2.46x的素材。iOS 拿到@3x绘制结果，实时地再缩小到实际的1080 x 1920分辨率，Downsampling）详见知乎上的讨论。
