这句话是解释 iOS 7 的设计初衷。
英文原文是：
True simplicity is derived from so much more than just the absence of clutter and ornamentation. It’s about bringing order to complexity.
新的 iOS 不仅仅是移除了过多的拟物纹理，更重要的是，以有序有层次的方式呈现信息。
Ive接着解释：
iOS 7 is a clear representation of these goals. It has a whole new structure that is coherent and then it’s applied across the entire system.
We’ve considered the tiniest details, like refining the typography, to much larger ones like redesigning all the icons, and developing a grid system allowed us to achieve a much more harmonious relationship between individual elements. We’ve also incorporated awhole new palette of colors.
Distinct, functional layers help establish hierarchy and order, and the use of translucency gives you a sense of your context. These planes combined with new approaches to animation and motion; create a sense of depth and vitality. The iPhone responding to your movements drives the parallax to create a whole new experience of depth.
iOS 7 使用了调整过的字体，重新设计图标，并引入网格系统，再加上半透明的功能层，这些元素使信息的呈现更统一，且更有层次感。
问题里的那句话，就是对以上解释的一句提纲挈领的描述。
