这一段是接着上面的说设计得巨好，接下来说哪里巨好。顺着这个逻辑可以加一些主语和逻辑词，让它更符合语境。

The clean, logical separation between data source and layout; the clear division between cell, supplementary, and decoration views; the extensive set of layout attributes that are automatically animated... a lot of care and wisdom has been put together with these APIs.

它的接口设计得十分简洁，它的数据源与视图layout的接口逻辑分离，它的Cell、补充视图和装饰视图有着明确的区分，它有着一堆可继承拓展的layout属性，并且每一个layout的属性都可以通过UIKit自动实现动画，大量的细心与智慧才组成了`UICollectionView`的这些接口。
