演示如何使用UICollectionView，这是一种以类似网格的方式向用户呈现有序数据的方法。通过集合视图对象，可以定义嵌入视图的表示和排列。集合视图类与附带的布局对象密切合作，以定义单个数据项的位置。在这个示例中，uikit提供了一个基于流的标准布局对象，您可以使用它来实现包含标准大小项目的多列网格。
Demonstrates how to use UICollectionView, a way to present ordered data to users in a grid-like fashion. With a collection view object, you are able to define the presentation and arrangement of embedded views. The collection view class works closely with an accompanying layout object to define the placement of individual data items. In this example UIKit provides a standard flow-based layout object that you can use to implement multi-column grids containing items of a standard size. (2019-04-04, Objective-C, 10370KB, 下载0次)
