iOS UICollectionView 特殊单元格顺序

Question

我有一个包含 5 个元素的简单 Collection View 。单元格的默认顺序如下所示:

我想知道是否可以更改单元格的填充\顺序以获得这样的结果:

Answer 1

选项 1:(清洁选项)

您应该有2 个部分。

• 第 1 节有 3 个单元格

• 第 2 部分有 2 个单元格

然后您可以 adjust the inset 使用 collection View(_: layout: inset For Section At: ) 为您要调整的部分。 (在本例中为第 2 节)

If you do not implement this method, the flow layout uses the value in its section​Inset property to set the margins instead. Your implementation of this method can return a fixed set of margin sizes or return different margin sizes for each section.

Section insets are margins applied only to the items in the section. They represent the distance between the header view and the first line of items and between the last line of items and the footer view. They also indicate they spacing on either side of a single line of items. They do not affect the size of the headers or footers themselves.

选项 2:(意大利面选项，但很高兴知道)

为第 2 部分项目创建一个自定义子类，您可以在其中自定义 UICollectionViewCell contentView subview 的实际内容的插入。

然后在第 2 部分中，返回您的自定义单元格。
