tableview 部分的其他标准?

Other criteria to tableview's section?

我想问我是否可以将 "criteria" 而不是 "FirstCharacter" 和 "FullString" 与 "section.criteria" 一起用于表格视图部分。

例如,我需要选取 "section.property" 的前两个字符来提取一些数据并对其进行排序。

我有 属性“12:30”,我想提取“12”以在行部分显示它,而不仅仅是选择第一个字符“1”。

我没有找到,但我希望有解决办法。

docs:

section.criteria holds the criteria for forming each section based on section.property. This value can be one of:

ViewSection.FullString (default) - sections are created based on the section.property value.

ViewSection.FirstCharacter - sections are created based on the first character of the section.property value (for example, 'A', 'B', 'C' sections, etc. for an address book)

A case insensitive comparison is used when determining section boundaries.

或许您可以向您的模型添加一个新角色(例如,'sectionRole')并将其用于对视图中的项目进行分组?
