ios - Swift iOS 如何选择数据到一个表

问题描述

如果 status 等于 static 我不想在表格中显示它，我该怎么做？代码如下。我只想显示所有数据，而不是status == "static".

Response [["status": {
    name = static;
}, "sched": 2015-01-01T08:00:00+08:00, "desc": Brush your teeth, "id": 249, "reward": 1.00, "parent": , "child": , "date_created": 2018-04-25T14:27:20.405928+08:00, "name": aBrush your teeth, "occurrence": {

解决方案

首先，如果您不想显示单元格，则不应创建它。如果你是，你正在打不必要的额外电话。

如果您当前在 处返回数据源的总数numberOfRowsInSection，则必须status != "static"改为返回项目数。这样，cellForRowAt将被称为正确的次数。

然后，您有 2 个选项：

  1. 有一个单独的数据源，其中不包含带有的项目，status == "static"并直接在cellForRowAt;处使用它。
  2. 在 处过滤cellForRowAt您当前的数据源，使其仅返回正确的项目。
