所以您要隐藏UITableViewCells之一?

So you want to hide one of your UITableViewCells?

我认为最简单的方法是向行数据数组"中添加更多信息.

Ill think the easiest way is to add some more information to your "Row Data Array".

例如:

您有10列，并且您想隐藏4个特定列".您有一个名为"getRowData"的函数-此函数将返回(当未选择过滤器时)所有10行.当您点击按钮时，您可以更改"getRowData"函数以仅返回所需的4行.

You have 10 Columns, and you want to hide 4 Specific Column. You have a function called "getRowData" - this returns (when no filter is selected) all 10 Rows. When you tap on a button, you could change your "getRowData" function to return only the 4 Rows you want.

在上面显示的示例中-您需要基于UITableViewController的一些可折叠列表.

With the example you showed above - you want some collapsible Lists, based on an UITableViewController.

因此，您有3个主要类别(在此示例中)-如果用户单击一个标题"，则要展开该类别的列表.

So you have (In this example) 3 Main Categories - and if the User click on one "Title" you want to expand the list for this Category.

因此您可以使用Sections-为每个类别创建一个Section.然后执行以下操作:

So you could use Sections - create a Section for each Category. Then implement something like this:

//为激活的类别"创建一个主变量

// create a main variable for your "activated Category"

var enabledCategory:Int = 0 // you could add i base value

override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {

        let indexPath = tableView.indexPathForSelectedRow();

        enabledCategory = indexPath.row;
....

在此处检查用户单击了哪个部分.如果(例如，"0"-因此是第一个，请展开此部分.因此，请执行以下操作:

Check here which section was clicked by the user. If (for example "0" - so the first one, expand this section. So do something like this:

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {

    if(indexPath.section == enabledCategory) {
        return rows // return rows you want to show
    }

您还需要在此处更改行数:

You need also to change the count of rows in here:

override func numberOfSectionsInTableView(tableView: UITableView) -> Int {

    return 3
}

在您的示例中，该值应始终为3.

this should be (in your example) always 3.

override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {

这取决于您的部分//类别

This depends on your section // Category
