viewForHeaderInSection宽度错误 [英] viewForHeaderInSection incorrect width

问题描述

headerView的宽度不适合屏幕的宽度. 我的viewForHeaderInSection函数:

Width of my headerView does not adapt to the width of the screen. My viewForHeaderInSection function:

func tableView(tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
    let cell = self.tableView.dequeueReusableCellWithIdentifier("sectionCell") as! sectionCell
    cell.hint.text = "some name"

    cell.tag = section


    let singleTap = UITapGestureRecognizer(target: self, action: #selector(singleTapOnSection(_:)))

    cell.addGestureRecognizer(singleTap)

    let view = UIView(frame: cell.frame)

    view.addConstraints(cell.constraints)

    view.addSubview(cell)

    return view
}

我必须将单元格添加到UIView(或类似的东西)，因为我在该节中隐藏了行. 我认为我必须以编程方式在查看"中添加一些约束，但是我不知道如何

I must add cell to the UIView (or something similar) because i have hiding of row in the section. In my opinion i must add to "view" some constraints programmatically, but i dont know how

推荐答案

定义customView: UITableViewHeaderFooterView类，并在View Controller的viewDidLoad:中编写

Define a customView: UITableViewHeaderFooterView class, and in viewDidLoad: of View Controller write

tableView.registerClass(customView.classForCoder(), forHeaderFooterViewReuseIdentifier: "HeaderIdentifier")

而不是使单元出队，而是使UITableViewHeaderFooterView出队(因为这是正确的方法).

And instead of dequeueing a cell, dequeue a UITableViewHeaderFooterView (as it is the right way to do it).

这样，您必须在代码中添加自动布局或在 nib 文件中定义自动布局，如果您使用的是这种方法，那么与nib一起工作并处理各种事情会让人感到沮丧.使用此库 NibDesignable .

This way you have to add auto layout in code or define it in a nib file, working with nibs and handling all kinds of things is kinda frustrating, if you're using this approach i suggest use this library NibDesignable.
