ios - TableView viewForHeaderInSection 分隔线

Question

我想将分隔线添加到 tableForHeaderInSection 中。目前标题部分 View 的代码为:

func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) {
    if cell.viewWithTag(kSeparatorId) == nil {
        let separatorView = UIView(frame: CGRect(x: 75, y: cell.frame.height - kSeparatorHeight, width: cell.frame.width-90, height: kSeparatorHeight))
        separatorView.tag = kSeparatorId
        separatorView.backgroundColor = UIColor(displayP3Red: 114/256, green: 112/256, blue: 133/256, alpha: 1.0)
        separatorView.autoresizingMask = [.flexibleWidth, .flexibleHeight]
        cell.addSubview(separatorView)
    }
}

输出:

但我想要这个:

[

如何在viewForHeaderInSection处添加行。谢谢。

Answer 1

创建分隔符 View ...

func separatorView(width: CGFloat, inset: CGFloat, color: UIColor?) -> UIView {
    let footerView = UIView(frame: CGRect(x: 0, y: 0, width: width, height: 1))
    footerView.backgroundColor = color

    let insetView = UIView(frame: CGRect(x: footerView.bounds.origin.x, y: footerView.bounds.origin.y, width: inset, height: 1))
    insetView.backgroundColor = UIColor.white
    footerView.addSubview(insetView)
    return footerView
}

使用table view委托(delegate)方法设置分隔符 View

func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
    return separatorView(width: tableView.frame.size.width, inset: tableView.separatorInset.left, color: tableView.separatorColor)
}
