取消Header悬停

自定义Section Header头部UIView

public class MASectionNoHoverHeaderView: UIView
{
    weak var tableView:UITableView?
    var section:Int = 0

    public override var frame: CGRect {
        didSet {
            if let tableView = tableView {
                super.frame = tableView.rectForHeader(inSection: section)
            }
        }
    }
}

Section分组圆角和设置下划线

设置tableView的两个参数，才能设置separator

tableView.separatorInset = .zero
tableView.layoutMargins = .zero

继承UITableViewCell，设置cell左右间距

public class MAAutoWidthCell:UITableViewCell{
    public override var frame: CGRect{
        didSet{
            var newFrame = frame
            newFrame.origin.x = 16
            newFrame.size.width = UIScreen.width - 32
            super.frame = newFrame
        }
    }
}

通过UITableViewDelegate,设置圆角，和设置下划线缩进

public func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) {
    let count = self.tableView(tableView, numberOfRowsInSection: indexPath.section)
    cell.layer.cornerRadius = 8
    cell.clipsToBounds = true
    cell.layer.maskedCorners = []
    if indexPath.row == 0 {
        cell.layer.maskedCorners.update(with: [.layerMinXMinYCorner, .layerMaxXMinYCorner])
    }
    cell.separatorInset = UIEdgeInsets(top: 0, left: 16, bottom: 0, right: 0)
    if indexPath.row == count - 1 {
        cell.layer.maskedCorners.update(with: [.layerMinXMaxYCorner, .layerMaxXMaxYCorner])
        cell.separatorInset = UIEdgeInsets(top: 0, left: cell.frame.width, bottom: 0, right: 0)
    }
}
