Question

我到处寻找。试图增加这条线的厚度。无论如何以编程方式执行此操作？感谢

唯一的方法是将separtorStype设置为UITableViewCellSeparatorStyleNone，然后您有两种选择：

创建一个自定义UITableViewCell，其中包含分隔符或
使用您想要的分隔符创建备用UITableViewCell，并将其放在每个其他单元格中。如果要在表格上显示3行，则应显示5而不是第2行和第4行中的备用单元格。

private let kSeparatorId = 123
private let kSeparatorHeight: CGFloat = 1.5

func tableView(tableView: UITableView, willDisplayCell cell: UITableViewCell, forRowAtIndexPath indexPath: NSIndexPath)
{
    if cell.viewWithTag(kSeparatorId) == nil //add separator only once
    {
        let separatorView = UIView(frame: CGRectMake(0, cell.frame.height - kSeparatorHeight, cell.frame.width, kSeparatorHeight))
        separatorView.tag = kSeparatorId
        separatorView.backgroundColor = UIColor.redColor()
        separatorView.autoresizingMask = [.FlexibleWidth, .FlexibleHeight]

        cell.addSubview(separatorView)
    }
}

我的解决方案是为UIView或UITableViewCell添加扩展名。

extension UIView {

func addSeparator(ofHeight height : CGFloat) {
    let lineView = UIView()
    lineView.backgroundColor = .red
    self.addSubview(lineView)
    let constraintString = "V:|-\(self.frame.size.height - height)-[v0(\(height))]|"
    self.addConstraintsWithFormat("H:|[v0]|", views: lineView)
    self.addConstraintsWithFormat(constraintString, views: lineView)
}

//MARK: - Constraints Extension

func addConstraintsWithFormat(_ format: String, views: UIView...) {
    var viewsDictionary = [String: UIView]()
    for (index, view) in views.enumerated() {
        let key = "v\(index)"
        view.translatesAutoresizingMaskIntoConstraints = false
        viewsDictionary[key] = view
    }
    addConstraints(NSLayoutConstraint.constraints(withVisualFormat: format, options: NSLayoutFormatOptions(), metrics: nil, views: viewsDictionary))
} }

然后在您的自定义TableViewCell或任何想要添加底线的视图中使用它。

override func awakeFromNib() {
    super.awakeFromNib()
    // Initialization code
    self.addSeparator(ofHeight: 1)
}

将table separatorsType设置为UITableViewCellSeparatorStyleNone，并根据需要为分隔符配置bg颜色的单元backroundView，并根据需要使用子视图对其进行掩码。像这样：

UIView * bg = [[UIView alloc] initWithFrame:cell.bounds];
bg.backgroundColor = [UIColor darkGrayColor];
bg.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth;

UIView * overBg = [[UIView alloc] initWithFrame:CGRectInset(cell.bounds, 0, 4.)];
overBg.backgroundColor = [UIColor whiteColor];
overBg.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth;

[bg addSubview:overBg];
cell.backgroundView = bg;

是否可以增加UITableView分隔线的厚度？
