Is it possible to increase the UITableView separator line thickness?
提问by Kex
I have looked everywhere. Trying to increase the thickness of this line. Is there anyway to do this programmatically? Thanks

The only way of doing it, is setting the separtorStypeto UITableViewCellSeparatorStyleNoneand then you have two options:
唯一的方法是将separtorStype设置为UITableViewCellSeparatorStyleNone然后你有两个选择：
- Create a custom UITableViewCellwith the separator inside it or
- Create an alternate UITableViewCellwith the separator you want and place inside every other cells. If you want to display 3 rows on your table, you should display 5 instead with the alternate cell in rows 2 and 4.
- 创建一个带有分隔符的自定义UITableViewCell或
- 使用您想要的分隔符创建一个备用UITableViewCell并将其放置在每个其他单元格内。如果要在表格中显示 3 行，则应显示 5 行，并在第 2 行和第 4 行中显示备用单元格。

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)
}
}

My solution to this was to add an extension to either UIView or a UITableViewCell.
我对此的解决方案是向 UIView 或 UITableViewCell 添加扩展。
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))
} }
Then use it within your custom TableViewCell or any View you would like to add a bottom line to.
然后在您的自定义 TableViewCell 或您想要添加底线的任何视图中使用它。
override func awakeFromNib() {
super.awakeFromNib()
// Initialization code
self.addSeparator(ofHeight: 1)
}

Set the table separatorsType to UITableViewCellSeparatorStyleNone and configure a cell backroundView with bg color as you like it for the separators and a subview with which to mask it as much as you want. Something like this:
将 table separatorsType 设置为 UITableViewCellSeparatorStyleNone 并根据需要为分隔符和子视图配置带有 bg 颜色的单元格 backroundView ，并根据需要对其进行屏蔽。像这样的东西：
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;
