推荐答案

`你可以创建一个行类（自定义UIView）并让每个列元素（单独的UILabel）由用于填充的数据设置它。然后，您可以拥有一个表类，以便您可以使用最长的字符串并调整每列的位置。这种方法会给你很多控制，但额外的工作。

`You could make a row Class (custom UIView) and have each "column" element (separate UILabel) set by the data used to populate it. You could then have a table Class so that you could use the longest string and adjust the positioning of the each column. This approach would give you a lot of control, but extra work.

或者使用NSAttributedString和制表位。

Or use NSAttributedString with tab stops.

let myText = "A\t34\nB\t11\nC\t5\nD\t3"
let paragraphStyle = NSMutableParagraphStyle()
paragraphStyle.tabStops = [NSTextTab(textAlignment: NSTextAlignment.Left, location: 150, options: [:])]
paragraphStyle.headIndent = 150
label.attributedText = NSAttributedString(string: text, attributes:[NSParagraphStyleAttributeName: paragraphStyle])

您可以计算循环中最长的字符串宽度，以确定 headIndent 应该是什么是。但是，这不允许右列在您的示例中右对齐。你会得到类似的东西：

You can calculate the longest string width in a loop to determine what the headIndent should be. However, this wouldn't allow for the right column to be right-aligned like in your example. You would get something like:

A        34
B        11
C        5
D        3
