UILabel中如何控制行距 [英] How to control the line spacing in UILabel

问题描述

在 UILabel 中放入多行时，是否可以减少文本之间的间隙?我们可以设置框架、字体大小和行数.我想减少该标签中两行之间的差距.

Is it possible to reduce the gap between text, when put in multiple lines in a UILabel? We can set the frame, font size and number of lines. I want to reduce the gap between the two lines in that label.

推荐答案

我想在这个答案中添加一些新的东西，所以我感觉没那么糟糕...这是一个 Swift 的答案:

I thought about adding something new to this answer, so I don't feel as bad... Here is a Swift answer:

import Cocoa

let paragraphStyle = NSMutableParagraphStyle()
paragraphStyle.lineSpacing = 40

let attrString = NSMutableAttributedString(string: "Swift Answer")
attrString.addAttribute(.paragraphStyle, value:paragraphStyle, range:NSMakeRange(0, attrString.length))

var tableViewCell = NSTableCellView()
tableViewCell.textField.attributedStringValue = attrString

简短的回答:你不能.要改变文本行之间的间距，你必须继承 UILabel 并滚动你自己的 drawTextInRect，或者创建多个标签."

"Short answer: you can't. To change the spacing between lines of text, you will have to subclass UILabel and roll your own drawTextInRect, or create multiple labels."
