如何控制UILabel中的行间距 [英] How to control the line spacing in UILabel

问题描述

当在UILabel中放置多行时，是否可以减少文本之间的差距？我们可以设置框架，字体大小和＃行。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 # of lines. I want to reduce the gap between the two lines in that label.

推荐答案

我想为此答案添加新内容，我不觉得那么坏...这是一个 Swift 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

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

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

简答：你不能。文本行，您将必须子类化UILabel并滚动自己的drawTextInRect，或创建多个标签。

"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."
