使用Swift将删除线添加到iOS 11中的NSAttributedString [英] Adding strikethrough to NSAttributedString in iOS 11 with Swift

问题描述

在删除线正常工作方面存在一些问题.目前，我正在执行以下操作:

Having some issues getting strikethrough to work. Currently I'm doing the following:

theString.addAttributes([
        NSAttributedStringKey.strikethroughStyle: NSUnderlineStyle.styleSingle.rawValue, 
        NSAttributedStringKey.strikethroughColor: UIColor.white
    ], range: NSMakeRange(0, 1))

虽然没有显示任何删除线.有任何想法吗?我似乎找不到任何有效的方法.

It's not showing any sort of strikethrough though. Any ideas? I can't seem to find anything that works.

推荐答案

我用它来删除Xcode9/iOS11/Swift4 env中的文本

I use this to strike through a text in Xcode9/iOS11/Swift4 env

  let strokeEffect: [NSAttributedStringKey : Any] = [
        NSAttributedStringKey.strikethroughStyle: NSUnderlineStyle.styleSingle.rawValue,
        NSAttributedStringKey.strikethroughColor: UIColor.red,
    ]

   let strokeString = NSAttributedString(string: "text", attributes: strokeEffect)
