当我在UITextView中显示如下：

但我想在UITextView中显示它：

我怎么做？

Answer 1

您可以在每个新行\t

之后使用\n

＆＃34; 1. \ tTitle One。\ n1.1。\ t这是第一行的第一行......这是第二行。\ n2。\ t标题二。\ n \ t这是标题二的内容＆＃34;

Answer 2

使用属性字符串。但它相当冗长：

let indent: CGFloat = 36.0

let bodyParagraphStyle = NSMutableParagraphStyle()
bodyParagraphStyle.firstLineHeadIndent = indent
bodyParagraphStyle.headIndent = indent

let headerParagraphStyle = bodyParagraphStyle.mutableCopy() as! NSMutableParagraphStyle
headerParagraphStyle.firstLineHeadIndent = 0
headerParagraphStyle.tabStops = [NSTextTab(textAlignment: .Left, location: indent, options: [:])]

let bodyAttributes = [NSParagraphStyleAttributeName: bodyParagraphStyle]
let headerAttributes = [NSParagraphStyleAttributeName: headerParagraphStyle]

let text = NSMutableAttributedString()
text.appendAttributedString(NSAttributedString(string: "1\tTitle 1\n", attributes: headerAttributes))
text.appendAttributedString(NSAttributedString(string: "1.1\tThis is line one of content one\n", attributes: headerAttributes))
text.appendAttributedString(NSAttributedString(string: "This is line two\n", attributes: bodyAttributes))
text.appendAttributedString(NSAttributedString(string: "This is line three\n", attributes: bodyAttributes))

self.textView.attributedText = text
