NSAttributedString：非段落标题

Question

我正在构建一个字典，其中包含一个大的UITextView，每个单词都有多个NSAttributedString。我正在尝试在如下行之前设置一个固定空格，但我无法在以“L'ensemble”开头的文本上设置标题，因为它不是段落（不是以 \n 开头）。

您有实现这一目标的想法吗？

到目前为止，这是我的代码，它不起作用，因为 valueParaStyle 没有做任何事情，因为 valueText 不以 \n 开头。

谢谢。

let senseNumberParaStyle = NSMutableParagraphStyle()
senseNumberParaStyle.paragraphSpacingBefore = 20

let valueParaStyle = NSMutableParagraphStyle()
valueParaStyle.firstLineHeadIndent = 20
valueParaStyle.headIndent = 20

for i in 0..<senses.count {
    let senseNumberText = NSAttributedString(string: "\n\(i + 1).", attributes: [
        NSFontAttributeName: UIFont(name: "AvenirNext-Bold", size: 14)!,
        NSForegroundColorAttributeName: UIColor(red: 1, green: 0.275, blue: 0.294, alpha: 1),
        NSParagraphStyleAttributeName: senseNumberParaStyle
    ])

    wordText.appendAttributedString(senseNumberText)

    if let value = senses[i].value {
        let valueText = NSAttributedString(string: " \(value)", attributes: [
            NSFontAttributeName: UIFont(name: "AvenirNext-Regular", size: 15)!,
            NSForegroundColorAttributeName: UIColor(red: 0.2, green: 0.2, blue: 0.2, alpha: 1),
            NSParagraphStyleAttributeName: valueParaStyle
        ])

        wordText.appendAttributedString(valueText)
    }
}

你在正确的轨道上。您只需在第一行添加"\t"：

 var paragraphStyle = NSMutableParagraphStyle()
 paragraphStyle.headIndent = 20

 label.attributedText = NSAttributedString(string: "1.\tHere comes your text. Indent as you really want it", attributes:[NSParagraphStyleAttributeName : paragraphStyle])

没有"\t":

与"\t":
