我有一个只有几行文字的标签，我想增加两行之间的间距。其他人也有类似的问题，但是解决方案不能解决我的问题。另外，我的标签可能包含也可能不包含段落。我是新来的Swift。有使用情节提要的解决方案吗？还是只能通过NSAttributedString其可能？

回答：

UILabel使用以下代码段将LineSpacing编程添加到您的代码中。

let attributedString = NSMutableAttributedString(string: "Your text")
// *** Create instance of `NSMutableParagraphStyle`
let paragraphStyle = NSMutableParagraphStyle()
// *** set LineSpacing property in points ***
paragraphStyle.lineSpacing = 2 // Whatever line spacing you want in points
// *** Apply attribute to string ***
attributedString.addAttribute(NSParagraphStyleAttributeName, value:paragraphStyle, range:NSMakeRange(0, attributedString.length))
// *** Set Attributed String to your label ***
label.attributedText = attributedString

let attributedString = NSMutableAttributedString(string: "Your text")
// *** Create instance of `NSMutableParagraphStyle`
let paragraphStyle = NSMutableParagraphStyle()
// *** set LineSpacing property in points ***
paragraphStyle.lineSpacing = 2 // Whatever line spacing you want in points
// *** Apply attribute to string ***
attributedString.addAttribute(NSAttributedStringKey.paragraphStyle, value:paragraphStyle, range:NSMakeRange(0, attributedString.length))
// *** Set Attributed String to your label ***
label.attributedText = attributedString

let attributedString = NSMutableAttributedString(string: "Your text")
// *** Create instance of `NSMutableParagraphStyle`
let paragraphStyle = NSMutableParagraphStyle()
// *** set LineSpacing property in points ***
paragraphStyle.lineSpacing = 2 // Whatever line spacing you want in points
// *** Apply attribute to string ***
attributedString.addAttribute(NSAttributedString.Key.paragraphStyle, value:paragraphStyle, range:NSMakeRange(0, attributedString.length))
// *** Set Attributed String to your label ***
label.attributedText = attributedString
