Вот хорошее решение со Swift
let label = UILabel()
label.frame = CGRect(x: 40, y: 100, width: 280, height: 600)
label.textColor = UIColor.lightGray
label.numberOfLines = 0
let arrayString = [
"Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.",
"Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.",
"Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur.",
"Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum."
]
label.attributedText = add(stringList: arrayString, font: label.font, bullet: "")
self.view.addSubview(label)
Добавить атрибуты маркера
func add(stringList: [String],
font: UIFont,
bullet: String = "\u{2022}",
indentation: CGFloat = 20,
lineSpacing: CGFloat = 2,
paragraphSpacing: CGFloat = 12,
textColor: UIColor = .gray,
bulletColor: UIColor = .red) -> NSAttributedString {
let textAttributes: [NSAttributedStringKey: Any] = [NSAttributedStringKey.font: font, NSAttributedStringKey.foregroundColor: textColor]
let bulletAttributes: [NSAttributedStringKey: Any] = [NSAttributedStringKey.font: font, NSAttributedStringKey.foregroundColor: bulletColor]
let paragraphStyle = NSMutableParagraphStyle()
let nonOptions = [NSTextTab.OptionKey: Any]()
paragraphStyle.tabStops = [
NSTextTab(textAlignment: .left, location: indentation, options: nonOptions)]
paragraphStyle.defaultTabInterval = indentation
//paragraphStyle.firstLineHeadIndent = 0
//paragraphStyle.headIndent = 20
//paragraphStyle.tailIndent = 1
paragraphStyle.lineSpacing = lineSpacing
paragraphStyle.paragraphSpacing = paragraphSpacing
paragraphStyle.headIndent = indentation
let bulletList = NSMutableAttributedString()
for string in stringList {
let formattedString = "\(bullet)\t\(string)\n"
let attributedString = NSMutableAttributedString(string: formattedString)
attributedString.addAttributes(
[NSAttributedStringKey.paragraphStyle : paragraphStyle],
range: NSMakeRange(0, attributedString.length))
attributedString.addAttributes(
textAttributes,
range: NSMakeRange(0, attributedString.length))
let string:NSString = NSString(string: formattedString)
let rangeForBullet:NSRange = string.range(of: bullet)
attributedString.addAttributes(bulletAttributes, range: rangeForBullet)
bulletList.append(attributedString)
}
return bulletList
}
Вот результат:
