如何从一侧弯曲或扭曲UILabel文本

// 创建UILabel并设置frame和文本内容
let label = UILabel(frame: CGRect(x: 0, y: 0, width: 200, height: 100))
label.text = "Hello World"

// 使用NSAttributedString设置文本属性
let attributedText = NSMutableAttributedString(string: label.text!)
let attributes: [NSAttributedString.Key: Any] = [
    .font: UIFont.systemFont(ofSize: 20),
    .foregroundColor: UIColor.black,
    .kern: 2 // 字符间距
]
attributedText.addAttributes(attributes, range: NSRange(location: 0, length: attributedText.length))
label.attributedText = attributedText

// 创建UIBezierPath对象并定义文本形状
let path = UIBezierPath()
path.move(to: CGPoint(x: 0, y: label.bounds.height / 2))
path.addCurve(to: CGPoint(x: label.bounds.width, y: label.bounds.height / 2),
              controlPoint1: CGPoint(x: label.bounds.width / 4, y: 0),
              controlPoint2: CGPoint(x: label.bounds.width * 3 / 4, y: label.bounds.height))

// 应用UIBezierPath对象到UILabel的layer的mask属性上
let shapeLayer = CAShapeLayer()
shapeLayer.path = path.cgPath
label.layer.mask = shapeLayer
