如何对齐文本或使其停止在UITextview中分隔单词？

let paragraphStyle = NSMutableParagraphStyle()
paragraphStyle.alignment = .center

let attributedString = NSAttributedString(string: "Your text", attributes: [NSAttributedString.Key.paragraphStyle: paragraphStyle])
textView.attributedText = attributedString

let textContainer = NSTextContainer(size: textView.bounds.size)
textContainer.lineBreakMode = .byWordWrapping

textView.layoutManager.addTextContainer(textContainer)

let attributedString = NSAttributedString(string: "Your text")
let framesetter = CTFramesetterCreateWithAttributedString(attributedString)

let path = CGPath(rect: textView.bounds, transform: nil)
let frame = CTFramesetterCreateFrame(framesetter, CFRangeMake(0, attributedString.length), path, nil)

let context = UIGraphicsGetCurrentContext()
CTFrameDraw(frame, context!)
