xcode swift如何在图像周围换行

import UIKit

func wrapTextAroundImage(image: UIImage, text: String, font: UIFont, imageSize: CGSize) -> NSAttributedString {
    let textAttachment = NSTextAttachment()
    textAttachment.image = image
    textAttachment.bounds = CGRect(origin: .zero, size: imageSize)
    
    let attributedString = NSMutableAttributedString(string: "")
    let imageString = NSAttributedString(attachment: textAttachment)
    attributedString.append(imageString)
    
    let textString = NSAttributedString(string: text, attributes: [NSAttributedString.Key.font: font])
    attributedString.append(textString)
    
    return attributedString
}

let image = UIImage(named: "image.jpg")!
let text = "这是一段文本，将围绕在图像周围换行显示。"
let font = UIFont.systemFont(ofSize: 16)
let imageSize = CGSize(width: 100, height: 100)

let wrappedText = wrapTextAroundImage(image: image, text: text, font: font, imageSize: imageSize)

let label = UILabel()
label.attributedText = wrappedText
label.numberOfLines = 0
label.sizeToFit()
