如何添加“阅读更多”在Swift的Uilabel的第三行结束时

发布于 2025-01-30 18:36:44 字数 1321 浏览 4 评论 0原文

我需要在标签第三行的末尾添加更多。

这样我需要：

/添加读取的uilabel“> add” ...在uilabel的末尾读取更多“ ...因此，我需要像下面的尝试一样尝试

。在此处，如果说明更多，则我需要在第三行的结尾显示剩下的文本..

如果超过3行，我可以扩展标签

override func viewDidLoad() {
    super.viewDidLoad()

 despLbl.text = publicProGenInfo?.result?.user?.description
        despLbl.numberOfLines = 3//despLbl.maxNumberOfLines//3
        let tap:UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(self.labelAction(gesture:)))
        despLbl.addGestureRecognizer(tap)
        despLbl.isUserInteractionEnabled = true
        tap.delegate = self

   }

 @objc func labelAction(gesture: UITapGestureRecognizer)
  {
      if despLbl.numberOfLines == 3 {
          despLbl.numberOfLines = despLbl.maxNumberOfLines
      } else {
          despLbl.numberOfLines = 3
      }
  }

readmoretextview 是一个很好的选择，有几行代码，您可以实现此行为。

@IBOutlet weak var aboutMessageTextView: ReadMoreTextView!
aboutMessageTextView.text = "your text"
let readMoreTextAttributes: [NSAttributedString.Key: Any] = [
     NSAttributedString.Key.foregroundColor: UIColor.systemBlue,
     NSAttributedString.Key.font: UIFont.boldSystemFont(ofSize: 14)
   ]
aboutMessageTextView.attributedReadMoreText = NSAttributedString(string: " ... Read more", attributes: readMoreTextAttributes)
aboutMessageTextView.maximumNumberOfLines = 3
aboutMessageTextView.shouldTrim = true

ReadMoreTextView is a good option for this purpose, with a few lines of code you can achieve this behavior.

@IBOutlet weak var aboutMessageTextView: ReadMoreTextView!
aboutMessageTextView.text = "your text"
let readMoreTextAttributes: [NSAttributedString.Key: Any] = [
     NSAttributedString.Key.foregroundColor: UIColor.systemBlue,
     NSAttributedString.Key.font: UIFont.boldSystemFont(ofSize: 14)
   ]
aboutMessageTextView.attributedReadMoreText = NSAttributedString(string: " ... Read more", attributes: readMoreTextAttributes)
aboutMessageTextView.maximumNumberOfLines = 3
aboutMessageTextView.shouldTrim = true
