在120个字符后附加readmore标签，并使其在ios中可点击 [英] Append readmore label after 120 char, and make it clickable in ios

问题描述

数据来自解析器，如果文本超过120个字符，那么它应该像facebook一样追加... ReadMore。我有附加文本的代码，但不知道如何制作可点击链接。我正在使用Swift Languange。

The data is coming from parser, if the text is more than 120 char then it should append "...ReadMore" just like facebook. I have got the code for appending text, but dont know how to make clickable link. I'm using Swift Languange.

if cell!.bhikmangaTextlbl!.text!.utf16Count >= 120
    {
     var abc : String =  (cell!.bhikmangaTextlbl!.text! as 
    NSString).substringWithRange(NSRange(location: 0, length: 120))
     abc += " ...ReadMore"
      cell!.bhikmangaTextlbl!.text = abc

    }

推荐答案

@Mihir Mehta, This is code i have implemented.

    var bhikmangaTextlbl:UITextView?  
if cell!.bhikmangaTextlbl!.text!.utf16Count >= 120
            {
                var abc : String =  (cell!.bhikmangaTextlbl!.text! as NSString).substringWithRange(NSRange(location: 0, length: 120))
                    abc += "...ReadMore"
                    cell!.bhikmangaTextlbl!.text = abc
                var attribs = [NSForegroundColorAttributeName: UIColor.blackColor(), NSFontAttributeName: UIFont.systemFontOfSize(14.0)]
                var attributedString: NSMutableAttributedString = NSMutableAttributedString(string: abc, attributes: attribs)
                attributedString.addAttribute(NSLinkAttributeName, value: "...ReadMore", range: NSRange(location: 120, length: 11))
                attributedString.addAttribute(NSUnderlineStyleAttributeName, value: NSUnderlineStyle.StyleSingle.rawValue, range: NSRange(location: 120, length: 11))
                cell!.bhikmangaTextlbl!.attributedText = attributedString
            }


     //The function you said i have written here
        func textView(textView: UITextView, shouldInteractWithURL URL: NSURL, inRange characterRange: NSRange) -> Bool
            {
                return true
            }
