Append readmore label after 120 char, and make it clickable in ios

Question

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

    }

Answer 1

@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
            }

You can use attributed string here ... and make some part of text clickable

here is Objective C code. You can write same for Swift

NSDictionary *attribs = @{
                              NSForegroundColorAttributeName: BODY_FONT_COLOR,
                              NSFontAttributeName: [UIFont fontWithName:FontHelvetica size:AppFont16]
                              };
    NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc] initWithString:ACCIDENT_DETECTION_AUTOMATIC_TEXT attributes:attribs];
    [attributedString addAttribute:NSLinkAttributeName
                             value:@"Accident detection"
                             range:[[attributedString string] rangeOfString:@"Read More"]];




    NSDictionary *linkAttributes = @{NSForegroundColorAttributeName: LINKS_FONT_COLOR,
                                     NSUnderlineColorAttributeName: [UIColor clearColor],
                                     NSUnderlineStyleAttributeName: @(NSUnderlineStyleNone)};

    // assume that textView is a UITextView previously created (either by code or Interface Builder)
    self.accidentDetectionText.linkTextAttributes = linkAttributes; // customizes the appearance of links
    self.accidentDetectionText.attributedText = attributedString;
