Why do you need this?

This repo is based on a solution found online but it doesnt handle two scenarios i.e number of lines and a tap action , it is totally dependent on the frame of the label.This repo handles both problems , adds a trailing text based on the number of lines you specify and also provides a delegate method to handle the tap.Moreover the solution used online involves a lot of down casting to NSString and using its funcs.This repo uses a pure swift apprach in most cases possible to solve the problem.

Usage:

Well the width of the label should be of the form (a^2+b^345) = y + 3 and height = z/(4/3)^6 for it to work :p Just kidding , all you have to do is add the label to your view heirarchy and then :

self.lblDescription.text = readMoreString
self.lblDescription.layoutIfNeeded()
self.lblDescription.addTrailingText(textToAppend: "Read More", fontOfTextToAppend: UIFont, colorOfTextToAppend: UIColor))

here lblDescription.layoutIfNeeded() is reqired to give the label the correct width before i begin the internal manipulation of strings followed by the font and color of the text required.

Note:

This concept uses a lot of apple's api's which are not widely used , research well before you modify.Simple to use but complex to understand and implement.
