    let escapedString = originalString.addingPercentEncoding(withAllowedCharacters:CharacterSet.urlQueryAllowed)

    let url  = URL(String: "whatsapp://send?text=\(escapedString!)")

    if UIApplication.shared.canOpenURL(url! as URL)
    {
        UIApplication.shared.open(url! as URL,options: [:],completionHandler: nil)
    }
}

@IBACtion func whatsappShareLink(_ sender: AnyObject)

    let escapedString = originalString.addingPercentEncoding(withAllowedCharacters:CharacterSet.urlQueryAllowed)
    let url  = URL(String: "whatsapp://send?text=\(escapedString!)")

    if UIApplication.shared.canOpenURL(url! as URL)
