WhatsApp share not working properly while "&" is contain in link

Sample Code:

let sampleURL = "http://Hello/site/link?id=MTk=&fid=MTA="
let urlWhats = "whatsapp://send?text=\(sampleURL)"
if let urlString = urlWhats.addingPercentEncoding(withAllowedCharacters: .urlQueryAllowed) {
   if let whatsappURL = NSURL(string: urlString) {
      if UIApplication.shared.canOpenURL(whatsappURL as URL) {
           UIApplication.shared.open(whatsappURL as URL)
      }
      else {
           // Open App Store.
      }
   }
}

added in .plist file

<key>LSApplicationQueriesSchemes</key>
<array>
    <string>whatsapp</string>
</array>

Facing issue is while sharing link with & text not coming after &

For above url text is coming like http://Hello/site/link?id=MTk=

Thanks in advance

Solution

  • Different parts of an URL have different encoding rules. addingPercentEncoding is very tricky to use correctly. As a rule, you should not try to encode your own URLs. Let the system do it for you with URLComponents:

    //For the constant part of the link, it's fine to just use a string
var sample = URLComponents(string: "whatsapp://send")!

// Then add a query item
sample.queryItems = [URLQueryItem(name: "text", value: "http://Hello/site/link?id=MTk=&fid=MTA=")]

// Extract the URL, which will have the correct encoding
print(sample.url!)
// whatsapp://send?text=http://Hello/site/link?id%3DMTk%3D%26fid%3DMTA%3D
