Swift wkwebview message handler

WKScriptMessageHandler in swift

 

Today, we'll talk about WKScriptMessageHandler. The way of communicate with javascript.

 

Sometimes we want to get message from javascript.

You can catch user event so that handle event properly for example close webView.

You can do this by add userContentController to webView.

First. Add content controller to webView

 

Second, implement WKScriptMessageHandler

 

Note message.name should be same contentController’s name. message.body can be any type like string or json.

On javascript code, call postmessage to send message

 

Finally, Test with this function.

Happy coding :)
