问题
I'm developing an ios sender and custom-receiver app with the Google-Cast-SDK v3.
I can't seem to find the appropriate method to send a message containing a JSON to the Receiver-App. Do I have to use the sendTextMessage-function or is there a better way?
Would this "new" function be able to send a base64 coded image? (The Backend has no real file-management yet and this is all I can work with right now.)
Thanks for your answers
回答1:
Yes, you'll want to create a GCKCastChannel instance (for your namespace), and use sendTextMessage, that is the correct way.
You could also push a base64 string via the same method.
