Question

When my project running the face recognition module continues to output:

There is no server connection for kCTConnectionInvalidatedNotification.

What could be causing the problem? how can i solve this?

Answer 1

If you used some kind of socket connection, you need to pay attention:

1. Periodically send a server bit to the server.
2. When the client loses the client, you need to connect to the server (if you do not want this).
