Carplay connect/disconnect events?

Question

Is there a way to detect in an app if the phone was connected/disconnected to/from the car using Carplay? Can't seem to find any documentation regarding it. I'm thinking of some system event like that I could monitor.

Answer 1

Have you followed these steps?

1. Add corresponding record to your project's Entitlements file: com.apple.developer.carplay-maps type of Boolean with value YES
2. Request from Apple corresponding permission
3. Make your AppDelegate confirm to CPApplicationDelegate protocol

4. Implement the next methods:

   /**
    The CarPlay screen has connected and is ready to present content.
   
    Your app should create its view controller and assign it to the @c rootViewController property
    of this window.
   
    @note It is the responsibility of the delegate to maintain a reference to the interface controller beyond the scope of this method.
    */
   - (void)application:(UIApplication *)application didConnectCarInterfaceController:(CPInterfaceController *)interfaceController toWindow:(CPWindow *)window;
    /**
    The CarPlay screen has disconnected.
     */
   - (void)application:(UIApplication *)application didDisconnectCarInterfaceController:(CPInterfaceController *)interfaceController fromWindow:(CPWindow *)window;
