An example of using the CarPlay framework in iOS 12 and later.
This sample project uses the CarPlay framework to start a simple navigation session
from your existing project. It utilizes the CPApplicationDelegate to connect to your
car, CPInterfaceController to attach your view controller and CPMapTemplate to show
and example template as part of the "root template" of the controller.
Some general hints I have noticed so far:
- CarPlay works primarily in "templates", not "views" or "controllers". It means that you cannot design your CarPlay screen like you would design your iOS app, but you need to provide information that is then displayed in the related template.
- The connection is done via the
CPApplicationDelegatedelegate that inherits from theUIApplicationDelegate, so you usually handle it as part of your main app-delegate class. - Once connected, you can push and pop templates like you would do with view controllers
- Data can be used by shared frameworks, networking or general persistence layer. In this
example, I simply persist an encoded dictionary of latitude and longitude pairs in the
UserDefaultsand grab it for my CarPlay connection once ready.
Let me know if you have further questions! As of for now, this is a tiny example to get your head around the whole framework, but it can be extended to show other template types like lists, grids and UI elements like alerts and notifications.
