    <p>It is best to manage your connection to Sphero and open/close it in one place. I find it is easiest to do this in the AppDelegate or the RootViewController.</p> <p>For AppDelegate:</p> <ul> <li>Open connection on applicationDidBecomeActive and applicationWillEnterForeground</li> <li>Close connection on applicationWillResignActive and applicationWillTerminate</li> <li>Register for robot state notifications in application didFinishLaunchingWithOptions</li> </ul> <p>If you want to manage the connection in your RootViewController, register for robot notifications on load as well as the same application state notifications mentioned above and do the same connection handling.</p> <p>By connecting in your AppDelegate/RootViewController you can allow your other ViewControllers to not care about handling the connection. You can either have them assume a Sphero is connected if you have logic to notify the user in AppDelegate/RootViewController, or you can share the state.</p> <p>As for the particular use cases you mentioned I would recommend the following: 1. Add the data streaming and response observer on viewDidLoad, you should also enable data streaming here. Remove the observers on viewDidUnload and disable data streaming. 2. Use the multiplayer classes here as you normally would. 3. Add the data streaming and response observer on viewDidLoad, you should also enable data streaming here. Remove the observers on viewDidUnload and disable data streaming. Send joystick roll commands normally.</p> <p>If you would like information about the robot connection state changing you can register/unregister for the connection notifications in each views viewDidLoad/viewDidUnload calls.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
