The SCiO device class enables the application to register a few callback functions, to receive notifications for various events:

• setDeviceButtonBlock()

Pressing on the SCiO device’s button triggers the setDeviceButtonBlock event. The application can register an event handler for a button press and initiate actions upon it, for example, to scan a sample.

- (void)viewDidLoad {
     [super viewDidLoad];
     _models = [NSArray array];
     [[CPScioDevice sharedInstance] setDeviceButtonBlock:^{
     // Enter code for handling the button press event here
     }];
  }
