  5. Add the event-handler skeleton manually

Add the event-handler skeleton manually

The application-delegate object
UIApplicationDelegate
 manages the
iOS
 app life cycle using events. You can decide how to implement the life cycle of events; the steps below provide an example that is based loosely on the
Apple
 Breadcrumbs sample app (with differences in declarations and other key areas). Several of the sample apps included in the SDK also demonstrate the event handling lifecycle.
  1. Specify the entitlement ID (
    GDApplicationID
    ) and entitlement version (
    GDApplicationVersion
    ) in the
    Info.plist
     file. See Using an entitlement ID and version to uniquely identify a BlackBerry Dynamics app.
  2. Import
    GDiOS.h
     and implement a skeleton
    GDiOSDelegate
     protocol. The example here relies on a boolean variable named
    started
    . An alternative approach is to declare the variable in your project's
    .m
     file.
    // AppDelegate.h
    #import <UIKit/UIKit.h>
    #import <GD/GDiOS.h>
    
    @interface AppDelegate : UIResponder <UIApplicationDelegate, GDiOSDelegate> {
        BOOL started;
    }
    
    @property (strong, nonatomic) UIWindow *window;
    @property (strong, nonatomic) GDiOS *good;
    
    - (void)onAuthorized:(GDAppEvent *)anEvent;
    - (void)onNotAuthorized:(GDAppEvent *)anEvent;
    
    @end
  3. Build the app and verify that there are no warnings or errors.
  4. Use
    GDAppEvent
     to process events. Move the application launch code from
    didFinishLaunchingWithOptions
     to the
    GDAppEvent
     handler method.
    // AppDelegate.m
    - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
        // Override point for customization after application launch.
        self.good = [GDiOS sharedInstance];
        _good.delegate = self;
        started = NO;
        //Show the BlackBerry Authentication UI.
        [_good authorize];
        
        return YES;
    }
    
    #pragma mark BlackBerry Dynamics Delegate Method
    - (void)handleEvent:(GDAppEvent *)anEvent
    {
        /* Called from _good when events occur, such as system startup. */
        switch (anEvent.type)
        {
            case GDAppEventAuthorized:
            {
                [self onAuthorized:anEvent];
                break;
            }
            case GDAppEventNotAuthorized:
            {
                [self onNotAuthorized:anEvent];
                break;
            }
            case GDAppEventRemoteSettingsUpdate:
            {
                // handle app config changes
                break;
            }
            case GDAppEventPolicyUpdate:
            {
                // handle app policy changes
                break;
            }
            case GDAppEventServicesUpdate:
            {
                // handle services changes
                break;
            }
            case GDAppEventEntitlementsUpdate:
            {
                // handle entitlements changes
                break ;
            }
            default:
                NSLog(@"Unhandled Event");
                break;
        }
    }
  5. Special-case the
    onNotAuthorized
     events. Verify that the app can handle authorization errors or functionality like remote wipe, a lockout, or blocking events. Implement these events in the
    onNotAuthorized
     function.
    - (void)onNotAuthorized:(GDAppEvent *)anEvent
    {
        /* Handle the BlackBerry Libraries not authorized event. */
        switch (anEvent.code) {
            case GDErrorActivationFailed:
            case GDErrorProvisioningFailed:
            case GDErrorPushConnectionTimeout:
            case GDErrorSecurityError:
            case GDErrorAppDenied:
            case GDErrorBlocked:
            case GDErrorWiped:
            case GDErrorRemoteLockout:
            case GDErrorPasswordChangeRequired: {
                // A condition has occurred denying authorization, an application may wish to log these events
                NSLog(@"onNotAuthorized %@", anEvent.message);
                break;
            }
            case GDErrorIdleLockout: {
                // idle lockout is benign & informational
                break;
            }
            default:
                NSAssert(false, @"Unhandled not authorized event");
                break;
        }
    }
  6. On authorization, start the app. Initialize and start the UI with the
    onAuthorized
     function. The
    GDErrorNone
     event is returned by the
    BlackBerry Dynamics Runtime
     whenever a container is opened and no error occurs.
    - (void)onAuthorized:(GDAppEvent *)anEvent
    {
        /* Handle the BlackBerry Libraries authorized event. */
        switch (anEvent.code) {
            case GDErrorNone: {
                // started was declared in first step.
                if (!started) {
                    // launch application UI here
                    started = YES;
                }
                break;
            } default:
                NSAssert(false, @"Authorized startup with an error");
                break;
        }
    }
  8. Add
    GDAssets.bundle
     to the
    Copy Bundle Resources
     build phase in
    Xcode
    . Verify that the copy of the bundle that is distributed with the framework has been added to the project.
