Inheritance diagram for GDReachability:

Description

This class represents the status of the connection from the application to the BlackBerry Dynamics infrastructure.

Every BlackBerry Dynamics application connects to the BlackBerry Dynamics infrastructure whenever possible. The connection is maintained by the BlackBerry Dynamics runtime instance that is embedded in the application. The infrastructure includes the BlackBerry Dynamics Network Operation Center (NOC) as well as a number of other components that can be installed by the enterprise.

The current status can be obtained synchronously. It is also possible to receive notifications whenever the status changes. Use the native NSNotificationCenter programming interface, with the following parameters.

• Set the notification name to the GDReachabilityChangedNotification value.
• Set the notification object to the BlackBerry Dynamics runtime interface object, obtained by [GDiOS sharedInstance].

Code Snippets

The following code snippets illustrate some common tasks.

Register for notification

- (void)addChangeConnectionStatusObserver {
 [[NSNotificationCenter defaultCenter] addObserver:self
                                          selector:@selector(reachabilityChanged:)
                                              name:GDReachabilityChangedNotification
                                            object:[GDiOS sharedInstance]];
}

- (void)reachabilityChanged:(NSNotification *)notification {
 GDReachability *reachability = [GDReachability sharedInstance];
 
 if (reachability.status == GDReachabilityNotReachable) {
 
     UIAlertView* alert = [[UIAlertView alloc] initWithTitle:@"Error"
                                                     message:@"Network NOT Available"
                                                    delegate:nil
                                           cancelButtonTitle:@"OK"
                                           otherButtonTitles:nil, nil];
     [alert show];
 
 } else {
 
     UIAlertView* alert = [[UIAlertView alloc] initWithTitle:@"Success"
                                                     message:@"Network Available"
                                                    delegate:nil
                                           cancelButtonTitle:@"OK"
                                           otherButtonTitles:nil, nil];
     [alert show];
 
 }

The above snippet shows:

• Registration for notification of changes in connection status. The observer code is specified by a selector.
• Implementation of the selector, which displays a message to the user.

Method Documentation

sharedInstance

+ (instancetype) sharedInstance

This function returns a reference to the BlackBerry Dynamics infrastructure connection status object, which is a "singleton class".

Returns

Reference that can be used, for example, to access the status property.

isNetworkAvailable

+ (BOOL) isNetworkAvailable

Deprecated:

This function is deprecated and will be removed in a future release. Use the isNetworkAvailable property instead.

Returns

YES if there is a current connection to the infrastructure.

NO otherwise.

Property Documentation

status

- (GDReachabilityStatus) status

readnonatomicassign

The value of this property represents the type of connection through which the BlackBerry Dynamics infrastructure is reachable. It always takes a value from the GDReachabilityStatus enumeration:

• GDReachabilityViaCellular if the infrastructure is reachable via a mobile data (cellular) connection.
• GDReachabilityViaWiFi if the infrastructure is reachable via a Wi-Fi connection.
• GDReachabilityNotReachable if the infrastructure isn't reachable.

isNetworkAvailable

- (BOOL) isNetworkAvailable

readnonatomicassign

The value of this property represents the availability of the connection to the BlackBerry Dynamics infrastructure.

A change to the availability of the connection will trigger an infrastructure status change notification to the application. See the class description, above, for details of how to register for these notifications. In addition, key-value observing (KVO) can be applied to this property.

isPushChannelAvailable

- (BOOL) isPushChannelAvailable

readnonatomicassign

The value of this property represents the availability of the BlackBerry Dynamics Push Channel service. For an overall description of how to use the service, see under GDPushChannel .

A change to the availability of the Push Channel service will trigger an infrastructure status change notification to the application. See the class description, above, for details of how to register for these notifications. In addition, key-value observing (KVO) can be applied to this property.
