Cordova PushNotification Plugin

by Olivier Louvignes

DESCRIPTION

• This plugin provides a simple way to use Apple Push Notifications (or Remote Notifications) from IOS. It does comply with the latest (future-2.x) cordova standards.

• This was inspired by the now orphaned ios-phonegap-plugin build by Urban Airship.

PLUGIN SETUP

Using this plugin requires Cordova iOS.

1. Make sure your Xcode project has been updated for Cordova

2. Drag and drop the PushNotification folder from Finder to your Plugins folder in XCode, using "Create groups for any added folders"

3. Add the .js files to your www folder on disk, and add reference(s) to the .js files using <script> tags in your html file(s)

   <script type="text/javascript" src="/js/plugins/PushNotification.js"></script>

4. Add new entry with key PushNotification and value PushNotification to Plugins in Cordova.plist/Cordova.plist

APPDELEGATE SETUP

This plugin requires modifications to your AppDelegate.m. Append the block below at the end of your file, between your dealloc method and the implementation @end.

/* ... */

- (void) dealloc
{
    [super dealloc];
}

/* START BLOCK */

#pragma PushNotification delegation

- (void)application:(UIApplication*)app didRegisterForRemoteNotificationsWithDeviceToken:(NSData*)deviceToken
{
    PushNotification* pushHandler = [self.viewController getCommandInstance:@"PushNotification"];
    [pushHandler didRegisterForRemoteNotificationsWithDeviceToken:deviceToken];
}

- (void)application:(UIApplication*)app didFailToRegisterForRemoteNotificationsWithError:(NSError*)error
{
    PushNotification* pushHandler = [self.viewController getCommandInstance:@"PushNotification"];
    [pushHandler didFailToRegisterForRemoteNotificationsWithError:error];
}

- (void)application:(UIApplication*)application didReceiveRemoteNotification:(NSDictionary*)userInfo
{
    PushNotification* pushHandler = [self.viewController getCommandInstance:@"PushNotification"];
    NSMutableDictionary* mutableUserInfo = [userInfo mutableCopy];

    // Get application state for iOS4.x+ devices, otherwise assume active
    UIApplicationState appState = UIApplicationStateActive;
    if ([application respondsToSelector:@selector(applicationState)]) {
        appState = application.applicationState;
    }

    [mutableUserInfo setValue:@"0" forKey:@"applicationLaunchNotification"];
    if (appState == UIApplicationStateActive) {
        [mutableUserInfo setValue:@"1" forKey:@"applicationStateActive"];
        [pushHandler didReceiveRemoteNotification:mutableUserInfo];
    } else {
        [mutableUserInfo setValue:@"0" forKey:@"applicationStateActive"];
        [mutableUserInfo setValue:[NSNumber numberWithDouble: [[NSDate date] timeIntervalSince1970]] forKey:@"timestamp"];
        [pushHandler.pendingNotifications addObject:mutableUserInfo];
    }
}

/* STOP BLOCK */

@end

In order to support launch notifications (app starting from a remote notification), you have to add the following block inside - (BOOL) application:(UIApplication*)application didFinishLaunchingWithOptions:(NSDictionary*)launchOptions, just before the return YES;

[self.window addSubview:self.viewController.view];
[self.window makeKeyAndVisible];

/* START BLOCK */

// PushNotification - Handle launch from a push notification
NSDictionary* userInfo = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
if(userInfo) {
    PushNotification *pushHandler = [self.viewController getCommandInstance:@"PushNotification"];
    NSMutableDictionary* mutableUserInfo = [userInfo mutableCopy];
    [mutableUserInfo setValue:@"1" forKey:@"applicationLaunchNotification"];
    [mutableUserInfo setValue:@"0" forKey:@"applicationStateActive"];
    [pushHandler.pendingNotifications addObject:mutableUserInfo];
}

/* STOP BLOCK */

return YES;

JAVASCRIPT INTERFACE

// After device ready, create a local alias
var pushNotification = window.plugins.pushNotification;

registerDevice() does perform registration on Apple Push Notification servers (via user interaction) & retrieve the token that will be used to push remote notifications to this device.

pushNotification.registerDevice({alert:true, badge:true, sound:true}, function(status) {
    // if successful status is an object that looks like this: 
    // {"type":"7","pushBadge":"1","pushSound":"1","enabled":"1","deviceToken":"blablahblah","pushAlert":"1"}
    console.warn('registerDevice:%o', status);
    navigator.notification.alert(JSON.stringify(['registerDevice', status]));
});

getPendingNotifications() should be used when your application starts or become active (from the background) to retrieve notifications that have been pushed while the application was inactive or offline. For now, it can only retrieve the notification that the user has interacted with while entering the app. Returned params applicationStateActive & applicationLaunchNotification enables you to filter notifications by type.

pushNotification.getPendingNotifications(function(notifications) {
    console.warn('getPendingNotifications:%o', notifications);
    navigator.notification.alert(JSON.stringify(['getPendingNotifications', notifications]));
});

getRemoteNotificationStatus() does perform registration check for this device.

pushNotification.getRemoteNotificationStatus(function(status) {
    console.warn('getRemoteNotificationStatus:%o', status);
    navigator.notification.alert(JSON.stringify(['getRemoteNotificationStatus', status]));
});

setApplicationIconBadgeNumber() can be used to set the application badge number (that can be updated by a remote push, for instance, resetting it to 0 after notifications have been processed).

pushNotification.setApplicationIconBadgeNumber(12, function(status) {
    console.warn('setApplicationIconBadgeNumber:%o', status);
    navigator.notification.alert(JSON.stringify(['setBadge', status]));
});

cancelAllLocalNotifications() can be used to clear all notifications from the notification center.

pushNotification.cancelAllLocalNotifications(function() {
    console.warn('cancelAllLocalNotifications');
    navigator.notification.alert(JSON.stringify(['cancelAllLocalNotifications']));
});

getDeviceUniqueIdentifier() can be used to retrieve the original device unique id. (@warning As of today, usage is deprecated and requires explicit consent from the user)

pushNotification.getDeviceUniqueIdentifier(function(uuid) {
    console.warn('getDeviceUniqueIdentifier:%s', uuid);
    navigator.notification.alert(JSON.stringify(['getDeviceUniqueIdentifier', uuid]));
});

Finally, when a remote push notification is received while the application is active, an event will be triggered on the DOM document.

document.addEventListener('push-notification', function(event) {
    console.warn('push-notification!:%o', event);
    navigator.notification.alert(JSON.stringify(['push-notification!', event]));
});

Patches welcome! Send a pull request. Since this is not a part of Cordova Core (which requires a CLA), this should be easier.
