FAQ:

1. How to register notification? (Client Side)

In AppDelegate file, add methods below to register device token

- (void)application:(UIApplication*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData*)deviceToken
{
    NSString * tokenAsString = [[[deviceToken description] 
                                 stringByTrimmingCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@"<>"]] 
                                stringByReplacingOccurrencesOfString:@" " withString:@""];    
    NSString *urlAsString = [NSString stringWithFormat:@"http://serverIP:4567/v1/apps/app1/%@", token];
    NSURL *url = [NSURL URLWithString:urlAsString];
    NSMutableURLRequest *urlRequest = [NSMutableURLRequest requestWithURL:url]; 
    [urlRequest setTimeoutInterval:30.0f];
    [urlRequest setHTTPMethod:@"GET"];
    NSOperationQueue *queue = [[[NSOperationQueue alloc] init] autorelease];
    [NSURLConnection sendAsynchronousRequest:urlRequest queue:queue completionHandler:nil]; 
}

- (void)application:(UIApplication*)application didFailToRegisterForRemoteNotificationsWithError:(NSError*)error
{
    NSLog(@"Failed to get token, error: %@", error);
}
