 UILocalNotification *notification = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
if (notification) {
    NSLog(@"app recieved notification from remote%@",notification);
    [self application:application didReceiveRemoteNotification:(NSDictionary*)notification];
}else{

When you receive remote notifications, -application:didReceiveRemoteNotification: is only called when your app is in the foreground. If your app is in the background or terminated, then the OS may display an alert or play a sound (depending on the aps dictionary in the notification), but the delegate method is not called.

The remote notification received in the background will only passed to your application if it is launched with that notification's action button, and then you need to look at the launch options dictionary on -application:didFinishLaunchingWithOptions: to see the content of the notification.

If you're looking at new content fetching/remote notification background support with iOS7, check Will iOS launch my app into the background if it was force-quit by the user? and see if that helps, as there are very specific circumstances that those functions work in.
