ngCordova localnotification not working in ios devices?

I am getting following error

Local notification is working in Android , but getting the following error in ios ,

2016-12-02 17:58:30.430 TaskBean[450:60493] THREAD WARNING: [‘LocalNotification’] took ‘44.307129’ ms. Plugin should use a background thread.

Thanks in advance

This error, by it self, does not justify a ‘not working’ behavior. There is anything else on the XCode console?

I’ve used this plugin before and it works just fine in my case.

here i have attached the screen shot

This logs you posted here are happening everytime? It does not seems to present the behavior of your original question (the THREAD WARNING of plugin taking too long to respond is not there and you have a terminating exception that suggest your app not starts at all and is not related to the local Notification Plugin).

Then what about the local notification still it was not triggered … then what is the problem is there any solution … , How can you say " It does not seems to present the behavior of your original question " ??
