Problems sending to APNS

[joanlopez]

My code is failing on the line:

Yii::$app->apns

The problem is with the APNS config, because I've tried to create a component called 'apns' with the GCM configuration and it works.

I've copied the APNS configuration from the example of the README, but it is not working.

How I can find which is the problem?
I've tried to declare the component only with the 'class', but it still not working.

I'm not having any PHP error, but the server returns a 500 error when executes this line.

Thanks!
