Can push notification be sent without an alert for certain actions?
<p>I know you can register to have alerts or not when you call the push notification API. However my problem is that I want a certain class of actions to have an alert notification while no alert notification for other class of action? </p>

<p>So for example, an alert should be shown when we send the notification "Heart rate dropping alert!". But no alert should be shown when we send the notification "downloading updated patient data", the app should just take the notification as an instruction to being download if it is launched. And simply ignore it if it is not launched.</p>

<p>How to implement this?</p>
