[Bridge] Support background restoration

[jacobrosenthal]

Right now when an app is launched, the launchoptions are given to a native module via the setBridge function. This is handy for push notifications as you can know what notification launched you, etc.

That paradigm doesnt work for Corelocation and Corebluetooth restoration though. These trigger a didFinishLaunchingWithOptions in order to tell the app that a location or device it was told to track has resurfaced. The rest of the app is never launched though, so setbridge never happens. Its common to do a push notification right there or restart your bluetooth stack to do some action. So I think we need a way to register functions to be called upon those launchoptions keys.

@jacobrosenthal I see we share common interests. :)

I think what you may be referring to might be a bit different than the referenced issue.
Are you maybe referring to ranging for beacons in the background?

I'm currently working on a library that will support both iBeacon and Eddystone beacons for react native that might help.

I'm interested in this for another reason, but not sure this is the right issue for this: Running JavaScript in response to remote background push notifications. I have some code implementing didReceiveRemoteNotification in AppDelegate.m that passes the notification on to RCTPushNotificationManager. However, the actual JavaScript event handler is only going to run as long as the app hasn't been suspended by iOS. I'm wondering whether there is a way to wake up the app shortly & handle the event, or to run a specific JavaScript module designed for handling the message, maybe storing data via AsyncStorage and presenting a local notification.

@ehd I think what you need is actually supported (I have it working). If your server sends a voip push notification (rather than a regular push notification with content-available=1) then iOS will launch your app.
