Q: Event on success of requestAlwaysAuthorization?

[arcbus]

It does take and call success/failure callbacks, but appears to fire success simply on the display of the prompt. Whereas I need a callback on accepting of the permission to always monitor beacons.

Problem i'm having is that on first launch of the app, i'm executing the startMonitoringForRegion before the permission has been accepted by user, and then i get:

"Monitor error: The operation couldn’t be completed. (kCLErrorDomain error 4.)"

Whereas i'd like to wait for user acceptance before starting the monitor.

Is there some other way to capture when user has granted monitoring permission?

Below is my code around requesting authorization. Seems no matter what, i always get onAuth (success callback) fired as soon as requestAlwaysAuthorization is called. Whether i allow or don't allow, and on subsequent launches when permission doesn't exist.

Would be helpful if it called failure/success according to users selection, and if it waited till the user made a selection. Just a suggestion.

var onNoAuth = function() {
    console.log('user didnt authorize, cant monitor beacons');
  };

  var onAuth = function() {
    console.log('user did authorize, start monitoring beacons');
    estimote.beacons.startMonitoringForRegion(
            {}, 
            app.onMonitor,
            app.onError);
  };

estimote.beacons.requestAlwaysAuthorization(
    onAuth,
    onNoAuth
);

Well, answered my own question. Hopefully it helps someone else.

The success call back from requestAlwaysAuthorization merely says the check for auth succeeded, not that auth was granted. It takes a result, which is an int to indicate state of authentication, so if we see it hasn't been granted yet, we just keep checking after a delay. This repeats until we know if granted or not.

var onAuth = function(result) {
                var msg = "";

                // result == null for not yet asked, i think 0 means it was declined
                if ( result == 0  || result == null){
                    msg = "Requesting permission";
                    setTimeout(function() {
                        // check again after delay
                        estimote.beacons.authorizationStatus(
                            onAuth,
                            onNoAuth
                        );
                    }, 2000);
                }

                // result == 2 for never authorized
                if ( result == 2 )
                    msg = "Enable Location services for maximum joy!";

                // result == 3 for always (assuming 1 means while app is running)
                if ( result == 3 || result == 1){
                    msg = "Looking for beacons!";

                    // Start monitoring.
                    estimote.beacons.startMonitoringForRegion(
                        {},
                        app.onMonitor,
                        app.onError);
                    }

                var element = $("<div>"+msg+"</div>");
                $('.fixedheader').append(element);  
            };

This confused the hell out of me too. Thanks for the post.

I am having an issue where startMonitoringForRegion will cause the app to crash if permission is not allowed, so will need to work around this using your solution.

Cheers,
