Get Siri Remote orientation (or get notifications of change?)

Question

I'm been searching for a way to check the Siri Remote's current orientation or to register for Siri Remote orientation changes, but I haven't found anything yet. Is it possible to do this (without resorting to interpreting the raw gravity data)?

I've have found out how to disable auto-orientation changes with "allowsRotation" on "microGamepad". Which is pretty cool!

Answer 1

I didn't see an API either, however as you mentioned, you can poll for the gravity data, and I just wanted to post that code here in case some find it useful. You can modify this to your own need, such as detecting last orientation and comparing it to current if you want a callback of the change.

    @property (strong) CADisplayLink *updateLoopTimer;
    self.updateLoopTimer = [CADisplayLink displayLinkWithTarget:self selector:@selector(updateRefreshRate:)];
    [self.updateLoopTimer addToRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode];
    -(void)updateRefreshRate:(CADisplayLink *)displayLink
    {
        CFTimeInterval deltaTime = displayLink.duration * displayLink.frameInterval;
        [self update:(float)deltaTime];
    }

    if( self.gameController != nil )
    {
        GCMicroGamepad* microPad = self.gameController.microGamepad;
        if ( microPad != nil )
        {
            GCMotion *motion = self.gameController.motion;
            GCControllerDirectionPad *dpad = microPad.dpad;

            if( motion != nil )
            {
                GCAcceleration accelVector = motion.gravity;
                if( fabs(accelVector.x) > fabs(accelVector.y) )
                {
                    NSLog(@"Sideways");
                }
                else
                {
                    NSLog(@"Upright");
                }

            }
        }
