iOS device orientation disregarding orientation lock

Question

I want to query the orientation the iPhone is currently in. Using

[UIDevice currentDevice].orientation

works as long as the device isn\'t

Answer 1

Using Satachito's great answer here is code which will also detect if the device is face up or face down

import CoreMotion

---

var mm: CMMotionManager!

init() {
    self.mm = CMMotionManager()
    self.mm.accelerometerUpdateInterval = 0.2
}

public func startOrientationUpdates() {
    //  Using main queue is not recommended. So create new operation queue and pass it to startAccelerometerUpdatesToQueue.
    //  Dispatch U/I code to main thread using dispach_async in the handler.
    self.mm.startAccelerometerUpdates( to: OperationQueue() ) { p, _ in
        if let p = p {
            if(p.acceleration.x > -0.3 && p.acceleration.x < 0.3 && p.acceleration.z < -0.95) {
                print("face up")
            }
            else if(p.acceleration.x > -0.3 && p.acceleration.x < 0.3 && p.acceleration.z > 0.95) {
                print("face down")
            }
            else {
                print(
                    abs( p.acceleration.y ) < abs( p.acceleration.x )
                        ?   p.acceleration.x > 0 ? "Right"  :   "Left"
                        :   p.acceleration.y > 0 ? "Down"   :   "Up"
                )
            }

        }
    }
}

public func endOrientationUpdates() {
    self.mm.stopAccelerometerUpdates()
}
