How to take CMDeviceMotion updates in multiple handlers?

Question

Apple says: You should only create a single instance of CMMotionManager to get accurate data.

What if I want to start the device motion updates when the app starts and then take the updatesToQueue at multiple places.

Scenario is something like this:

App starts - Start device motion updates without handler

ClassA - Start device motion updates to queue at a particular time.

ClassB - Start device motion updates to queue at a particular time.

Stop device motion updates when required.

What about using a Singleton class? – Larme Aug 14 '15 at 08:01 — Larme, Aug 14 '15 at 08:01

Start CMMotionManager with a handler that posts notifications (see NSNotificationCenter). Your other classes can then listen for that notification when needed.
