title: "CBCentralManager(delegate: self, queue: nil)" does not show Bluetooth popup message when Bluetooth is turned off from Control Center
body: <p>I am trying to navigate the user to <strong>Bluetooth settings</strong> on a button click. <code>CBCentralManager(delegate: self, queue: nil)</code> works fine when Bluetooth is turned off from Settings App, <strong>but it is not working when Bluetooth is turned off from Control center e.g not showing the default Bluetooth popup</strong>.<br>
  Now I need to know if Bluetooth is turned off from the Control center so that I can show some custom popup message to the user. </p>
  
  <p>Any help will be appreciated. </p>
