title: Global access to view properties
body: <p>A containerView1 with 3 buttons which will need their text changed and their visibility modified according to user interaction with views in  a different containerView2.<br>
  Each containerView has its viewController and there is the main viewController for the main storyBoard. The buttons will need to be Outlets as well as Actions.  </p>
  
  <p>Since the buttons are in a container whose controller is embedded segue, no prepareForSegue is allowed since there is no "segueing" here since the embed type is called during setup only.  </p>
  
  <p>What mechanise is best fit to be able to access the properties of the buttons from anywhere and how to implement it?</p>
  
  <p>thanks</p>
