title: Adding Click Event on InfoWindow/Marker in Google Maps SDK for native iOS/objective C
body: <p>Simple Question</p>
  
  <p>I´m working on an App for iOS where I embedded the new Google Map for native iOS.
  Everything works fine except one problem where I can´t find a propper solution for native IOS/ Objective-C  neither here nor at google (if there is one please show me and sorry for annoying you)</p>
  
  <p>What I want:
  I want the User to Click on the Marker that opens the Info Window. After If he clicks or taps on the Info Window it should open a New UIView with further Informations.</p>
  
  <p>How can I do that?</p>
  
  <p>Thanks for advices</p>
