title: UiView Transition inside UIView
body: <p>this feels like a beginner question, but since I am not able to get it working in the intended-fashion, I am hoping somewhere out there is able to point me in the right direction.</p>
  
  <p>What I am trying to achive is a transition of a view inside a view.
  I fundamentally want to replace a view inside a view with another view(controller?!?)  's content.</p>
  
  <p>lets say, I have an image of a book and I want to do a transition inside the book to another page (going from the calendar-view to the detailed daily view for example). I only want the "book-content"(white content area) to be included in that transition, and not the whole book itself(whole screen).</p>
  
  <p>I can do a transition with the same view, no problem, but I dont get it working trying to replace the view with a completly different view. 
  It didnt matter having the views in seperate viewcontrollers, or all the views in one viewcontroller, so I were not able to get it working yet, but even worse, I am running out of ideas.
  So HELP! If please somebody out there could be so kind and tell me what I am doing wrong.
  Suggestions also very much appreciated.
  Thanks!!</p>
