title: Fix objects inside subview into place
body: <p>How can I fix objects inside a view to a position? What I mean is: I have a subview which includes multiple elements for example an image and a textfield. Those subviews mustn't change their aspect ratio. I know I can set that via auto-layout. But how can I set that all the elements in the subview stick relative to their position inside of that subview? So that if I resize the subview (while remaining in their aspect ratio) the content of it will look the same just up- or downscaled? </p>

  <p><strong>UPDATE:</strong> This is how it looks like. The white area in the middle is the 'subview', and the textfield together with the labels the 'content': </p>

  <p>I have a constraint saying that the 'subview' should keep its aspect ratio. And I just want the 'content' to resize accordingly.
  If I try to auto-layout the textfields and labels to 'subview' I get many weird errors. Isn't there any easier method? I mean it's just resizing and not some complex UI changes.</p>
