How do you stop Interface Builder embedding a control in a UIView when I drag it around?

Question

When I move controls in Interface Builder and pass over a UIView. Is there anyway to stop IB from embedding the control in the UIView and making it a child of the UIView in the tree hierarchy.

BEFORE
+UIView
+UIButton
+UIView

If I move the UIButton with the mouse and place it above the UIView IB will make it a child of the UIView

AFTER
+UIView
  +UIButton
+UIView

Is there anyway to lock the bottom view. I often use them as backgrounds and tint them.

Answer 1

You can reposition without embedding by pressing and holding Cmd while dragging the element.

Edit: This is only confirmed to work with Xcode 7.
