Q: Cocoa Merging Custom Views Currently, I have an NSStatusItem that, when clicked, shows a custom view below it. The view contains some information and text fields. What I need is for a separate custom view to merge with the first and appear below it, as in further down the screen, not on top or behind the original view. This needs to be a separate view because there are actually several custom view that will be appended depending on what the user does in the first view. I would like to be able to independently add or remove each of these without affecting the others. I've dug through apple documentation but I haven't found anything about putting one custom view inside another programatically.

A: NSView has an addSubview:positioned:relativeTo: method you can use to add and order views to appear above or below each other. Use superview: to access this method on a container from any of its subviews.
Edit:
Try adding both views to an NSSplitView with a hidden divider. To hide the divider, subclass NSSplitView and override the dividerThickness: method to return 0;
