Can't get View to be drawn in NSScrollView

Question

I am confused about how to implement a NSScrollView in the most basic way, so I will describe exactly what I do and hope that it is just to late for me to find my error:

1. Create Xcode project.
2. Adding a NSScrollView into MainMenu.xib.

3. Creating new class inherited from NSView with the drawing method:

   (void)drawRect:(NSRect)dirtyRect
   {
   [super drawRect:dirtyRect];
   [[NSColor redColor] set];
   NSRectFill(dirtyRect);
   }
   

4. Define the view of the NSScrollView to be that new class.

I expected to see a NSScrollView with a red background. Instead, I see the scroll view with no modification.

Answer 1

The problem is auto layout. Turn it off and it will work fine.
