I have an NSView which contains a variable number of subviews. Is there any way to have the view resize to fit all of its contents?

---

Yes. Get the size of the contents and tell the view to resize to that size.

Not automatically. Just write your own method. Should be easy.

You could try something like this, but you are doing things backwards. Your subviews should be relative to your view not the other way around.

• (void)fitSubviews { NSArray *subviews = [self subviews]; NSRect rect = NSZeroRect; unsigned int i, count = [subviews count]; for (i = 0; i < count; i++) { rect = NSUnionRect(rect, subviews objectAtIndex:i] frame]); } rect = [self convertRect:rect toView:[self superview; [self setFrame:rect]; }

Thanks, I got it. The reason I have to do it this way (I think) is because each of my subviews is the same size (I am doing a page-layout view), and every time a new page gets added, the parent view needs to get taller to encompass the new page.

If you want the window to resize smoothly (e.g. user preferences), use the setFrame:display:animate: instead. – BenoitMarchal
