Create informational popup / tooltip in Cocoa

Question

The question title is kind of vague, but I really don't know what the thing is called.

I am trying to create one of those yellow informational popup things. Anyone can tell me what they're called and how I can create them?

No need to apologize - it's hard to google something when you don't know the right keyword. — Sherm Pendley, May 21 '11 at 15:16

That's called a tool tip. You can set the tool tip for any NSView using setToolTip:.

+1 and you can make it show up at a specific point using `addToolTipRect:owner:userData:` http://developer.apple.com/library/mac/documentation/Cocoa/Reference/ApplicationKit/Classes/NSView_Class/Reference/NSView.html#//apple_ref/doc/uid/20000014-BBCHBAHJ – Dave DeLong May 21 '11 at 16:09

You can also use Interface Builder to assign them, in the Identity Inspector. – Dov Jun 09 '12 at 13:01

If you are using NSTextView, you can even set an attribute for a certain range in NSTextstorage, that displays the Tooltip. Something like:

[textStorage addAttribute:NSToolTipAttributeName
                    value:error.description
                    range:range];
