How to show the share button in Mountain Lion?

Question

Mountain Lion offers a built-in sharing button that reveals a menu of sharing services appropriate for the app:

Answer 1

Note that if you're trying to add this button via Interface Builder:

1. Select the button
2. Switch to Attributes inspector
3. Delete the button Title
4. Insert: NSShareTemplate as the Image name.

It doesn't look right to me in XCode, but works fine when run.

PS - This appears to be a case where you need to use the System Icon string value (NSShareTemplate) instead of the constant (NSImageNameShareTemplate).
