Very simply because I have a situation where real estate is tight. The popup variant always displays the current selection so you need to allocate enough horizontal space for the button to display the widest menu item text. By using the pulldown button, I can just display an icon and "down arrow" on the button, and use more space only when the user changes options. I have a descriptive icon next to each menu item, which gets reflected directly on the button when the menu is closed. Believe me, if I could do something similar with a popup (vs pulldown) button, I would.

If you are not overriding +automaticallyNotifiesObserversForKey:, then
why are you manually sending -willChangeValueForKey: and
-didChangeValueForKey:? You are already benefitting from automatic
KVO support (assuming your accessor is named -interpolationMode).
-willChangeValueForKey: and -didChangeValueForKey: are only for manual
KVO support, which requires overriding
+automaticallyNotifiesObserversForKey: to return NO for the key in
question:

The reason I ask these questions is so that by examining your code, we
may figure out what's going wrong. The crucial step in this process
is the posting of code. ;-)
