objective-c - Vvidget_GG.framework and Vvidget_GS.framework part of OS X default install?

Question

I downloaded some example code to draw a line graph in Cocoa. The example is not running because Vvidget_GG.framework and Vvidget_GS.framework do not exist. I searched in my /System/Library/Frameworks and /Library/Frameworks folders to add them to my project, but they are not there on my system.

Do these frameworks exist by default on OS X?

Answer 1

它们绝对不是任何 Apple SDK 的一部分——显然，它们是由 Vvidget 出售的。
