在尝试使用自定义背景编写简单的Cocoa/Applescript时(遵循本教程,http: //www.mere-mortal-software.com/blog/details.php？d = 2007-01-08 ),我得到了在调试器中偶尔出现以下错误:
Error>: kCGErrorIllegalArgument: _CGSFindSharedWindow: WID 3162
Media Center[10234] <Error>: kCGErrorFailure: Set a breakpoint @ CGErrorBreakpoint() to catch errors as they are logged.
所以我设置了一个断点,CGErrorBreakpoint我得到了以下结果:

我不完全确定如何解决这个问题,如果需要,我会提供更多输出信息.
编辑:如果在显示停靠栏时打开应用程序,我会收到错误消息.如果未显示底座,则通常可以正常工作.
