推荐答案
无法捕获屏幕上看不到的NSWindow的内容。当一个窗口被最小化/隐藏/无论什么时，可视表示被删除以节省内存。
It isn't possible to capture the contents of an NSWindow which isn't visible on-screen. When a window is minimized/hidden/whatever, the visual representation is dropped to save memory.
（不确定如何管理它，如果在你对窗口系统有更深入的了解。我只是从经验中知道这一点，试图用CamTwist和BoinxTV捕捉窗户。）
(Not sure on exactly how this is managed, feel free to chime in if you have a deeper knowledge of the window system. I only know this from experience, trying to capture windows with CamTwist and BoinxTV.)
