我尝试以编程方式将NSDrawer添加到我应用的主窗口(其中还有NSOutlineView已在IB中设置):

的Ivar:

var dd: NSDrawer? = nil

然后,当点击显示三角形按钮时:

if dd == nil {
            var drawer_rect = NSInsetRect(self.window.frame, 30, 30).size
            drawer_rect.height = 150
            dd = NSDrawer.init(contentSize: drawer_rect, preferredEdge: NSRectEdge.minY)
            dd!.contentView = self.status_scroll
            dd!.parentWindow = self.window
        }

因此,当用户试图披露'抽屉,上面的代码创建一个NSDrawer,然后显示它。一切正常,但Xcode在设置parentWindow时转储了以下内容:

[General] ERROR: Setting <NSOutlineView: 0x100f0b9b0> as the first responder for window <NSDrawerWindow: 0x100fc8900>, but it is in a different window (<NSWindow: 0x6080001e0600>)! This would eventually crash when the view is freed. The first responder will be set to nil.

注释掉parentWindow的设置,没有任何内容被转储到控制台。

NSDrawer已根据Apple documentation弃用。你应该考虑不同的设计。如果您仍然使用NSDrawer,则可能会遇到此类问题。
