Question

在自定义NSTableCellView上使用NSTextField。

当用户在单元格上的任意位置按下时，我希望NSTextField成为第一响应者。当我这样做时，文本消失了，用户需要按任意键盘键才能使其返回，如何禁用此行为？

代码：

    override func mouseDown(with event: NSEvent) {
        super.mouseDown(with: event)
        if (event.clickCount == 2) {
            self.beginEditing()
        } else {
            self.endEditing()
        }
    }

    private func beginEditing() {
        self.lblTitle.isEditable = true
        self.window?.makeFirstResponder(self.lblTitle)
        self.lblTitle.backgroundColor = Colors.clear
        self.lblTitle.borderColor = Colors.clear
    }

    private func endEditing() {
        self.lblTitle.isEditable = false
        self.lblTitle.backgroundColor = Colors.red
    }
