NSMenuItem 自定义视图中可编辑的 NSTextField
我有一个 NSView 子类，我想包含一个可编辑的 NSTextField，类似于 Spotlight。
我在选择和突出显示文本字段时遇到了很大的困难。如果我在文本字段的编辑区域上快速单击，我实际上可以输入文本，但它显示为灰色，就好像我正在将文本添加到不是最重要的应用程序的字段中一样。
我尝试使用 viewDidMoveToWindow 来获得视图窗口的焦点，但显然 NSMenuItem 的窗口是碳窗口，不能很好地处理按键。
长话短说，要成功完成这项工作，有什么好方法呢？我知道 Spotlight 是一个无边框窗口，但这不适合我的目的。
任何和所有建议都会非常有帮助。
I have a subclassed NSView that I would like to contain an editable NSTextField, similar to Spotlight.
I am having significant difficult getting the text field to select and highlight. If I click quickly and rapidly over the editing area of the textfield, I can actually enter text, but it appears greyed out, as though I am adding text to a field of an app that is not foremost.
I have tried to get focus of the View's window using viewDidMoveToWindow, but apparently NSMenuItem's windows are carbon windows that don't handle keys very well.
Long story short, what is a good way to go about making this work successfully? I know that Spotlight is a borderless window, but that is not suitable for my purposes.
Any and all suggestions would be very helpful.

经过大量研究后，有两件事是普遍共识：
(1) 如果您发现自己正在寻找特殊方法来子类化内置 UI 元素，那么您可能做错了什么，或者至少有更好的方法做你想做的事情的方法。
(2) 遵循接口指南的原因是为了更好地兼容未来。无法保证子类 UI 元素将与操作系统的未来版本兼容。
Brass Tacks - 通常不建议对 UI 元素进行子类化。
After much research, two things are common consensus:
(1) If you find yourself looking for ways to subclass a built-in UI element for special the chances are that you're doing something wrong, or at very least, there is a better way to do what you're trying to do.
(2) The reason to follow the interface guidelines is to be more future-compatible. There is no guarantee that a sub-classed UI element will be compatible with future versions of the OS.
Brass Tacks - subclassing UI elements is generally not advised.
