哪个 NSTextView 是第一响应者？
我正在进行 Cocoa 编程练习，我需要能够确定当前正在编辑两个 NSTextView 对象中的哪一个。我认为这与找到第一响应者并检查它是否等于一个文本字段或另一个文本字段有关，但我无法完全让它工作。任何帮助将不胜感激。
I'm working on a Cocoa programming exercise, and I need to be able to determine which of two NSTextView objects is currently being edited. I think it's something to do with finding the first responder and checking to see if it's equal to one text field or another, but I can't quite get it to work. Any help would be appreciated.

我建议您阅读 Cocoa 事件处理指南，特别是名为 响应程序相关任务。您将找到您需要的所有信息。
I suggest you to read the Cocoa Event-Handling Guide, and especially the section called Responder-Related Tasks. You will find all the information you need.
