检查是否已编辑NSTextView [英] Check if NSTextView has been edited

问题描述

是否有办法在NSTextView被修改时收到通知？在NSTextField中，我只是设置了默认发送操作的目标并且工作正常，但我没有在NSTextView上看到任何已发送的操作。

Is there a way to get notified when a NSTextView gets modified?. In a NSTextField I just set the target for the default sent action and works perfectly, but I don't see any sent actions on a NSTextView.

推荐答案

加油吧。轮询？ 真的吗？
NSTextView继承自NSText，符合NSTextDelegate协议。在文档中查找。您正在寻找的方法是： - （void）textDidChange：（NSNotification *）aNotification 您可以在TextView的委托中实现，也可以通过注册NSTextDidChangeNotification来获取通知。

Come on guys. Polling? Really? NSTextView inherits from NSText, which conforms to the NSTextDelegate protocol. Look it up in the docs. The method you are looking for is: - (void)textDidChange:(NSNotification *)aNotification which you can either implement in your TextView's delegate or get by registering for a "NSTextDidChangeNotification" notification.
