如何使NSTextView随文本一起增长? [英] How do I make NSTextView grow with text?

问题描述

我正在创建一个简单的文字处理器，用户可以在其中向NSView添加一个文本框，类似于Pages中的功能.问题在于，无论用户输入多少文本，添加时它将保持相同的大小.我希望它随着用户输入文本的增长而增长，我已经尝试过使用

I am creating a simple word processor where it's possible for the user to add a text box to an NSView, similar to the function in Pages. The problem is that when it's added it will stay the same size no matter how much text the user inputs. I want it to grow as the user inputs text, I have tried with this GitHub project but when I use it the text field only expands when I have deleted all the text, as if the code doesn't react before the textDidEndEditing method. After working a bit with NSTextView I found that it would be more suitable for the task, but I still can't make it work. I'm running Mavericks and Xcode 5.0.1.

希望有人可以帮助我！

您必须将其放入NSScrollView中.行为与UITextView中的行为不同(如果您具有iOS背景).

You have to put it into a NSScrollView. The behavior is not the same as in UITextView (if you have a iOS background).
