[英]NSTextView not working

Hi Community, 嗨，社区，

I'm working with a NSTextView, and I can't tell you how frustrating it is. 我正在使用NSTextView，但无法告诉您它有多令人沮丧。 I'm using NSAttributedStrings, so I've set the textStorage to a variable, told it to begin editing, and then I've been using appendAttributedString on the textStroage. 我正在使用NSAttributedStrings，所以我已经将textStorage设置为一个变量，告诉它开始编辑，然后我一直在textStroage上使用appendAttributedString。 The first time I click the button to update the NSTextView, I get this error message: 第一次单击按钮更新NSTextView时，出现以下错误消息：

-[NSNull _isDefaultFace]: unrecognized selector sent to instance 0x7fff70bdefa0 -[NSNull _isDefaultFace]：无法识别的选择器已发送到实例0x7fff70bdefa0

the second time I click the button, the NSTextView goes completely blank, and when I click it (as if trying to select it's text), I get this message: 第二次单击该按钮时，NSTextView完全变为空白，并且当我单击它时（好像试图选择它的文本），我收到以下消息：

_NSLayoutTreeLineFragmentRectForGlyphAtIndex invalid glyph index 0 _NSLayoutTreeLineFragmentRectForGlyphAtIndex无效的字形索引0

What could be causing this?? 是什么原因造成的？ I've been trying to get this work for a few hours now, so any help would be greatly appreciated. 我一直在努力进行这项工作了几个小时，因此，我们将不胜感激。 Thanks! 谢谢！

I figured it out. 我想到了。 I have been trying to use two different font sizes and the NSTextView wasn't liking it 我一直在尝试使用两种不同的字体大小，但NSTextView不喜欢它
