如何在nstextview中设置文本的背景颜色？

Question

I have a nstextview, and I was wondering how to set the background color of it. I've tried quite a few things, but none seem to work. They just set the actually text color. I have a NSColorWell, called colorBox , and the textview is called doc , in case someone wants to know. I use `[self.colorBox color] to get the color in the NSColorWell

Answer 1

NSTextView has backgroundColor property . Try setting it to something else like NSColor.redColor() .

It also has drawsBackground property which need to be set to true to make it work.

let textView1 = NSTextView()
textView1.backgroundColor = NSColor.redColor()
textView1.drawsBackground = true

Answer 2

要更改属性字符串的背景颜色，必须将属性添加到其中：

[mutableAttributedString addAttribute:NSBackgroundColorAttributeName value:[UIColor redColor] range:selectedRange];

Answer 3

If you're using storyboards, TextViews have three sections in the Attributes Inspector, "Text View", "Scroll View", and "View". "Background color" is the fifth option in the "View" section.
