Swift 将文本颜色更改为深色/浅色模式

Question

I am trying to change the text color in a UITextView from light grey to white/black.

So the new text color should be white when the dark mode is on and the text color should be black when the light mode is on.

Answer 1

You can set the UIColor to.label

textView.textColor = .label

This should use the system label colour which is back against a white background and vice versa

You can also create your own dark/light colours in the assets file.

And then use them in code or the interface builder.

textView.textColor = UIColor.init(named: "myBlueColor")
