问题说明
我有一个UITextView文本编辑。默认情况下，它在文本周围有一个小的边距。我想将边距增加几个像素。
I have a UITextView for text editing. By default, it has a small margin around the text. I want to increase that margin by a few pixels.
contentInset属性提供了边距，但它不会更改文本换行宽度。文本以相同的宽度包装，额外的边距只是导致视图水平滚动。
The contentInset property gives me margins, but it does not change the text "wrap width". The text is wrapped at the same width, and the extra "margin" just causes the view to scroll horizontally.
有一种方法可以使UITextView具有一定的宽度显示具有较窄换行宽度的文本？
Is there a way to make a UITextView of a certain width display the text with a narrower "wrap width"?

从iOS 7开始，您可以使用 textContainerInset 属性：
Starting from iOS 7 you can use textContainerInset property:
textView.textContainerInset = UIEdgeInsetsMake(0, 20, 0, 20);
