如何根据文本长度使UITextView高度动态?

如何根据文本长度使UITextView高度动态?

问题描述:

正如你在这张图片中看到的那样

As you can see in this image

UITextView 根据文字长度改变它的高度,I想要根据文字长度调整它的高度。

the UITextView changes it's height according to the text length, I want to make it adjust it's height according to the text length.

*我看到了其他问题,但那里的解决方案对我不起作用

此工作对我来说,所有其他解决方案都没有。

this Works for me, all other solutions didn't.

func adjustUITextViewHeight(arg : UITextView)
{
    arg.translatesAutoresizingMaskIntoConstraints = true
    arg.sizeToFit()
    arg.scrollEnabled = false
}

在Swift 4中, arg.scrollEnabled = false 的语法已更改为 arg.isScrollEnabled = false

In Swift 4 the syntax of arg.scrollEnabled = false has changed to arg.isScrollEnabled = false.
