uitextview in section header: how to adjust height to content

Margie781

I want to make a UITextView in my section header adjust its height to its content. I tried setting its numberOfLines to 0, but that didn't work. Is there any way to do this?

Create a subclass of UITextView and add the following code in the layoutSubviews() method:

override func layoutSubviews() {
   super.layoutSubviews()
   self.sizeToFit()
}

This will make the text view adjust its height to its content.

Here are a few ways to make a UITextView in a section header adjust its height to its content:

Use Auto Layout constraints to tie the UITextView's top, bottom, and leading (or trailing) edges to the edges of the view container.
Wrap the UITextView in a UIView and use Auto Layout constraints to tie the UIView's top, bottom, and leading (or trailing) edges to the edges of the view container.
Implement the UITextViewDelegate protocol's textViewDidChange: method and use that method to adjust the UITextView's height to its content.
Use a third-party library that provides auto-sizing capabilities for UITextView, such as IQTextView.
