I have 3 views:

• a UIImageView (blank, no image set)
• a UITextView with isScrollEnabled set to false
• a UIView container (gray background) that contains the UIImageView and UITextView

I'm trying to get the container to resize based on the UITextView's contents. It works well — but as soon as I set an image, the container seems to resize based on the UIImageView.

Shorter text	Longer text	After setting image

I do want the UIImageView to grow and fill the container view's height, though. I just don't want it to stretch the container view. That's the UITextView's job. Here's what my constraints look like:

Text View:

CodePudding user response：

In my opinion, you should use constraints to resolve your problem! set text view constraint height equal view (or set equal top and bottom) height constraint and set static image view constraint height (ex: imageView height constraints = 250)
