I want to change the height constraint of a UITextView programmatically so I set the constraint as an outlet in my controller like this:

Answer 1

Try setting the constant in viewDidLayoutSubviews instead.

Note that using the text view's contentSize property to set the text view's height does not work in iOS 7. See https://stackoverflow.com/a/18837714/1239263
