Variable height UITextView

Question

Im embedding a text view inside a table view cell. This text view is meant for writing long text.

How do it get a variable height uitextview that expands automatically when the entered text exceeds the assigned height of the uitextview. It must work like composing a message in the Mail app.

Set and implement delegate of UITextView delegate protocol
Check size of UITextView.contentSize. If it's height parameter has changed then you should expand table view cell: 2.1 Reload particular cell. 2.2 Return new height value in UITableViewDelegate method.

Take a look at this SO question.

You can take the font property from UITextView to use in the sizeWithFont: method.

You should implement the UITextViewDelegate protocol and every time the text view changes, that is, when – textViewDidChange: gets called you should reload the cell to adjust it to the content's size.

To reload a specific row, you can use – reloadRowsAtIndexPaths:withRowAnimation:.

I managed this via Storyboard using the Content Hugging Priority property.

In IB I set the Text View height to a default value and gave this a priority of 250 (Low).

Text View Height1

I then set the Content Hugging Priority to 1000. The view resized to fit the text exactly I wanted. Content Hugging Priority2

Hope this helps
