I am using a text view as a comment composer.
In the properties inspector I can\'t find anything like a border style property so that I can make use a rounded rect,
You can create a Text Field that doesn't accept any events on top of a Text View like this:
CGRect frameRect = descriptionTextField.frame;
frameRect.size.height = 50;
descriptionTextField.frame = frameRect;
descriptionTextView.frame = frameRect;
descriptionTextField.backgroundColor = [UIColor clearColor];
descriptionTextField.enabled = NO;
descriptionTextView.layer.cornerRadius = 5;
descriptionTextView.clipsToBounds = YES;
