I have a UITableViewCell subclass that contains a UITextView where scrolling is turned off. I set its frame like this, in my table view cell layoutSubviews method:
I had the same issue and resolved it working on the textView padding (in swift5):
yourTextView.textContainerInset = UIEdgeInsets(top: 5, left: 5, bottom: 5, right: 5)
Hope it can help :)
