This is what I am doing to set max number of lines :
self.text_description.textContainer.maximumNumberOfLines = 2 self.text_description.layoutManager.textContainerChangedGeometry(self.text_description.textContainer) When 3rd line is about to get started, the cursor disappears. To put it back I have to tap backspace.

Assuming, in the text view cursor doesn't stays behind the keyboard. I have written a helper method that makes UITextField text scroll to end of text.
- (void)scrollToCaretInTextView:(UITextView *)textView animated:(BOOL)animated { CGRect rect = [textView caretRectForPosition:textView.selectedTextRange.end]; //Get the content size of textview rect.size.height += textView.textContainerInset.bottom; [textView scrollRectToVisible:rect animated:animated]; } Answers 2
I don't quite sure what you are expecting. If you want two lines max, there should be no 3rd line.
Use this:
self.text_description.textContainer.maximumNumberOfLines = 2 self.text_description.textContainer.lineBreakMode = .byTruncatingTail Limit the number of lines for UITextview
It seems what you actually want is a textview with two lines height? If that is true, try this in you view controller.
self.text_description = UITextView(frame: CGRect(x: 100.0, y: 100.0, width: 200.0, height: 28.0)) self.text_description.backgroundColor = #colorLiteral(red: 0.8039215803, green: 0.8039215803, blue: 0.8039215803, alpha: 1) self.view.addSubview(self.text_description)
