Question

I wanted to know when a text is wrapped by the frame of the text view is there any delimiter with which we can identify whether the text is wrapped or not.

Answer 1

You need to consider textView.textContainerInset, also need to round the calculated value since line number definitely is an integer

float rawLineNumber = (textView.contentSize.height - textView.textContainerInset.top - textView.textContainerInset.bottom) / textView.font.lineHeight;
int finalLineNumber = round(rawLineNumber)

In real case, you may see following result rawLineNumber = 3.008099 finalLineNumber = 3 (3 lines)
