OK, I'm having some problem with the UITextView. Here's the issue:

I add some text to a UITextView. The user then double clicks to select something. I then change the text in the UITextView (programatically as above) and the UITextView scrolls to the bottom of the page where there is a cursor.

However, that is NOT where the user clicked. It ALWAYS scrolls to the bottom of the UITextView regardless of where the user clicked.

So here's my question: How do I force the UITextView to scroll to the top every time I change the text? I've tried contentOffset and scrollRangeToVisible. Neither work.

Any suggestions would be appreciated.

UITextView*note;
[note setContentOffset:CGPointZero animated:YES];

This does it for me.

Swift version (Swift 4.1 with iOS 11 on Xcode 9.3):

note.setContentOffset(.zero, animated: true)
