I am using a UITextView. I want to autoscroll the textview's text with animation from top to bottom for one time. How can I achieve this?

Try this:

Swift:

let range = NSMakeRange(textView.text.characters.count - 1, 0)
textView.scrollRangeToVisible(range)

Objective C:

NSRange range = NSMakeRange(textView.text.length -1, 1);
[textView scrollRangeToVisible:range];

 if(textView.text.length > 0 ) {
    NSRange bottom = NSMakeRange(textView.text.length -1, 1);
    [textView scrollRangeToVisible:bottom];
 }

You should animate the UITextView's contentOffset property.

Objective-C

[UIView animateWithDuration:{duration} animations:^{
    [textView setContentOffset:CGPointMake(0, textView.contentSize.height - textView.frame.size.height)];
}]

Swift

UIView.animate(withDuration: {duration}) {
    textView.setContentOffset(CGPoint(x: 0, y: textView.contentSize.height - textView.frame.height), animated: false)
}
