Question

I have the following code:

float yOffset = activeTextView.frame.origin.y - keyboardSize.height + 55;
        CGPoint scrollPoint = CGPointMake(0.0, yOffset);
        [scrollView setContentOffset:scrollPoint animated:YES];

This animates the scrollView in - (void)keyboardWasShown:(NSNotification *)notification

I am trying to return the scrollView to it’s original location after the hiding the keyboard like this:

- (void) keyboardWillHide:(NSNotification *)notification {

    UIEdgeInsets contentInsets = UIEdgeInsetsZero;
    scrollView.contentInset = contentInsets;
    scrollView.scrollIndicatorInsets = contentInsets;

}

But it doesn’t work!

How can I return the UIScrollView and actually the whole screen to its original location so the user will see what he saw before animation of the scrollview?

Answer 1

In your keyboardWasShown: method, you’re setting the contentOffset property ([scrollView setContentOffset:] is equivalent to scrollView.contentOffset). However, in keyboardWillHide:, you’re setting contentInset, which is something completely different (essentially, it’s the amount of internal padding of the scroll view’s content). Try

scrollView.contentOffset = CGPointZero; // non-animated by default

or

[scrollView setContentOffset:CGPointZero animated:YES]; // animated

Also, as NSResponder mentioned, make sure your keyboardWillHide: method is being called.
