Using Autolayout with UIView embedded in UIScrollView - ios

Question

I have a View embedded inside a Scroll View. I have written code such that when the cursor is placed in a text field (within the View) that is hidden by the keyboard that the screen will readjust such that the text field is no longer hidden. I am using autolayout to do this.
My problem is that when I put the View in the View Controller at the position I want it, there is a lot of additional white space above when I run the simulator. But when the keyboard comes up (and the screen redraws) then I can scroll up and the View Controller no longer has that additional white space.
If I adjust the view so that there isn't any white space (so it appears as on the storyboard) then when the keyboard appears, I cannot scroll to the top of the View.
I assume this has something to do with how the View is centered within the Scroll View but I have tried numerous adjustments on the constraints in the Size Inspector and cannot resolve this. I would really like to fix this in the storyboard (versus through code) if at all possible...
Here is the code:
- (void) keyboardDidShow:(NSNotification *)notification
{
NSDictionary* info = [notification userInfo];
CGRect kbRect = [[info objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue];
kbRect = [self.view convertRect:kbRect fromView:nil];
UIEdgeInsets contentInsets = UIEdgeInsetsMake(0.0, 0.0, kbRect.size.height, 0.0);
self.scrollView.contentInset = contentInsets;
self.scrollView.scrollIndicatorInsets = contentInsets;
CGRect aRect = self.view.frame;
aRect.size.height -= kbRect.size.height;
if (!CGRectContainsPoint(aRect, self.activeField.frame.origin) ) {
[self.scrollView scrollRectToVisible:self.activeField.frame animated:YES];
}
}
- (void) keyboardWillBeHidden:(NSNotification *)notification
{
UIEdgeInsets contentInsets = UIEdgeInsetsZero;
self.scrollView.contentInset = contentInsets;
self.scrollView.scrollIndicatorInsets = contentInsets;
}

Turns out that I was setting the EdgeInsets value too high... when I changed from
UIEdgeInsets contentInsets = UIEdgeInsetsMake(0.0, 0.0, kbRect.size.height, 0.0);
to
UIEdgeInsets contentInsets = UIEdgeInsetsMake(60.0, 0.0, kbRect.size.height, 0.0);
The positioning was improved.
