I\'ve seen the setContentOffset:animated: method. Is that going to scroll to a specific position, or what does that \"offset\" mean?

    Yes. From the Apple documentation:

    setContentOffset:animated: Sets the offset from the content view’s origin that corresponds to the receiver’s origin.

    You can control the animation using

    [UIView animateWithDuration:1.2 animations:^{_scrollView.contentOffset = CGPointMake(X, Y);}];
