How to scroll to a specific element in ScrollRect with Unity UI?

Question

I built a registration form for a mobile game using Unity 5.1. To do that, I use Unity UI components: ScrollRect + Autolayout (Vertical layout) + Text (labels)

Answer 1

In case anyone looking for a smooth scroll (using lerp).

[SerializeField]
private ScrollRect _scrollRectComponent; //your scroll rect component
[SerializeField]
RectTransform _container; //content transform of the scrollrect
private IEnumerator LerpToChild(RectTransform target)
{
    Vector2 _lerpTo = (Vector2)_scrollRectComponent.transform.InverseTransformPoint(_container.position) - (Vector2)_scrollRectComponent.transform.InverseTransformPoint(target.position);
    bool _lerp = true;
    Canvas.ForceUpdateCanvases();

    while(_lerp)
    {
        float decelerate = Mathf.Min(10f * Time.deltaTime, 1f);
        _container.anchoredPosition = Vector2.Lerp(_scrollRectComponent.transform.InverseTransformPoint(_container.position), _lerpTo, decelerate);
        if (Vector2.SqrMagnitude((Vector2)_scrollRectComponent.transform.InverseTransformPoint(_container.position) - _lerpTo) < 0.25f)
        {
            _container.anchoredPosition = _lerpTo;
            _lerp = false;
        }
        yield return null;
    }
}
