想要苹果或安卓那种手指滑动屏幕的效果。

这里是原文，使用的是scrollview来演示。

它是iphone的开发，我发一下android上的，选择里边的item还没添加进来。

using UnityEngine;using System.Collections;public class TestUI : MonoBehaviour {        public Vector2 scrollPosition = Vector2.zero;    public float scrollVelocity = 0f;    public float timeTouchPhaseEnded = 0f;    public float inertiaDuration = 0.5f;        public Vector2 lastDeltaPos;        // Use this for initialization    void Start () {        }        void OnGUI()    {        scrollPosition = GUI.BeginScrollView(new Rect(100, 40, 600, 400), scrollPosition, new Rect(0, 0, 500, 1600), false, true);                for (int i = 0; i < 32; i++)        {            GUI.Button(new Rect(0, i*50, 400, 50), "Button"+i);        }        GUI.EndScrollView();    }        // Update is called once per frame    void Update ()     {        if (Input.touchCount > 0)        {            if (Input.GetTouch(0).phase == TouchPhase.Moved)            {                scrollPosition.y += Input.GetTouch(0).deltaPosition.y;                lastDeltaPos = Input.GetTouch(0).deltaPosition;            }                    else if (Input.GetTouch(0).phase == TouchPhase.Ended)            {                print ("End:"+lastDeltaPos.y+"|"+Input.GetTouch(0).deltaTime);                if (Mathf.Abs(lastDeltaPos.y)> 20.0f)                {                    scrollVelocity = (int)(lastDeltaPos.y * 0.5/ Input.GetTouch(0).deltaTime);                    print(scrollVelocity);                }                timeTouchPhaseEnded = Time.time;            }        }        else        {            if (scrollVelocity != 0.0f)            {                // slow down                float t = (Time.time - timeTouchPhaseEnded)/inertiaDuration;                float frameVelocity = Mathf.Lerp(scrollVelocity, 0, t);                scrollPosition.y += frameVelocity * Time.deltaTime;                                if (t >= inertiaDuration)                    scrollVelocity = 0;            }        }    }}
