这个吧，纠结了我一段时间。 下面直接上脚本吧。

using UnityEngine;using UnityEngine.UI;using UnityEngine.EventSystems;using System.Collections;using System.Collections.Generic;public class UICameraTouchController : MonoBehaviour, IDragHandler, IPointerDownHandler, IPointerUpHandler{    public CameraController _camera;// 相机    private RectTransform rectTransform;// 要是一个 全屏大小的image    private Dictionary
   
     touches = new Dictionary
    
     ();    private void Awake()    {        rectTransform = this.GetComponent
     
      ();    }    public void OnPointerDown(PointerEventData eventData)    {        touches[eventData.pointerId] = eventData.position;    }    public void OnPointerUp(PointerEventData eventData)    {        if (_camera != null)        {            _camera.EndDrag();        }        touches.Remove(eventData.pointerId);    }    public void OnDrag(PointerEventData eventData)    {        if(touches.Count == 1)        {            touches[eventData.pointerId] = eventData.position;            Vector2 delta = new Vector2(eventData.delta.x / rectTransform.rect.width * 180.0f, eventData.delta.y / rectTransform.rect.height * -90.0f);            if (_camera != null )            {                _camera.RotateCamera(delta);            }        }    }}
     
    
   

using System.Collections;using UnityEngine;public class CameraController : MonoBehaviour{    public Transform _cameraContainer;// 相机    void Awake()    {        _cameraContainer = ObjectCommon.GetChildComponent
   
    (gameObject, "CameraContainer");    }    void Clear()    {        IsDrag = false;    }      void Update()    {    }    bool IsDrag = true;// 是否在拖拽中    public void EndDrag()    {        IsDrag = false;    }    public void RotateCamera(Vector2 delta)    {        IsDrag = true;        float y = this._cameraContainer.localEulerAngles.y + delta.x;              UITools.SetTransformRotation(this._cameraContainer,new Vector3 (0,y,0));    }}
