Pinch zoom and swipe camera movements in unity3d for Iphone

Hi guys,
  This post is regarding to "pinch zoom and swipe movements for iPhone". I have just searched for all unity forums about pinch zoom and swipe movements in a same script. And here the script about this,

Its C# Script : (Touches.cs)

Note : i took Z-axis (right to left movements) , X-axis (front to back movements) 

using UnityEngine;
using System.Collections;

public class Touches : MonoBehaviour
{
public float minDist = 2.0f;
public float maxDist = 5.0f;
public Transform projectile;
public float speed;
private Vector3 moveVec;
private float startZ;
private float actualDist;
       
void Start ()
{       
    startZ = projectile.position.z;
}
   
void Update ()
{

//This section for move the camera position only limited values . 

// You can Change the values for your requirements.

//Here the camera will move with in your required portion on the screen.

if(projectile.position.z >= 100)
{           
transform.position = transform.position + new Vector3(0.0f,0.0f,-10.0f);
}
else if(projectile.position.z <= -150)
{
transform.position = transform.position + new Vector3(0.0f,0.0f,10.0f);
}
       
if(projectile.position.y >= 140)
{
transform.position = transform.position + new Vector3(0.0f,-10.0f,0.0f);
}
else if(projectile.position.y <= -50)
{
transform.position = transform.position + new Vector3(0.0f,10.0f,0.0f);
}
       
if(projectile.position.x >= 420)
{
transform.position = transform.position + new Vector3(-5.0f,0.0f,0.0f);
}
else if(projectile.position.x <= 85)
{
transform.position = transform.position + new Vector3(5.0f,0.0f,0.0f);
}

// This Section For to move camera according to your swipe on screen.       
if (Input.touchCount == 1 )
{               
Touch touch = Input.GetTouch(0);
switch (touch.phase)
{
case TouchPhase.Began:
dragStartPos = touch.position;
moveVec = Vector2.zero;
break;
           
case TouchPhase.Moved:
Vector3 pos = Camera.main.ScreenToWorldPoint(touch.position);
pos.z = startZ;
projectile.position = Camera.main.ScreenToWorldPoint(touch.position);
//here i gave condition to move camera with in required position
if(projectile.position.z >= -150 && projectile.position.z <= 100)
{
moveVec = -(touch.position - dragStartPos) * speed;
}
break;
           
case TouchPhase.Ended:
dragStartPos = touch.position;
moveVec = Vector2.zero;
break;
}
projectile.Translate(moveVec * Time.deltaTime);
Vector3 val = moveVec * Time.deltaTime;
}

//This section for pinch Zooming on screen.       
if (Input.touchCount == 2)
{
Touch touch = Input.GetTouch(0);
Touch touch1 = Input.GetTouch(1);
if (touch.phase == TouchPhase.Moved && touch1.phase == TouchPhase.Moved)
{
Vector2 curDist = touch.position - touch1.position;
Vector2 prevDist = (touch.position - touch.deltaPosition) - (touch1.position - touch1.deltaPosition);
float delta = curDist.magnitude - prevDist.magnitude;
Camera.main.transform.Translate(0,0,delta * .5f);
}
}
}

Its simple and make it use guys.

Sriram.
