Reduce Draw call for Multiple GUI Textures with same Texture

Question

I have multiple GUI Textures with same texture in my game. It results large number of DrawCalls . How to reduce DrawCalls using common textures ?

Example code

 using UnityEngine;
 using System.Collections;
  
 public class Example : MonoBehaviour 
 {

   public GUISkin MyGUISkin;

   void OnGUI()

     {

       GUI.Box ( new Rect ( Screen.width*0.1f,Screen.height*0.12f,Screen.width*0.49f,Screen.height * 0.58f),"",MyGUISkin.customStyles[1]);

       GUI.Box ( new Rect ( Screen.width*0.1f,Screen.height*0.22f,Screen.width *0.49f,Screen.height * 0.58f),"",MyGUISkin.customStyles[1]);

     }


  }

You can't do that with OnGUI code. You'll have to use something else, like a third-party GUI system.

Third-party solutions like NGUI and EZGUI build their UI in world space and use Texture Atlases and a common material so that drawcalls batch. More info:
