示例代码：（将该脚本绑在一个Lable对象上，即可测试，显示为从1跳到10）

using UnityEngine;
using System.Collections;

public class test : MonoBehaviour 
{
    int result = 0;
    private int start = 1;
    private int end = 10;
    private int jumpTimes = 9;

    private UILabel label = null;
    void Start()
    {
        label = gameObject.GetComponent<UILabel>();
        StartCoroutine(JumpNumber());
    }

    public IEnumerator JumpNumber()
    {
        int delta = (end - start) / jumpTimes;
        result = 0;
        
        for (int i = 0; i < jumpTimes; i++)
        {
            result += delta;
            label.text = result.ToString();
            yield return new WaitForSeconds(1);
        }

        result = end;
        label.text = result.ToString();
        StopCoroutine(JumpNumber());
    }
}

 　　代码中 yield return new WaitForSeconds(1);表示返回1秒，若写成yield return1;表示返回1帧。
