public class PlayerfesText : MonoBehaviour {
    string usrname = "李四";
    int password = 88888;
    // Use this for initialization
    void Start () {
    }
    public void SetNum() {

        PlayerPrefs.SetString("name",usrname);//存取数据
        PlayerPrefs.SetInt("pass",password);
        PlayerPrefs.SetFloat("float",1.23f);
    }
    public void GetNum() {
       string n=  PlayerPrefs.GetString("name");//读取数据
       int num=  PlayerPrefs.GetInt("pass");
        Debug.Log(n+"  "+num);//打印

    }
    public void DeKey()
    {
        //  PlayerPrefs.DeleteKey("name");删除键值
        PlayerPrefs.DeleteAll();//删除键值对
    }
    // Update is called once per frame
    void Update () {
        
    }
}
