IOS登陆+注册+抽奖+排行榜

要求：三个页面（登录页面，pickerView页面，排行榜页面），pickerView页面是三个组件，每个组件显示0-9，点击按钮进行随机，获得的值存入排行榜，排行榜显示大于500的最高的10个分数和对应的用户名，切换页面可以用任何方法（0-9循环显示，登录注销[可以有不同的用户]，判断用户名是否为邮箱[正则表达式]）

说明：
1.要修改xml文件到当前系统桌面，dic.xml保存的是用户名和密码，array.xml是保存的积分榜
2.正则表达式用在注册页面，在注册用户的时候用户名需要经过正则表达式的验证，判断是否是邮箱
3.有一个默认的admin，admin账户
4.排行榜显示是用的tableView显示的

疑惑：
1.如何创建文件在当前项目下
2.为什么view之间传数组传不了，我知道数组要先初始化
3.数组排序，用内置的排序方法，compare：,从大到小用什么参数
4.如何让tableView中的table随array的改变而刷新
