要求：三個頁面（登錄頁面，pickerView頁面，排行榜頁面），pickerView頁面是三個組件，每個組件顯示0-9，點擊按鈕進行隨機，獲得的值存入排行榜，排行榜顯示大于500的最高的10個分數(shù)和對應(yīng)的用戶名，切換頁面可以用任何方法（0-9循環(huán)顯示，登錄注銷[可以有不同的用戶]，判斷用戶名是否為郵箱[正則表達式]）

說明：
1.要修改xml文件到當前系統(tǒng)桌面，dic.xml保存的是用戶名和密碼，array.xml是保存的積分榜
2.正則表達式用在注冊頁面，在注冊用戶的時候用戶名需要經(jīng)過正則表達式的驗證，判斷是否是郵箱
3.有一個默認的admin，admin賬戶
4.排行榜顯示是用的tableView顯示的

疑惑：
1.如何創(chuàng)建文件在當前項目下
2.為什么view之間傳數(shù)組傳不了，我知道數(shù)組要先初始化
3.數(shù)組排序，用內(nèi)置的排序方法，compare：,從大到小用什么參數(shù)
4.如何讓tableView中的table隨array的改變而刷新
