加入AsynScoket ? ( 要用到里邊的Udp) ? ?導入CFNetwork.framework庫

------頂上加UINavigationControlle-------------

1.第一個頁面ViewController中

　　　　UI　　 ? ipField輸入框-----輸入對方ip

　　　　Event ? ?beginChat按鈕點擊事件-----跳轉到第二個頁面，并把ip字符串傳過去

2.第二個頁面ChatViewController中

　　　　UI　 ? 　_tableView表單-----顯示雙方對話 ? ?

　　　　 ? ? ?　　sendView------自己操作模塊

　　　　　　　　　 ?　--------sendField輸入框-----輸入對話

　　　　　　　　 ?　　--------rightButton按鈕-----發送對話

　　　　　　　　 ?　　--------leftButton按鈕-----收回鍵盤

　 ? ? 　Scoket　　 sendSocket-----發送端 ? ? ? (F++)

　　　　　 ? ? ? ?　recvSocket-----接收端

　　　　Data ? ?　 ? 　dataArray

　　　　Noti ? ??UIKeyboardWillShowNotification

　　　　　　　　UIKeyboardWillHideNotification

　　　　Event ? ?sendText-----發送對話

　　　　　　　　resignKeyBoard-----讓鍵盤消失

? ? ? ? ? ?delegate ? ??UITableViewDelegate,UITableViewDataSource,AsyncUdpSocketDelegate

　　　　　　　　　　　　----UITableViewDelegate----- (CGFloat)tableView:?heightForRowAtIndexPath:

　　　　　　　　　　　　----UITableViewDataSource------ (NSInteger)tableView:?numberOfRowsInSection:

　　　　　　　　　　　　　　　　　　　　　　　　　　------- (UITableViewCell*)tableView:?cellForRowAtIndexPath:

　　　　　　　　　　　　----AsyncUdpSocketDelegate------(BOOL)onUdpSocket:?didReceiveData:?withTag:?fromHost:?port:

3.封裝ChatCell

　　　UI ? ? leftBubble-------左對話UIImageView

　　　　　　rightBubble

　　　　　　leftLabel-------左對話

　　　　　　rightLabel

4.代碼來了-----viewController不寫了
