再用Udp--聊天工具

加入AsynScoket   ( 要用到里边的Udp)    导入CFNetwork.framework库

------顶上加UINavigationControlle-------------

1.第一个页面ViewController中

　　　　UI　　   ipField输入框-----输入对方ip

　　　　Event    beginChat按钮点击事件-----跳转到第二个页面，并把ip字符串传过去

2.第二个页面ChatViewController中

　　　　UI　   　_tableView表单-----显示双方对话    

　　　　      　　sendView------自己操作模块

　　　　　　　　　  　--------sendField输入框-----输入对话

　　　　　　　　  　　--------rightButton按钮-----发送对话

　　　　　　　　  　　--------leftButton按钮-----收回键盘

　     　Scoket　　 sendSocket-----发送端       (F++)

　　　　　        　recvSocket-----接收端

　　　　Data    　   　dataArray

　　　　Noti     UIKeyboardWillShowNotification

　　　　　　　　UIKeyboardWillHideNotification

　　　　Event    sendText-----发送对话

　　　　　　　　resignKeyBoard-----让键盘消失

           delegate     UITableViewDelegate,UITableViewDataSource,AsyncUdpSocketDelegate

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

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

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

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

3.封装ChatCell

　　　UI     leftBubble-------左对话UIImageView

　　　　　　rightBubble

　　　　　　leftLabel-------左对话

　　　　　　rightLabel
