使用

建立對象    socket=[NSObjectGCDAsyncSocket defaultSocket];填寫發送的資料socket.writeData=[NSMutableDictionary dictionaryWithDictionary:dictionary];處理收到的資料        socket.didReadData=^(NSDictionary* didReadData){.......}開始連結[socket startConnect];添加CocoaAsyncSocket 第三庫 連結地址:https://github.com/robbiehanson/CocoaAsyncSocket
