CocoaAsyncSocket使用
代理的.h文件
//GCDAsyncSocketDelegate执行代理对象 #import <Foundation/Foundation.h> #import "CocoaAsyncSocket.h" typedef void(^DidReadData)(NSDictionary* didReadData); /** * GCDAsyncSocketDelegate执行代理对象 */ @interface NSObjectGCDAsyncSocket : NSObject<GCDAsyncSocketDelegate> /** * 接收到数据的处理 */ @property(nonatomic,copy)DidReadData didReadData; /** * 发送的数据 如果添加新键值则需要先开辟内存 */ @property(nonatomic,retain)NSMutableDictionary* writeData; /** * 发送链接请求 */ -(BOOL)startConnect; /** * 单例 */ +(NSObjectGCDAsyncSocket*)defaultSocket; @end

使用
创建对象 socket=[NSObjectGCDAsyncSocket defaultSocket]; 填写发送的数据 socket.writeData=[NSMutableDictionary dictionaryWithDictionary:dictionary]; 处理收到的数据 socket.didReadData=^(NSDictionary* didReadData){.......} 开始链接 [socket startConnect]; 添加CocoaAsyncSocket 第三库 链接地址:https://github.com/robbiehanson/CocoaAsyncSocket
