CocoaAsyncSocket使用

代理的.h文件

//GCDAsyncSocketDelegate執行代理對象#import <Foundation/Foundation.h> #import "CocoaAsyncSocket.h"typedef void(^DidReadData)(NSDictionary* didReadData); /*** GCDAsyncSocketDelegate執行代理對象*/ @interface NSObjectGCDAsyncSocket : NSObject<GCDAsyncSocketDelegate> /*** 接收到數據的處理*/ @property(nonatomic,copy)DidReadData didReadData; /*** 發送的數據 如果添加新鍵值則需要先開辟內存*/ @property(nonatomic,retain)NSMutableDictionary* writeData; /*** 發送鏈接請求*/ -(BOOL)startConnect; /*** 單例*/ +(NSObjectGCDAsyncSocket*)defaultSocket;@end

.m文件

使用

創建對象socket=[NSObjectGCDAsyncSocket defaultSocket]; 填寫發送的數據 socket.writeData=[NSMutableDictionary dictionaryWithDictionary:dictionary]; 處理收到的數據socket.didReadData=^(NSDictionary* didReadData){.......} 開始鏈接 [socket startConnect]; 添加CocoaAsyncSocket 第三庫 鏈接地址:https://github.com/robbiehanson/CocoaAsyncSocket 轉載自螻蟻之毒
