基於AFNetworking的網絡判斷【原創】

首先導入AFNetworking第三方框架，而後將下面的.h和.m放在你新建的類中即可

GGNetworkJudge.h   在最後會有Singleton.h頭文件代碼

 1 #import <Foundation/Foundation.h>
 2 #import "AFNetworkReachabilityManager.h"
 3 #import "Singleton.h" //此處是將一個普通類轉化爲單例類的頭文件
 4 
 5 @interface GGNetworkJudge : NSObject
 6 
 7 singleton_interface(GGNetworkJudge);
10 
11 //監測網絡狀態
12 - (void)checkNetworkStatus;
13 
14 @end

 

GGNetworkJudge.m
