創建網絡監聽者管理者對象
AFNetworkReachabilityManager *manager = [AFNetworkReachabilityManager sharedManager];
設置監聽
網絡狀態
//顯然是枚舉值
typedef NS_ENUM(NSInteger, AFNetworkReachabilityStatus) {
AFNetworkReachabilityStatusUnknown? ? ? ? ? = -1,//未識別的網絡
AFNetworkReachabilityStatusNotReachable? ? = 0,//不可達的網絡
AFNetworkReachabilityStatusReachableViaWWAN = 1,//2G,3G,4G...
AFNetworkReachabilityStatusReachableViaWiFi = 2,//wifi網絡
}
-設置網絡監聽
[manager setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {
switch (status) {
case AFNetworkReachabilityStatusUnknown:
NSLog(@"未識別的網絡");
break;
case AFNetworkReachabilityStatusNotReachable:
NSLog(@"不可達的網絡(未連接)");
break;
case AFNetworkReachabilityStatusReachableViaWWAN:
NSLog(@"2G,3G,4G...的網絡");
break;
case AFNetworkReachabilityStatusReachableViaWiFi:
NSLog(@"wifi的網絡");
break;
default:
break;
}
}];
3.開始監聽
[manager startMonitoring];
