1. What‘s BMReachability?

BMReachability monitors the reachability of domains for both WWAN and WiFi network interfaces. This is a drop-in replacement for AFNetworking‘s Reachability class. It is ARC-compatible, and it uses the delegate methods to notify of network interface changes. It supports the use of blocks for when the network becomes reachable and unreachable. It provides monitor 2G/3G/4G network interface changes.

2. System Requirements

requires iOS 7.0 minimum deployement version.

3. How To Use

Just #import the BMReachability.H header, add BMAddNetworkStatusObserver(self) in your code, and implement BMNetworkStatusProtocol.

typedef NS_ENUM(NSInteger, BMNetworkReachabilityStatus) { 

     BMNetworkReachabilityStatusUnknown = -1, 

    BMNetworkReachabilityStatusNotReachable = 0, 

    BMNetworkReachabilityStatusReachableViaWWAN = 1,  

    BMNetworkReachabilityStatusReachableViaWiFi = 2,

    BMNetworkReachabilityStatusReachableVia2G = 3, 

    BMNetworkReachabilityStatusReachableVia3G = 4, 

    BMNetworkReachabilityStatusReachableVia4G = 5, 

};

Example:

• (void)dealloc{ BMRemoveNetworkStatusObserver(self); }

• (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view, typically from a nib. [self button]; BMAddNetworkStatusObserver(self); }

• (void)networkStatusDidChangedFromStatus:(BMNetworkReachabilityStatus)fromStatus toStatus:(BMNetworkReachabilityStatus)toStatus{

  NSLog(@"*****************************************"); if (fromStatus != toStatus) { NSLog(@"========状态改变了啊========="); }

  NSLog(@"fromStatus: %@ toStatus: %@",@(fromStatus),@(toStatus));

  NSString *statusStr = [[BMEnvObserverCenterNetworkStatus defaultCenter] currentNetWorkStatusString]; NSLog(@"当前网络状态为: %@",statusStr);

}

Warning: You must remove Network Status Observer
