iOS Network monitoring method

Method One (official):

Reachability

================================================================================

Frame Address: Https://developer.apple.com/library/ios/samplecode/Reachability/Reachability.zip

How to use

1> Adding a networked status listener object

@property (nonatomic, strong) reachability *reach;

2> Instantiating listener objects

Self.reach = [reachability reachabilitywithhostname:@ "www.baidu.com"];

3> Determining the status of networking

-(void) netwrokstatuschanged {

Switch (self.reach.currentReachabilityStatus) {

Case Notreachable:

Sjlog (@ "No Internet connection");

Break

Case Reachableviawifi:

Sjlog (@ "internet via Wi-Fi");

Break

Case Reachableviawwan:

Sjlog (@ "via 3G Internet");

Break

Default

Break

}

}

4> real-time monitoring of network status using notification hubs

[[Nsnotificationcenter Defaultcenter] Addobserver:selfselector: @selector (netwrokstatuschanged) Name: Kreachabilitychangednotification Object:nil];

[Self.reach Startnotifier];

-(void) Dealloc {

Registers the specified notification listener

[[Nsnotificationcenter Defaultcenter] removeObserver:selfname:kReachabilityChangedNotification Object:nil];

}

method Two (AFN):

Managers who have access to network monitoring

Afnetworkreachabilitymanager *mgr = [Afnetworkreachabilitymanager Sharedmanager];

Set up processing after a change in network status

[Mgr setreachabilitystatuschangeblock:^ (afnetworkreachabilitystatus status) {

Switch (status) {

Case Afnetworkreachabilitystatusunknown://Unknown network

Sjlog (@ "Unknown network");

Break

Case afnetworkreachabilitystatusnotreachable://No network (off-grid)

Sjlog (@ "No network detected");

Break

Case Afnetworkreachabilitystatusreachableviawwan://Phone comes with network

Sjlog (@ "via 3G Internet");

Break

Case Afnetworkreachabilitystatusreachableviawifi://WIFI

Sjlog (@ "internet via Wi-Fi");

Break

}

}];

Start monitoring

[Mgr Startmonitoring];
