Detecting Network status

In the network application, the network status of the user device needs to be monitored in real time to

Let users know their network status, to prevent some misunderstanding (such as strange application is not good)

Intelligent processing based on the user's network status, saving user traffic and improving the user experience

WIFI\3G network: Automatically download HD images

Low-speed network: Download thumbnails only

No network: Show only cached data that is offline

1. Using the afnetworking framework

-(void  ) afnmonitoring { Afnetworkreachabilitymanager  *manager = [Afnetworkreachabilitymanager            Sharedmanager]; [Manager setreachabilitystatuschangeblock:  ^ @ " ------current network status%ZD      ,status);        }]; [Manager startmonitoring];}  

typedef ns_enum (Nsinteger, afnetworkreachabilitystatus) {    Afnetworkreachabilitystatusunknown          =- 1,// Unknown network    afnetworkreachabilitystatusnotreachable     0,// No network    1,// cellular network    2,//WiFi network }

2. Use Apple's official reachability

：

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

- (void) Getnetworkstatus {if([reachability reachabilityforlocalwifi].currentreachabilitystatus! =notreachable) {NSLog (@"is WiFi network"); }Else if([reachability reachabilityforinternetconnection].currentreachabilitystatus! =notreachable) {NSLog (@"It's a cellular network ."); }Else{NSLog (@"Network Failure"); }}

Long-term monitoring of network status

-(void) applymonitoring {    // Listener notification    object: nil];         // Start monitoring the network    self.reachability = [reachability reachabilityforinternetconnection];    [Self.reachability startnotifier];}

Cancel a task

-(void) dealloc{    [self.netreachability stopnotifier];     Object : nil];}
