Several methods of ios-network detection

1.AFN in the frame: Afnetworkreachabilitymanager

AFN Judging the network

-(void) getinternetstatue{

1. Managers who have access to network monitoring

Afnetworkreachabilitymanager *mgr = [Afnetworkreachabilitymanagersharedmanager];

2. Set up the processing after the network status change

[Mgr setreachabilitystatuschangeblock:^ (afnetworkreachabilitystatusstatus) {

When the network state changes, the block is called

Switch (status) {

caseafnetworkreachabilitystatusunknown://Unknown Network

NSLog (@ "Unknown network");

Break

caseafnetworkreachabilitystatusnotreachable://No network (off-grid)

NSLog (@ "No network (off-Grid)");

Break

caseafnetworkreachabilitystatusreachableviawwan://mobile phone comes with network

NSLog (@ "Mobile phone comes with network");

Break

caseafnetworkreachabilitystatusreachableviawifi://WIFI

NSLog (@ "WIFI");

Break

}

if (Status ==afnetworkreachabilitystatusreachableviawwan | | status ==afnetworkreachabilitystatusreachableviawifi)

{

[Email protected] "network";

NSLog (@ "NET");

}else

{

[Email protected] "no network";

NSLog (@ "no net");

Uialertview *alert = [[uialertviewalloc]initwithtitle:@] network loses connection "message:nildelegate:selfcancelbuttontitle:@" Cancel " Otherbuttontitles:nil,nil];

Alert.delegate =self;

[Alert show];

}

}];

3. Start monitoring

[Mgr Startmonitoring];

}

========= 2. Apple comes with reachability =========

1. Enumeration representing the state of the network:

typedef enum:nsinteger {    notreachable = 0,//no network available    Reachableviawifi,//wifi connection    Reachableviawwan//Unlimited WAN connection} NetworkStatus;
2, the following is the relevant interface and comments

/*! * To detect if a network request can reach the specified hostname */+ (instancetype) Reachabilitywithhostname: (NSString *) hostname;/*! * To detect if a network request can reach the given IP address */+ (instancetype) reachabilitywithaddress: (const struct sockaddr_in *) hostaddress;/*! * Check if the default router is valid. For apps that aren't connected to a specific host. */+ (instancetype) reachabilityforinternetconnection;/*! * Detects if the local WiFi connection is valid */+ (instancetype) reachabilityforlocalwifi;/*! * Start listening for notifications in the current runloop. */-(BOOL) startnotifier;-(void) stopnotifier;//Get network Status-(NetworkStatus) currentreachabilitystatus;/*! * Connection Requirement */-(BOOL) connectionrequired;

3. Notification identification when the network connection status changes

NSString *kreachabilitychangednotification = @ "Knetworkreachabilitychangednotification";

You need to copy the Reachability.h and REACHABILITY.M from the project to your project, and you need to add systemconfiguration.framework to the project,

Create reachability

reachability *reach = [reachability reachabilityforinternetconnection];

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

Start monitoring the network (notify Kreachabilitychangednotification once the network status changes)

[Reach Startnotifier];

Turn on notification---way one:

[[Nsnotificationcenter Defaultcenter] addobserver:self selector: @selector (networkstatechange:) Name: Kreachabilitychangednotification Object:nil];

Handling Network status changes

-(void) Networkstatechange: (nsnotification *) note{

reachability * reach = [Noti object];

NetworkStatus status = [reach Currentreachabilitystatus];

3. Determine network status

if (status== notreachable) {

NSLog (@ "no net");

} else if (Status==reachableviawwan) {

NSLog (@ "Use your phone to bring your own network to the Internet");

} else if (Status==reachableviawifi) {

NSLog (@ "via wifi");

}}

Registration Notice----WAY two:

[[Nsnotificationcenter Defaultcenter] Addobserver:self

Selector: @selector (reachabilitychanged:)

Name:kreachabilitychangednotification

object:nil];//Network Status Monitoring

-(void) reachabilitychanged: (nsnotification *) Noti {

reachability * reach = [Noti object];

if ([reach isreachable]) {

[Self setmbprogresswithnumtip:@ "network Connected"];

NSLog (@ "Network is connected");

[Lycommanmanager sharedmanager].isreachable=[reachisreachable];

[[nsnotificationcenterdefaultcenter]postnotificationname:@ "startloading" object:nil];//send notification start loading web page

} else {

NSLog (@ "Network not Connected");

[Self setmbprogresswithnumtip:@ "network not Connected"];

[Lycommanmanager sharedmanager].isreachable=[reachisreachable];

[[nsnotificationcenterdefaultcenter]postnotificationname:@ "endloading" object:nil];//send notification end load

}

}

-(void) viewdidoad{

if ([Lycommanmanager sharedmanager].isreachable) {

[Self setmbprogresswithnum:@ "Loading ..."];

NSLog (@ "Currently there is a network de");

}else {

[Self setmbprogresswithnumtip:@ "no network Connection"];

NSLog (@ "currently no Network");

}

[[Nsnotificationcenter Defaultcenter]addobserver:selfselector: @selector (finishloading) name:@ "Endloading" object: NIL];

[[Nsnotificationcenter Defaultcenter]addobserver:selfselector: @selector (startloading) name:@ "StartLoading" Object : nil];

}

Re-load Web pages after networking

-(void) startloading{

[Self settrainticketwithmkweb];

}

End Load Prompt

-(void) finishloading{

[Mbprogresshud HideHUDForView:self.view Animated:yes];

}

=========3. Judging the network ========= through the status bar

To get the network type from the status bar, the code is as follows:

-(NSString *) getnetworkstates{

UIApplication *app = [Uiapplicationsharedapplication];

Nsarray *children = [[[appvalueforkeypath:@ "StatusBar"]valueforkeypath:@ "Foregroundview"]subviews];

NSLog (@ "---%@---", children);

NSString *state = [[Nsstringalloc]init];

NSLog (@ "--empty string 0-%@", state);

int netType = 0;

Get to the network return code

For (ID Childin children) {

if ([Childiskindofclass:nsclassfromstring (@ "Uistatusbardatanetworkitemview")]) {

Get to status bar

NetType = [[Child valueforkeypath:@ "Datanetworktype"]intvalue];

NSLog (@ "NetType---%d", netType);

Switch (netType) {

Case 0:

state = @ "No network";

No network mode

Break

Case 1:

State = @ "2G";

Break

Case 2:

State = @ "3G";

Break

Case 3:

State = @ "4G";

Break

Case 5:

{

state = @ "WiFi";

NSLog (@ "5");

Break

Default

Break

}

}

}

Select by Status

}

return state;

}
