reachability Detecting Network status

In the current project development, it is necessary to monitor whether the network is normal. reachability detection network can detect WiFi 3G wireless LAN

Using reachability

Download the reachability, add the reachability to the project, and add it to the class that will detect the network.

#import <Reachability.h>

Turn on network status monitoring

[[Nsnotificationcenter defaultcenter]addobserver:self selector: @selector (reachabilitychanged:) Name: Kreachabilitychangednotification Object:nil];

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

[Self.reachability startnotifier];//starts listening

In method reachabilitychanged: write about changing the network to do

Call method when network state changes

-(void) reachabilitychanged: (nsnotification *) Note

{

reachability *currreach = [Note Object];

Nsparameterassert ([Currreach iskindofclass:[reachability class]]);

Self.status = [Currreach currentreachabilitystatus];

self.isreachable = YES;

Switch (self.status) {

Case Notreachable:

{

Uialertview *alertview = [[Uialertview alloc]initwithtitle:@ ' network status ' message:@ ' Pro! No network! "Delegate:self cancelbuttontitle:@" Cancel "otherbuttontitles:@" OK ", nil];

[Alertview show];

self.isreachable = NO;

}

Break

Case Reachableviawifi:

{

Uialertview *alertview = [[Uialertview alloc]initwithtitle:@ ' network status ' message:@ ' connected wifi! "Delegate:self cancelbuttontitle:@" Cancel "otherbuttontitles:@" OK ", nil];

[Alertview show];

self.isreachable = YES;

}

Break

Case Reachableviawwan:

{

self.isreachable = YES;

}

Break

Default

Break

}

}

Can also be written directly in the appdelegate.
