I understand how I can test internet reachability in my app, but what i need to do is constantly listen for reachability, app wide. So if any point anywhere in the app the connection status changes, I can react.
How would I achieve something like this?
You need to add an observer for reachability change notification :
Firstly import in your class: #import "Reachability.h"
then add observer :
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(reachabilityChanged:)
name:kReachabilityChangedNotification
object:nil];
-(BOOL)reachabilityChanged:(NSNotification*)note
{
BOOL status =YES;
NSLog(@"reachabilityChanged");
Reachability * reach = [note object];
if([reach isReachable])
{
//notificationLabel.text = @"Notification Says Reachable"
status = YES;
NSLog(@"NetWork is Available");
}
else
{
status = NO;
UIAlertView *alert=[[UIAlertView alloc]initWithTitle:@"You are not connected to the internet" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
[alert show];
}
return status;
}
