Hi
I'm trying to implement reachability into my iPhone app to allow me to determine if the user has an internet connection. Unfortunately, I am getting two errors whilst trying to build the app. These are the steps I took to implement it:
I added the SystemConfiguration framework and added Reachability.h/.m to my classes folder.
I then added this to my viewcontroller.h file for the viewcontroller in which I am detecting an internet connection:
And then when I want to check if I am connected to the internet, I call this:
Unfortunately, when I build, I get the following two errors:
where the stuff in bold, underline and italics is the stuff in red in the error log, and hence the name of the bug.
I've no idea what's going on - something I've done wrong with my frameworks and architecture settings maybe?
Any help is much appreciated,
Thanks in advance,
Sam

I then added this to my viewcontroller.h file for the viewcontroller in which I am detecting an internet connection:
Code:
//Class.h
#import "Reachability.h"
#import <SystemConfiguration/SystemConfiguration.h>
- (BOOL)connected ;
Code:
In my .m file, I use this code as a boolean method, which when run will return if the user has an internet connection:
- (BOOL)connected
{
Reachability *reachability = [Reachability reachabilityForInternetConnection];
NetworkStatus networkStatus = [reachability currentReachabilityStatus];
return !(networkStatus == NotReachable);
}And then when I want to check if I am connected to the internet, I call this:
Code:
if(![self connected])
{
// not connected
} else
{
// connected, do some internet stuff
}
