Need Reachability version for ARC in iOS5 - wifi

Question

Using Apple's Reachability code in iOS5 I get a bunch of compilation errors as shown below. Any ideas on what is happening here? I'm using ARC so I have edited the standard code slightly to remove autorelease/retain and the NSAutoReleasePool.
Undefined symbols for architecture armv7:
"_SCNetworkReachabilityCreateWithAddress", referenced from:
+[Reachability reachabilityWithAddress:] in Reachability.o
"_SCNetworkReachabilityCreateWithName", referenced from:
+[Reachability reachabilityWithHostName:] in Reachability.o
"_SCNetworkReachabilityUnscheduleFromRunLoop", referenced from:
-[Reachability stopNotifier] in Reachability.o
"_SCNetworkReachabilityScheduleWithRunLoop", referenced from:
-[Reachability startNotifier] in Reachability.o
"_SCNetworkReachabilitySetCallback", referenced from:
-[Reachability startNotifier] in Reachability.o
"_SCNetworkReachabilityGetFlags", referenced from:
-[Reachability connectionRequired] in Reachability.o
-[Reachability currentReachabilityStatus] in Reachability.o
ld: symbol(s) not found for architecture armv7 clang: error: linker
command failed with exit code 1 (use -v to see invocation)
Does anyone have workable Reachability code for ARC under iOS5?

Answer 1

I wrote a clean 'drop in' version of reachability for ARC and iOS5 - you can get it here: https://github.com/tonymillion/Reachability

Answer 2

You don't really need an ARC version of Reachability, just simply disable ARC for reachability file(s)
Disable ARC on MULTIPLE files:
Select desired files at Target/Build Phases/Compile Sources in Xcode
PRESS ENTER
Type -fno-objc-arc
Press Enter or Done
You also have a missing framework. Add SystemConfiguration framework.

Answer 3

I rearranged them for IOS 5 and arc they are working tested
Please DON'T FORGET TO ADD SystemConfiguration.framework on your project

Answer 4

I just found this that might help. Thank the author for this (this is not mine)!

Answer 5

Apple's reachability has been updated to version 3 which now supports ARC iOS5+
Here is the link to the sample by Apple

Answer 6

You need to add the systemConfiguration.framework to make Reachability work.

Answer 7

I know this thread is old, but in case anyone is interested you can solve this by disabling ARC for Reachability.m. Look at this post.

Answer 8

Tony, is your class correctly work even with a non ARC project?
I can see lot ok Reachability: dealloc in my consolle, and I don't know if it's normal or not!
I use this method to check the connection (is the only place where I user Rechability)
-(BOOL)checkConnection{
BOOL connessione = FALSE;
Reachability *wifiResouce = [[Reachability reachabilityForLocalWiFi] retain];
Reachability *phoneResouce = [[Reachability reachabilityForInternetConnection] retain];
NetworkStatus netStatusWiFi = [wifiResouce currentReachabilityStatus];
NetworkStatus netStatusPhone = [phoneResouce currentReachabilityStatus];
if(netStatusWiFi == NotReachable){
if(netStatusPhone == ReachableViaWWAN){
connessione = TRUE;
}
}else if(netStatusWiFi == ReachableViaWiFi){
connessione = TRUE;
}
[phoneResouce release];
[wifiResouce release];
return connessione;
}
