Best way to implement RKReachabilityObserver in RestKit

Question

I have written a tab based application in Xcode/RestKit and am attempting to use the RKReachabilityObserver to determine Internet connectivity on the device.

Ideally

Answer 1

Here is some changes in RestKit 0.20 and later. The code of reachability block should looks like:

    RKObjectManager *manager = [RKObjectManager managerWithBaseURL:[RemoteTools serverUrl]];
[manager.HTTPClient setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {
    if (status == AFNetworkReachabilityStatusNotReachable) {
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"No network connection"
                                                        message:@"You must be connected to the internet to use this app."
                                                       delegate:nil
                                              cancelButtonTitle:@"OK"
                                              otherButtonTitles:nil];
        [alert show];
    }
}];

Answer 2

The [RKClient sharedClient] singleton already has a property for that (reachabilityObserver). Feel free to use that one.

if ([[[RKClient sharedClient] reachabilityObserver] isReachabilityDetermined] && [[RKClient sharedClient] isNetworkReachable]) {
    ....
}

You can also subscribe to RKReachabilityObserver notifications (if you want to take any action when reachability status changes)

    [[NSNotificationCenter defaultCenter] addObserver:self 
                                             selector:@selector(reachabilityStatusChanged:) 
                                                 name:RKReachabilityDidChangeNotification object:nil];
