Errata Chapter 5: Handling Errors

Hello,

Thank you for the great book. It is a pleasure to read and an awesome source for all aspects of iOS network programming.

I might be wrong but in the "networkChanged" method on page 100 a Reachability object is directly compared with a NetworkStatus value.
For my understanding the method should better read:

Code:

- (void)networkChanged:(NSNotification*)notification {
    Reachability *reachability = [notification object];
    NetworkStatus status = [reachability currentReachabilityStatus];
    
    if (status == ReachableViaWWAN) {
        // Reachable vie WWAN
    }
    ...

Cheers,

Foxtrott,

You are correct. The example in that section does contain a defect that it is not reading the correct property to properly ascertain the network status.

Sorry for the mistake.
