推荐答案

这是绝对正确的。

它将触发 kReachabilityChangedNotification 通知，告知您新的可达性状态。

It will fire off a kReachabilityChangedNotification notification that tells you the new reachability state.

你得到的新的可达性状态如下：

You get the new reachability state something like this :

- (void)reachabilityChanged:(NSNotification *)notification {
    Reachability *reachability = notification.object;

    if (NotReachable == reachability.currentReachabilityStatus)
        NSLog(@"No longer reachable");
}
