推荐答案

这是一个同步的例子。您可能希望异步执行此操作，但这将帮助您快速检查。

Here's a synchronous example. You'll probably want to do this asynchronously, but this will get you through for a quick check.

Reachability *netReach = [Reachability reachabilityWithHostName:@"host.name"];
//return [netReach currentReachabilityStatus];
NetworkStatus netStatus = [netReach currentReachabilityStatus];
if (netStatus==ReachableViaWiFi) {
    [ViewManager showStatus:@"Reachable (WiFi)!"];
} else if(netStatus==ReachableViaWWAN) {
    [ViewManager showStatus:@"Reachable (WWAN)!"];
} else {
    [ViewManager showStatus:@"Not reachable, aww :-("];
}

使用reachabilityWithHostName时，你必须记住这只是主机名，不应该有http：//前缀等。

When using reachabilityWithHostName you have to remember that this is just the host name, there should be no http:// prefix or the like.
