可达性无法按预期工作 [英] Reachability not working as expected

问题描述

从Apple下载Reachability，使用此方法检查活动连接：

Downloaded Reachability from Apple, using this method to check for an active connection:

-(BOOL)isReachable{

    Reachability *r = [Reachability reachabilityWithHostName:@"http://www.google.com"];

    if(NotReachable == [r currentReachabilityStatus]) {
        NSLog(@"Not Reachable");
        return NO;
    }

    NSLog(@"Reachable");
    return YES;  

}

尽管已连接，但每次都返回NO？无法弄清楚为什么......

Returns NO every single time despite being connected? Can't figure out why...

任何想法？谢谢。

在附注中，有人可以推荐一个干净的Reachability单例类吗？

On a side note, can anyone recommend a good clean Reachability singleton class?

推荐答案

已编辑：您应从 reachabilityWithHostName http c>调用，将其更新为

EDITED: you should remove the protocol, http from your reachabilityWithHostName call, so updated it to

 Reachability *reachability = [Reachability reachabilityWithHostname:@"www.google.com"];
 NetworkStatus netStatus = [reachability currentReachabilityStatus];
