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];
