ios - 尽管网络连接，AFNetworking仍未返回任何连接

Question

我正在使用AFNetworking来确定用户是否具有Internet连接。在wifi和4G LTE上均返回false，我已经检查以确保它们可以正常工作。
我有以下代码:

-(void)viewDidLoad{
 [[AFNetworkReachabilityManager sharedManager] startMonitoring];   

     if ([self connected])
        [self doSomething];
     else
        [self noConnection];
}

- (BOOL)connected {
     NSLog(@"This returns 0 %hhd", [AFNetworkReachabilityManager sharedManager].reachable);
     return [AFNetworkReachabilityManager sharedManager].reachable;
}

-(void)noConnection{
    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"No Internet!"
                                                message:@"Sorry, but you don't have an internet      connection at this time.  Please try again later."
                                               delegate:self
                                      cancelButtonTitle:@"OK"
                                      otherButtonTitles:nil];
     [alert show];

 }

Answer 1

这不是使用AFNetworking的解决方案，而是使用sample code from apple

一旦有了downloaded并导入了Reachbility.m和Reachbility.h文件

创建一个辅助函数:

-(BOOL)isConnected{
  Reachability *reachability = [Reachability reachabilityForInternetConnection];
  NetworkStatus networkStatus = [reachability currentReachabilityStatus];

  return !(networkStatus == NotReachable);    
}

然后用

if([self isConnected]){
 //connected!
}
else{
  //not connected to internet!
}

非常重要
