AFNetworkReachabilityManager说没有网络 [英] AFNetworkReachabilityManager says no network

问题描述

由于缺少示例，我很困惑，所以我在appDelegate的didFinishLaunching中做了这个：

I'm confused due to lack of examples, so I did this in my appDelegate's didFinishLaunching:

[[AFNetworkReachabilityManager sharedManager] startMonitoring];
bool isThere = [[AFNetworkReachabilityManager sharedManager] isReachable];

尽管网络在那里工作，但总是返回false。

And that always returns false, in spite of the network being there and working.

两个问题：

1）如果我不是在寻找状态变化，我是否需要startMonitoring？

1) if I'm not looking for changes in status, do I need startMonitoring?

2）在阅读isReachable之前你需要做些什么吗？你需要等待吗？

2) is there anything you need to do before reading isReachable? Do you need to wait?

推荐答案

我知道现在回答为时已晚。如果有人在寻找这个。

I know it's too late to answer. If anybody looking for this.

确定网络状态只需要很少的时间。
因此，在startMonitoring之后立即调用 isReachable 将始终返回 false 。

Determining network status requires little time. So, calling isReachable right after startMonitoring will always return false.

您可以致电 isReachable 在 setReachabilityStatusChangeBlock ;

    [[AFNetworkReachabilityManager sharedManager] startMonitoring];
    [[AFNetworkReachabilityManager sharedManager] setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status){
          NSLog(@"status changed");
         //check for isReachable here
    }];
