使用blocks 方法监听，当网络状态变化时，blocks会调用两次

[zhufengyi01]

我是使用cocoapod导入的 ：pod "Reachability",'~>3.2' 我在didFinishLaunchingWithOptions方法中使用这个 Reachability* reach = [Reachability reachabilityWithHostname:@"www.baidu.com"];

// Set the blocks
reach.reachableBlock = ^(Reachability*reach)
{
    // keep in mind this is called on a background thread
    // and if you are updating the UI it needs to happen
    // on the main thread, like this:

    dispatch_async(dispatch_get_main_queue(), ^{
        NSLog(@"网络可用了");
    });
};

reach.unreachableBlock = ^(Reachability*reach)
{
    NSLog(@"网络连接失败了!");
};

// Start the notifier, which will cause the reachability object to retain itself!
[reach startNotifier];

当网络状态变化时，会调用两次blocks

reach 初始化了两遍， 所以调用了两次 ~

我也遇到了这个问题,但是应该没有初始化两次,很奇怪
