AFNetworking-可达性始终返回-1

我使用最新的AFNetworking来源，可访问性对我而言不起作用，它从不触发可访问性块，并且 [httpClient networkReachabilityStatus] 始终返回-1。 .pch

I use latest AFNetworking sources and the reachability doesn't work for me, it never fires reachability block and the [httpClient networkReachabilityStatus] always returns -1. SystemConfiguration/SystemConfiguration.h is included in .pch

startMonitoringNetworkReachability已执行（在AFHTTPClient中）。

AFHTTPClient *httpClient = [AFHTTPClient clientWithBaseURL:[NSURL URLWithString:URL]];

[httpClient setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {

    NSLog(@"Internet status changed");
    NSLog(@"%d", status);
}];

NSMutableURLRequest *request = [httpClient requestWithMethod:@"POST" path:method parameters:post];

NSLog(@"Network reach %d",[httpClient networkReachabilityStatus]);

AFJSONRequestOperation *operation = [self getOperationWithMethod:method withRequest:request andCallback:callback];

[operation start];
