iOS : Connected to wifi but no internet access

Question

我已启用我的移动数据 (3G/4G)，但我的移动网络中没有剩余数据。

是否有可能快速知道上述条件。

我检查了下面的代码，但它给了我错误的信息。以下条件仅在关闭移动数据时满足。我的要求是移动数据打开并且没有可用的互联网

    let reachability = Reachability(hostName: "https://www.google.com")
    if reachability.currentReachabilityStatus() == NotReachable {

    }

找到适合我的解决方案

func isConnectedToNetwork()->Bool {
    var Status:Bool = false
    let url = NSURL(string: "http://google.com/")
    let request = NSMutableURLRequest(URL: url!)
    request.HTTPMethod = "HEAD"
    request.cachePolicy = NSURLRequestCachePolicy.ReloadIgnoringLocalAndRemoteCacheData
    request.timeoutInterval = 10.0
    var response: NSURLResponse?
    _ = try? NSURLConnection.sendSynchronousRequest(request, returningResponse: &response) as NSData?
    if let httpResponse = response as? NSHTTPURLResponse {
        if httpResponse.statusCode == 200 {
            Status = true
        }
    }
    return Status
}
