iphone - mapViewDidFailLoadingMap delegate method gets called with error == 0 -

-

In my view controller, I create an MKMapView object. I set myself a delegate, and in ViewController, I implemented: 

  - (zero) mapViewDidFailLoadingMap: (MKMapView *) mapView withError: (NSError *) error

This method is called, but in Debugger, I think the value in error is 0x0

It is on the device, and in the simulator.

I need an error code because I want to give a message for the case where Internet access is unavailable, while ignoring cases (from the API doctor) "if an additional map for tile The request comes when the last request of the tile is still pending "(which does not seem like a failure)

< P> I did some tests

  1. Internet is off: [error description] = error Domain = NSURLErrorDomain code = -1009 User Interface = 0x46c6120 "No Internet Connection"
  2. Scroll around very quickly: Error = zero (0x0)

I know There is no other error situation, but at least you can discriminate between an Internet connection error (in which I will show a warning) and scrolling the case very quickly, in which I will ignore it.

Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI). And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes.
