NSData return nil when parse html

Question

I want to get some information from this website "http://phim14.net/". I use this code :

NSURL *url = [NSURL URLWithString:@"http://phim14.net/"];
     NSError *error;
     NSData *htmlData = [NSData dataWithContentsOfURL:url options:NSDataReadingUncached error:&error];
     TFHpple *parser = [TFHpple hppleWithHTMLData:htmlData];

At the beginning this code is working and I can get some info. But after several times trying I met an error that "htmlData" was return nil, so I think the website was down but I can connect to that webpage using Firefox. I try to parse other website but it's still ok? I try to print out the error and it said that

`"error NSError *   domain: @"NSCocoaErrorDomain" - code: 256   0x00007fbb224023c0"`

Someone please help me figure out what is the problem??

It seems errorcode 256 doesn't have much description. So for safe way to get data from URL, use this method sendSynchronousRequest:returningResponse:error: from NSURLConnection.

NSData* data = [NSURLConnection sendSynchronousRequest:[NSURLRequest requestWithURL:url cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:30] returningResponse:nil error:&error];

Also please check these answer1, answer2

Your URL is missing the scheme: "http://" and this is giving you the error:

Error -> Error Domain=NSCocoaErrorDomain Code=256

Try adding this to the URL and it should work.
