NSCocoaErrorDomain Code=256 "The operation couldn’t be completed. (Cocoa error 256.)

I'm getting the following error Error Domain=NSCocoaErrorDomain Code=256 "The operation couldn’t be completed. (Cocoa error 256.)" UserInfo=0x7febbb53b4f0 {NSURL=http://blog.teamtreehouse.com/api/get_recent_summary/} when i run my project with this code:

NSURL *blogURL = [NSURL URLWithString:@"http://blog.teamtreehouse.com/api/get_recent_summary/"];
NSError *error = nil;
NSData *jsonData = [NSData dataWithContentsOfURL:blogURL options:0 error:&error];
NSDictionary *dataDictionary = [NSJSONSerialization JSONObjectWithData:jsonData options:0 error: &error];
self.blogPost = [dataDictionary objectForKey:@"posts"];

Somebody can help me?

First of all, stick with dataWithContentsOfURL rather than adding options and error. Second of all, NSLog can't print error.
