NSCocoaErrorDomain Code=256
cocoa, iphone, nsstring
Solution
Yes, the URL is missing the scheme: "http://".
"Error -> Error Domain=NSCocoaErrorDomain Code=256"
For the error code check the Apple documentation:
NSError codes in the Cocoa error domain.
NSFileReadUnknownError = 256,
`NSFileReadUnknownError` "Read error, reason unknown"
Not that the error definition is very helpful. :-)
Also do not check if `error` is `nil` to determine if there is an error, check the return value for `nil`. `error` is not guaranteed to be `nil` on successful execution.
Problem
I have been stuck with this for a while and don't seem to get around this. I am trying to read the contents of an URL as a string from an URL, But i get a weird Error -> Error Domain=NSCocoaErrorDomain Code=256 "The operation couldn’t be completed. (Cocoa error 256.)" My code : ``` fetchedString = [[NSString alloc] initWithContentsOfURL:[NSURL URLWithString:@"www.example.com/iphone"] encoding:NSUTF8StringEncoding error:&error]; NSLog(@"%@",fetchedString); // if there is something wrong with the URL if (error) { NSLog(@"Error -> %@", error); return ; } ``` What am I doing wrong? I tried using getting as NSData as well, but I get null back.
