NSDocument writeToURL:, saving a simple html document

Im trying to implement a save feature to save an html file. Currently it returns errors when I try and save. My code is 

- (BOOL)writeToURL:(NSURL *)absoluteURL ofType:(NSString *)typeName error:(NSError **)outError
{
NSData *saveData = [[[editorView textStorage] string] dataUsingEncoding:NSUTF8StringEncoding];
[saveData writeToURL:absoluteURL ofType:typeName error:outError];

if ( outError != NULL ) {
    *outError = [NSError errorWithDomain:NSOSStatusErrorDomain code:unimpErr userInfo:NULL];
}
else {
    return YES;
}
}

When I try and save it returns the errors: -[NSConcreteMutableData writeToURL:ofType:error:]: unrecognized selector sent to instance 0x10016d900 -[NSConcreteMutableData writeToURL:ofType:error:]: unrecognized selector sent to instance 0x10016d900. I tired using a plain NSString and that didn't work either.

Thanks for any help

That's because an NSMutableData doesn't respond to that message. Only documents respond to that message.

You need to send your data object a message it does respond to, such as writeToURL:options:error:.
