Can I add the Do not Back up for the “Document Directory” for iCloud

Question

I had read that I can mark folders with \"do not backup\" attribute with ios 5.1 and later

As i understand, in such case all contents of directory will be excluded f

From the Apple docs, for iOS 5.1 or later, you should use this:

- (BOOL)addSkipBackupAttributeToItemAtURL:(NSURL *)URL
{
    assert([[NSFileManager defaultManager] fileExistsAtPath: [URL path]]);

    NSError *error = nil;
    BOOL success = [URL setResourceValue: [NSNumber numberWithBool: YES]
                                  forKey: NSURLIsExcludedFromBackupKey error: &error];
    if(!success){
        NSLog(@"Error excluding %@ from backup %@", [URL lastPathComponent], error);
    }
    return success;
}
