If the editor is used with UIImagePickerController, try

- (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated
{
    if([navigationController isKindOfClass:[UIImagePickerController class]] && [viewController isKindOfClass:[CLImageEditor class]]){
        viewController.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemCancel target:self action:@selector(cancelButtonDidPush:)];
    }
}

- (void)cancelButtonDidPush:(id)sender
{
    [self.presentedViewController dismissViewControllerAnimated:YES completion:nil];
}
