How to set font & color of the title in UINavigationBar using iOS5 appearance API?

Question

I have a multiple View Controllers and I want to set the font color of all to red.

 [[UINavigationBar appearance] setFont:[UIFont boldSystemFontOfSize:12.0]]

This could be used to set a custom view to a single navigationBar instead of a global setting

- (void)updateTitleWithString:(NSString *)title
{
    UIView *headerView = [[UIView alloc] initWithFrame:CGRectZero];
    [headerView setAutoresizingMask:UIViewAutoresizingFlexibleWidth];
    [headerView setAutoresizesSubviews:YES];

    CGFloat headFontSize = (IS_SYSTEM_DEVICE_IPAD ? 25.0f : 19.0f);
    UIFont *headFont = [UIFont boldSystemFontOfSize: headFontSize ];

    NSMutableParagraphStyle *style = [[NSParagraphStyle defaultParagraphStyle] mutableCopy];
    [style setLineBreakMode:NSLineBreakByTruncatingTail];

    CGSize size = [title boundingRectWithSize:CGSizeMake(190,headFontSize + 6) options:NSStringDrawingUsesLineFragmentOrigin
                                   attributes:@{NSFontAttributeName : headFont, NSParagraphStyleAttributeName : style} context:nil].size;

    headerView.frame  = CGRectMake(0, 0,size.width,self.navigationController.navigationBar.frame.size.height);
    float labelHeight = headFontSize + 6;
    float labelYLoc   = (   self.navigationController.navigationBar.frame.size.height - labelHeight ) / 2;
    UILabel *label    = [[UILabel alloc] initWithFrame:CGRectMake(0,labelYLoc, size.width,labelHeight)];
    label.backgroundColor = [UIColor clearColor];
    label.adjustsFontSizeToFitWidth = YES;
    label.textAlignment = NSTextAlignmentCenter;
    label.textColor = [UIColor whiteColor];
    label.font = headFont;
    label.text = title;
    label.shadowColor = [UIColor colorWithWhite:0.0 alpha:0.4];
    label.lineBreakMode = NSLineBreakByTruncatingTail;
    label.shadowOffset = CGSizeMake(0,-1);
    label.accessibilityLabel = @"";
    [headerView addSubview:label];

    self.navigationItem.titleView = headerView;
}
