    UIBarButtonItem *btnItem = [UIBarButtonItem appearance];
    
    //  Set up current item Available status 
    NSMutableDictionary *normalAttr = [NSMutableDictionary dictionary];
    //  Set the foreground 
    normalAttr[NSForegroundColorAttributeName] = [UIColor orangeColor];
    //  Set current font size 
    normalAttr[NSFontAttributeName] = [UIFont systemFontOfSize:14];
    [btnItem setTitleTextAttributes:normalAttr forState:UIControlStateNormal];
    
    
    //  Set up current item Unavailable status
