    NSMutableAttributedString *one = [[NSMutableAttributedString alloc] initWithString:@"Shadow"];
    NSShadow *shadow = [[NSShadow alloc]init];
    shadow.shadowBlurRadius = 5;
    shadow.shadowOffset = CGSizeMake(0, 1);
    shadow.shadowColor = [UIColor colorWithWhite:0.000 alpha:0.490];
    [one addAttributes:@{NSShadowAttributeName:shadow,NSForegroundColorAttributeName:[UIColor whiteColor],NSFontAttributeName:[UIFont boldSystemFontOfSize:30]} range:NSMakeRange(0, 6)];
