好看的底线颜色： [UIColorcolorWithRed:70.0/255.0green:70.0/255.0blue:70.0/255.0alpha:1.0]

_addBottomMenuHairline 用于判断是否添加底边

    if (_addBottomMenuHairline) {        UIView *menuBottomHairline = [UIView new];                menuBottomHairline.translatesAutoresizingMaskIntoConstraints = NO;                [self.view addSubview:menuBottomHairline];                NSArray *menuBottomHairline_constraint_H = [NSLayoutConstraint constraintsWithVisualFormat:@"H:|[menuBottomHairline]|" options:0 metrics:nil views:@{@"menuBottomHairline":menuBottomHairline}];        NSString *menuBottomHairline_constraint_V_Format = [NSString stringWithFormat:@"V:|-%f-[menuBottomHairline(0.5)]",_menuHeight];        NSArray *menuBottomHairline_constraint_V = [NSLayoutConstraint constraintsWithVisualFormat:menuBottomHairline_constraint_V_Format options:0 metrics:nil views:@{@"menuBottomHairline":menuBottomHairline}];                [self.view addConstraints:menuBottomHairline_constraint_H];        [self.view addConstraints:menuBottomHairline_constraint_V];                menuBottomHairline.backgroundColor = _bottomMenuHairlineColor;    }
