实现cell的点击高亮

1：设置cell.selectionStyle = UITableViewCellSelectionStyleNone;

2：在cell的.m里实现重写

- (void)setHighlighted:(BOOL)highlighted animated:(BOOL)animated{//重写高亮函数
    if (highlighted)

- (void)setHighlighted:(BOOL)highlighted animated:(BOOL)animated{//重写高亮函数

    if (highlighted) {

        self.backgroundColor = [UIColorChange colorwithHexString:COLOROFLINE];

    }else{

        self.backgroundColor = [UIColor whiteColor];

    }

}
