swift hidesBottomBarWhenPushed 设置界面

方法一(推荐)：一级界面push的时候设置，子页面无需设置

            let vc = JYMyCommissionController()
            vc.hidesBottomBarWhenPushed = true
            self.navigationController?.pushViewController( vc, animated: true)

　　

方法二：设置两个界面，

1.
一级界面（rootViewController）

        self.hidesBottomBarWhenPushed = true

            self.navigationController?.pushViewController(JYMyCommissionController(), animated: true)
        self.hidesBottomBarWhenPushed = false

2.

二级界面
        self.hidesBottomBarWhenPushed = true

            self.navigationController?.pushViewController(JYMyCommissionController(), animated: true)
之后 所有子页面不需要设置了
