    页面先 present 跳转到页面 2。这时候我写了一个 BUTTON 想要 push 到页面 3。发现 push 代码不工作，请问我要怎么做才能 push 出去

    （没用 storyboard，页面都是代码写的）

    NavigationController 都没了，肯定不能 push 啊。

    试试:
    1. 得到页面 2 的 presentingController
    2. 上面的 presentingController 获取 navigationController
    3. push
    不过, 感觉够呛, 即使能 push, 也是不合理.

    下确做法是, 页面 2 放到一个 UINavigationController 里, push 页面 3
