現(xiàn)在這些框架很多第三方資源，但是想自己寫一個(gè)。側(cè)滑實(shí)現(xiàn)比較簡(jiǎn)單，根據(jù)自己需求去擴(kuò)展界面。
創(chuàng)建一個(gè)類MenuViewController作為Navigation的rootVC
新建一個(gè)UIView（MenuView）作為左側(cè)漏出來的一部分，新建一個(gè)ContentViewController作為右側(cè)可拖動(dòng)的部分。將兩個(gè)分別添加到MenuViewController上給ContentViewController的view加上拖拽的手勢(shì)。
實(shí)現(xiàn)手勢(shì)的事件方法，側(cè)滑效果就完成了。
