swift4 滑动菜单，每一个被滑动的页面都是一个VC。
如果想用每一个滑动页面是View的话，可以使用另一个sdk——ScrollMenusView，地址是：
https://github.com/weiman152/ScrollMenusView
支持cocoa pods
platform :ios, '9.0' inhibit_all_warnings!
target '你的项目名字' do use_frameworks!
pod ScrollMenusViewController
end
如果想了解实现思路，请参考： https://www.jianshu.com/p/6be966481899 以及 https://www.jianshu.com/p/3ef5575fb6f7

switch index % 3 {
case 0:
vc = ChildListViewController.instance(index: index)
case 1:
vc = ChildImageViewController.instance(index: index)
case 2:
vc = ChildTextViewController.instance(index: index)
default: break
}
viewController.addChildViewController(vc)
viewController.view.addSubview(vc.view)
vc.view.frame = viewController.view.bounds
}
}
