目前没有支持pod，主要是不会弄，执行注册cocoapodz命令一直失败
pod trunk register xxxx@qq.com 'xxx'

如何使用
var aniamtion: HSCoverVerticalTransition!
public init() {
super.init(nibName:nil, bundle:nil)
self.aniamtion = HSCoverVerticalTransition.init(present: self, dismiss: true)
self.transitioningDelegate = self.aniamtion
}
override func viewDidLoad() {
super.viewDidLoad()
self.preferredContentSize = CGSize.init(width: self.view.bounds.width, height: 450)
}

原理暂时就不讲了，网上有很多大神的文章，以后有时间可以整理补充
