ZLPhotoPreviewController 预览滚动时crash

[Aliffter]

Issue Description

Description and Steps

1. 从相册中选择图片，点击图片后预览，
2. 侧滑滚动预览照片crash。 必现 同样的代码及配置。另外一个项目就是正常的。然而我这个项目就回crash，必现 原因： 进入页面时，查看 self.navigationController 有值，滑动后 self.navigationController 不知何时为空了，导致强转crash resetSubViewStatus方法 ---> let nav = self.navigationController as! ZLImageNavController

crash如图：
