Swift基础－－使用TableViewController自定义列表

首先建立一个swift项目，把storyboard的内容删掉，添加一个 Navigation Controller，然后设置storyboard对应界面的class，在Navigation Controller界面设置View Controller的is initial View Controller，这里使用的自定义列表内容，所以要新建一个继承UITableViewCell的类，然后设置storyboard中Table View的Prototype Cells的class，对于点击item进入详情界面，使用TableView 中的prepareForSegue方法。
