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。
