plist文件 1、直接拖拽一个UITableViewController控件 删除原有的View，以及相应的ViewController类，直接拖拽一个UITableViewController控件，并将其对应的类设置为FRTableViewController，这个类自动指定了UITableViewDatoSource和UITableViewDelegate协议通过继承UITableViewController来实现，而UITableViewController已经指定了这两个协议），此外，还自动指定了一个tableView的类属性，因此不再需要通过拖线的方式来指定tableView这个属性。
