'HomePageVCNEW' 对协议(protocol) 'UITableViewDelegate' 的快速冗余一致性

Question

它给出了一个错误 UITableViewDataSource, UITableViewDelegate

“HomePageVCNEW”与协议(protocol)“UITableViewDelegate”的冗余一致性

import UIKit

当一个类继承自 UITableViewController 时，它默认符合 UITableViewDataSource 和 UITableViewDelegate，您无需指定它。尝试在 UITableViewController

之后删除 UITableViewDataSource 和 UITableViewDelegate
