Xcode，Swift，表格视图控制器

Question

我已经在情节提要上启动了一个Table View Controller和Designed Static Custom Cells，所以当我创建一个新的自定义swift文件（table view controller类）并添加到table view controller时，部署应用程序时，表部分消失了。

Answer 1

It seems that your problem is these delegates. They are provided in the template, and these will remove any static cells in this state. So if you are just using static cells, remove these functions, otherwise modify them to work with dynamic cells as well.

// MARK: - Table view data source

override func numberOfSections(in tableView: UITableView) -> Int {
    // #warning Incomplete implementation, return the number of sections
    return 0
}

override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    // #warning Incomplete implementation, return the number of rows
    return 0
}
