类型'ViewController'不符合协议'UITableViewDataSource' [英] Type 'ViewController' does not conform to protocol 'UITableViewDataSource'

问题描述

开始练习快速。在singleViewController中，我试图创建一个 UITableView 。在storyboard中我设置了数据源和委托。这里我收到错误 *'ViewController'不符合协议'UITableViewDataSource'*

Started practice swift. In singleViewController I am trying to make a UITableView. In storyboard I set the datasource and delegate. Here I am getting the error * 'ViewController' does not conform to protocol 'UITableViewDataSource' *

class ViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {
    @IBOutlet weak var table: UITableView!


    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }


}

func numberOfSectionsInTableView(tableView: UITableView!) -> Int
{
    return 20
}
func tableView(tableView: UITableView!, cellForRowAtIndexPath indexPath: NSIndexPath!) -> UITableViewCell!
{
    let cell:UITableViewCell=UITableViewCell(style: UITableViewCellStyle.Subtitle, reuseIdentifier: "mycell")
cell.textLabel.text="row#\(indexPath.row)"
    cell.detailTextLabel.text="subtitle#\(indexPath.row)"

    return cell

}

推荐答案

您应该在最后一个} ，但是你已经在UIViewController之外写了它们。此外，您需要更改行数的func。

You should implement all the required methods before the last }, but you have written them outside of the UIViewController. Also, you need to change the func for number of lines.

class ViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {
    @IBOutlet weak var table: UITableView!


    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    func tableView(tableView:UITableView!, numberOfRowsInSection section:Int) -> Int
    {
        return 20
    }

    func tableView(tableView: UITableView!, cellForRowAtIndexPath indexPath: NSIndexPath!) -> UITableViewCell!
    {
        let cell:UITableViewCell=UITableViewCell(style: UITableViewCellStyle.Subtitle, reuseIdentifier: "mycell")
        cell.textLabel.text="row#\(indexPath.row)"
        cell.detailTextLabel.text="subtitle#\(indexPath.row)"

        return cell
    }
}
