有人可以帮帮我吗？我在本网站上遇到了其他问题，并为 UITableViewDataSource 添加了所有必需的功能;

Can someone please help me? I have gone through other issues on this site and added all the required functions for "UITableViewDataSource";

import UIKit import Foundation class MyViewController: UIViewController, UITableViewDelegate, UITableViewDataSource { var array1:[String] = ["one","two","three","four"] var array2:[String] = ["IOS","Android","java","c++","Swift"] let sectionCount = 2 var myTableView:UITableView! // init(nibName nibNameOrNil: String?, bundle nibBundleOrNil: NSBundle?) { // var rect = CGRectMake(0, 0, 220, 320) // myTableView = UITableView(frame: rect, style: UITableViewStyle.Grouped) // super.init(nibName: nil, bundle: nil) // // Custom initialization // } override func viewDidLoad() { super.viewDidLoad() var rect = CGRectMake(0, 0, 320, 600) myTableView = UITableView(frame: rect, style: UITableViewStyle.Grouped) myTableView!.delegate = self myTableView!.dataSource = self self.view.addSubview(myTableView) } override func didReceiveMemoryWarning() { super.didReceiveMemoryWarning() // Dispose of any resources that can be recreated. } //dataSourrce //tableview：tableview，section： func tableView(tableView: UITableView!, numberOfRowsInSection section: Int) -> Int{ switch section{ case 0: return array1.count case 1: return array2.count default: return 1 } } func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell { //func tableView(tableView: UITableView!, cellForRowAtIndexPath indexPath: NSIndexPath!) -> UITableViewCell!{ //－－－cellstart－－－－ let identifier = "identifier" // var cell:UITableViewCell //cell var cell = tableView.dequeueReusableCellWithIdentifier(identifier) as?

推荐答案

您需要查看整个错误消息。此特定消息包含有关缺少哪些方法的其他信息：

You need to look at the whole error message. This specific message includes additional information about which methods are missing:

Type 'MyViewController' does not conform to protocol 'UITableViewDataSource' Protocol requires function 'tableView(_:numberOfRowsInSection:)' with type '(UITableView, numberOfRowsInSection: Int) -> Int' Candidate has non-matching type '(UITableView!, numberOfRowsInSection: Int) -> Int'

所以...你的numberOfRowsInSection需要一个可选的UITableView，并且应该带一个必需的UITableView（这个是他们在6和6.1之间进行的更改，所有UITableView委托和数据源方法现在都需要tableView和indexPath值）

So... your numberOfRowsInSection takes an optional UITableView, and should take a required UITableView (this is a change they made between 6 and 6.1, all UITableView delegate and datasource methods now take required tableView and indexPath values)
