我有三个数组。一个显示 tableView 上每个部分的标题，一个显示标题，一个显示每个单元格的链接。当我运行此代码时，我得到：
无法使用“IndexPath”类型的索引为“[Array]”类型的值下标
此错误出现在这一行：
viewController.websiteURL = links[myIndex]
我的 firstViewController 代码是：
import UIKit
class FirstViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {
var headers = ["Bein Sports", "Sky Sports", "Alkass", "Other"]
var channels = [["Bein Sports 1","Bein Sports 2","Bein Sports 3","Bein Sports 4","Bein Sports 5","Bein Sports 6","Bein Sports 7","Bein Sports 8","Bein Sports 9","Bein Sports 10","Bein Sports News"],
["Sky Sports 1","Sky Sports 2","Sky Sports 3","Sky Sports 4","Sky Sports 5"],
["Alkass One", "Alkass Two", "Alkass Three", "Alkass Four", "Alkass Five"],
["BT Sports 1", "BT Sports 2", "Real Madrid TV", "Real Madrid TV 2"]]
var links = [["https://www.google.ca","https://www.facebook.com","https://facebook.com","https://facebook.com","https://facebook.com","https://facebook.com","https://facebook.com","https://facebook.com","https://facebook.com","https://facebook.com","https://facebook.com"],

["http://twitter.com","http://facebook.com","http://www.google.com","http://www.instagram.com"]]
var myIndex : IndexPath = IndexPath()
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return channels[section].count
}
func numberOfSections(in tableView: UITableView) -> Int {
return channels.count //Rows
}
func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
return headers[section] //Sections
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath)
cell.textLabel?.text = channels[indexPath.section][indexPath.row] //TextLabel
return cell
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
myIndex = NSIndexPath(row: indexPath.section, section: indexPath.row) as IndexPath
performSegue(withIdentifier: "segue", sender: self)
}
func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?)
{
if (segue.identifier == "segue") {
let viewController = segue.destination as! ChannelViewController
// Now you have a pointer to the child view controller.
// You can save the reference to it, or pass data to it.
viewController.websiteURL = links[myIndex]
}
}
