我如何使用视图控制器制作 table 视图 swift

Question

我可以制作一个具有 table 视图的应用程序，但我需要单元格将我重定向到 YouTube 视频。我想在按下一个单元格时显示一个 youtube 视频或将我发送到另一个视图控制器。请帮助我

 class ViewController: UITableViewController {


var tricks = [Trick]()



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


    self.tricks = [Trick(name: "Ollie" ), Trick(name: "Kickflip"), Trick(name: "Heelflip"), Trick(name: "Varial Kickflip"), Trick(name: "Varial Heelflip"), Trick(name: "TreeFlip")]




}

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


override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) ->Int {

    return self.tricks.count
}

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cell = self.tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath)as! UITableViewCell

    var trick : Trick

    trick = tricks[indexPath.row]

    cell.textLabel?.text = trick.name

    return cell

}

}

Answer 1

尝试为 did select cell

实现委托方法

func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
    tableView.deselectRowAtIndexPath(indexPath, animated: true)

    let trick = tricks[indexPath.row]
    //Now you have you selected trick so push in a your video playing view controller with the url from your trick object

}

我觉得对你有帮助。

func selectRow() -> Tricks? {
    let selectedRow = self.tableView.selectedRow;
    if selectedRow > 0 && selectedRow < self.tricks.count {
        selectedRow.description
        return self.tricks[selectedRow]
    }
    return nil
}

extension MasterViewController: NSTableViewDelegate {
    func tableViewSelectionDidChange(notification: NSNotification) {
        updateDetailInfo(selectedRow())
    }
}

Answer 3

我想你会想要制作另一个带有网络视图的视图控制器。然后，每当您 select table 中的一个单元格时，转到它并传递一个字符串，例如视频的 URL。

var tricks = ["Ollie", "Kickflip", "Heelflip", "Varial Kickflip", "Varial Heelflip"]
var selectedRow = 0


//SELECT THE ROW  & Call THE SEGUE
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
  tableView.deselectRowAtIndexPath(indexPath, animated: true)

  selectedRow = indexPath.row
  self.performSegueWithIdentifier("myVideoSegue", sender: self)

}

//PASS THE DATE TO THE NEXT VIEW CONTROLLER
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
  if (segue.identifier == "myVideoSegue") {

    let nextVC = segue.destinationViewController as ViewController;
    nextVC.passedTrickName = tricks[selectedRow]
  }
}
