Ios 将数据与分段一起传递

问题是：我试图将一些数据从一个ViewController传递到另一个InfoViewController。看起来是这样的：

运行，应用程序，它看起来像这样：

除了这两个视图控制器之外，我在这个应用程序中还有一些其他的视图控制器，它们的序列工作得很好，但是，当我点击单元格时，它确实会转到InfoViewController，但信息不会得到更新

这是我的密码：

import UIKit import CoreData

protocol sendNameDelegate {
    func sendName(name: String) }

protocol sendImageDelegate {
    func sendImage(image: UIImage) }

class MainViewController: UIViewController, UITableViewDataSource, UITableViewDelegate, sendDetailsToMVCDelegate, NSFetchedResultsControllerDelegate, NSCoding {

    @IBOutlet weak var tableView: UITableView!
    var namesListArray:[String] = []
    var imagesListArray:[UIImage] = []
    var delegateName: sendNameDelegate?
    var delegateImage: sendImageDelegate?

    required init(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
        if let namesList = aDecoder.decodeObjectForKey("namesListArray") as? [String] {
            namesListArray = namesList
        } else {
            namesListArray = [String]()
        }
        if let imagesList = aDecoder.decodeObjectForKey("imagesListArray") as? [UIImage] {
            imagesListArray = imagesList
        } else {
            imagesListArray = [UIImage]()
        }
    }

    override func encodeWithCoder(aCoder: NSCoder) {
        aCoder.encodeObject(self.namesListArray, forKey: "namesListArray")
        aCoder.encodeObject(self.imagesListArray, forKey: "imagesListArray")
    }

    override func viewDidLoad() {
        let dir = getUserDir()
        let archiveName = "\(dir)/iRecipeList-namesListArray"
        if let loaded: AnyObject = NSKeyedUnarchiver.unarchiveObjectWithFile(archiveName) {
            self.namesListArray = (loaded as? [String])!
        }
        let archiveImage = "\(dir)/iRecipeList-imagesListArray"
        if let loaded: AnyObject = NSKeyedUnarchiver.unarchiveObjectWithFile(archiveImage) {
            self.imagesListArray = (loaded as? [UIImage])!
        }
    }

    override func viewDidAppear(animated: Bool) {
    }

    func sendDetailsToMVC (name: String, image: UIImage) {
        namesListArray.append(name)
        imagesListArray.append(image)
        let dir = getUserDir()
        let archiveName = "\(dir)/iRecipeList-namesListArray"
        NSKeyedArchiver.archiveRootObject(namesListArray, toFile: archiveName)
        let archiveImage = "\(dir)/iRecipeList-imagesListArray"
        NSKeyedArchiver.archiveRootObject(imagesListArray, toFile: archiveImage)
        tableView.reloadData()
    }

    func getUserDir() -> String {
        let userDir = NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.DocumentDirectory, NSSearchPathDomainMask.UserDomainMask, true)
        return userDir[0] as! String
    }


    func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return namesListArray.count
    }

    func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
        let row = indexPath.row
        let name = namesListArray[row]
        println("\(row)/")
        let image = imagesListArray[row]
        var cell = UITableViewCell(style: UITableViewCellStyle.Default, reuseIdentifier: nil)
        cell.textLabel?.text = name
        cell.imageView!.image = image

        return cell }

    func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {

        var row = indexPath.row

        var name = namesListArray[row]
        delegateName?.sendName(name)
        var image = imagesListArray[row]
        delegateImage?.sendImage(image)

        performSegueWithIdentifier("goToInfoVC", sender: self)
    }

    override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
        if segue.identifier == "newReciep" {
            var vc = segue.destinationViewController as! DetailsViewController
            vc.delegateDetails = self
        }
    } }

以及：

我似乎无法正确地将此信息发送到最后一个视图控制器。有人有什么想法吗

PS：很抱歉图像太多，我想这会很有帮助。

您当前正在调用sendName和sendImage代理，然后再为它们赋值。这就是他们无法访问您的InformationViewController的原因。你应该这样做：

    override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
        if segue.identifier == "newReciep" {
            var vc = segue.destinationViewController as! DetailsViewController
            vc.delegateDetails = self
        }else if(segue.identifier == "goToInfoVC"){
            var vc = segue.destinationViewController as! InformationViewController

            let row = self.tableView.indexPathForSelectedRow()?.row
            var name = namesListArray[row]
            var image = imagesListArray[row]
            vc.name = name
            vc.image = image

        } 
    }

然后在infoViewController ViewDidLoad方法中，您可以为视图设置名称和图像的值。

明白了！对于一个刚起步的人来说，这有点让人困惑，因为有很多方法可以设置一切。我一到家就告诉你！我按你说的做了尝试，但当我点击手机时什么也没发生：/我该怎么办？很抱歉，我看到你的评论太晚了。你解决了吗？是的，我解决了！我通过prepareForSegue设置了所需的信息。我现在的业力是了解更多关于CoreData的信息，以便更轻松地管理这些信息。

    override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
        if segue.identifier == "newReciep" {
            var vc = segue.destinationViewController as! DetailsViewController
            vc.delegateDetails = self
        }else if(segue.identifier == "goToInfoVC"){
            var vc = segue.destinationViewController as! InformationViewController

            let row = self.tableView.indexPathForSelectedRow()?.row
            var name = namesListArray[row]
            var image = imagesListArray[row]
            vc.name = name
            vc.image = image

        } 
    }
