Swift - 2 tableviews和detailviewcontroller

Question

在2個viewcontrollers和detailviewcontroller上有兩個tableviews有問題，一切幾乎都可以正常工作，2個tableviews像一個魅力一樣工作，但問題是在secondviewcontroller中，我把圖像數組放到detailVC之後餐點/食物點擊，我得到了墨西哥食物，西班牙食物，意大利，克羅地亞和法國相同的3張圖片。圖像（15）確實對應於15餐。我在第二個視圖控制器中放置圖像陣列時出錯了嗎？謝謝

的ViewController

import UIKit 

class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource{ 

let textForFirstTableView = ["Italian food", "Mexican food", "Croatian food", "Spanish food", "French food"] 

let namesOfFood = [["Bolognese", "Milagnese","Pizza"], 
        ["Tortilla", "Chimichanga", "Paella"], 
        ["Burek od mesa","Grah", "Janjetina"], 
        ["Tapas", "Churros", "Flan"], 
        ["Buche de Noel", "Cherry Cake", "Onion Soup"]] 

var ObjectNamesOfFood = [String]() 

@IBOutlet weak var tableView: UITableView! 
override func viewDidLoad() { 
    super.viewDidLoad() 
    // Do any additional setup after loading the view, typically from a nib. 

    self.tableView.delegate = self 
    self.tableView.dataSource = self 
} 

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

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

    return textForFirstTableView.count 

} 

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell { 

    let cell:UITableViewCell = tableView.dequeueReusableCellWithIdentifier("cell") as! UITableViewCell 

    cell.textLabel?.text = textForFirstTableView[indexPath.row] 

    return cell 

} 

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

    self.ObjectNamesOfFood = self.namesOfFood[indexPath.row] 

    self.performSegueWithIdentifier("Segue", sender: self) 

} 

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) { 

    let driver = segue.destinationViewController as! DrugiViewController 

    var whatToPass = self.ObjectNamesOfFood 

    driver.arrayToPass = whatToPass 


} 
} 

SecondViewController

import UIKit 

class DrugiViewController: UIViewController, UITableViewDelegate, UITableViewDataSource { 

var arrayToPass:[String] = [String]() 

var picturesForEachMeal = ["1","2","3","4","5","6","7","8","9","10","11","12","13","14","15"] 

var objectpicturesForEachMeal:String! 


@IBOutlet weak var tableView2: UITableView! 
override func viewDidLoad() { 
    super.viewDidLoad() 

    // Do any additional setup after loading the view. 

    self.tableView2.delegate = self 
    self.tableView2.dataSource = self 
} 

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

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

    return arrayToPass.count 
} 

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell { 

    let cell:UITableViewCell = tableView.dequeueReusableCellWithIdentifier("cell2") as! UITableViewCell 

    cell.textLabel?.text = arrayToPass[indexPath.row] 

    return cell 

} 

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

    self.objectpicturesForEachMeal = self.picturesForEachMeal[indexPath.row] 

    self.performSegueWithIdentifier("toDetailViewController", sender: self) 

} 

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) { 

    let driver = segue.destinationViewController as! DetailViewController 

    driver.picturesToRetrieve = objectpicturesForEachMeal 

} 
} 

DetailViewController（顯示爲15餐15幅圖像）

import UIKit 

class DetailViewController: UIViewController { 

@IBOutlet weak var backgroundImage: UIImageView! 

@IBOutlet weak var slika: UIImageView! 

var picturesToRetrieve:String! 

override func viewDidLoad() { 
    super.viewDidLoad() 

    // Do any additional setup after loading the view. 

    var connection = self.picturesToRetrieve 
    self.slika.image = UIImage(named: connection) 

} 

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

在視圖控制器存儲選定的索引，並將其傳遞給DrugiViewController

func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) { 
    self.ObjectNamesOfFood = self.namesOfFood[indexPath.row] 
    self.selectedKitchen = indexPath.row 
    self.performSegueWithIdentifier("Segue", sender: self) 
} 

在DrugiViewController計算每種食物圖像索引

func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) { 
    var totalIndex = (indexPath.row) + (selectedKitchen * 3) 
    self.objectpicturesForEachMeal = self.picturesForEachMeal[totalIndex] 
    self.performSegueWithIdentifier("toDetailViewController", sender: self) 
} 

就是這樣

我必須說，如果你開始一個應用程序開始你應該在你的情況下使用包含關鍵國家的數組字典，並作爲結果在第一個字典菜和照片的數組，視圖控制器。 在第二個視圖控制器中，您應該有一個包含菜餚和照片的字典數組。 在第三個視圖中，只是一個簡單的字典，其中包含帶有菜餚和照片的字典。

但是您幾乎完成更簡單的解決方案的方法是將值從第一個表格傳遞到第二個表格，因此可以說用戶選擇了您傳遞的第2行並保留該值。

現在在第二個表格中，如果用戶選擇第3行，您將用戶選擇的行的編號乘以（3）第一行的編號在表格視圖中選擇一（2），並且您知道必須顯示最終陣列中的圖片編號6。

我希望這可以幫助你，我相信現在你知道你的想法，你將能夠完成你的項目。祝你好運！

第一視圖控制器：

var rowSelected:Int? 
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) { 
    self.ObjectNamesOfFood = self.namesOfFood[indexPath.row] 
    self.rowSelected = indexPath.row 
    self.performSegueWithIdentifier("Segue", sender: self) 
} 
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) { 
    let driver = segue.destinationViewController as! DrugiViewController 
    var whatToPass = self.ObjectNamesOfFood 
    driver.arrayToPass = whatToPass 
    driver.rowSelected = rowSelected 
} 

二視圖控制器：

var rowSelected:Int? 
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) { 
    self.objectpicturesForEachMeal = self.picturesForEachMeal[indexPath.row * self.rowSelected] 
    self.performSegueWithIdentifier("toDetailViewController", sender: self) 
} 

這是基本的想法，對不起，我不能測試它作爲我在Windows計算機現在，而應該只是工作
