Swift-2 TableView和detailviewcontroller

在2个ViewController和detailviewcontroller上有2个TableView的问题，一切都很正常，2个TableView工作得很好，但问题是在secondviewcontroller中，我在每顿饭/食物被点击后将一组图像切换到detailVC，我得到了同样的3张墨西哥食物、西班牙食物、意大利食物的图像，克罗地亚语和法语。图像（15）与15顿饭对应。我在第二视图控制器中放置图像数组时出错了吗？多谢各位

我必须说，如果您从一开始就启动应用程序，那么这不是最好的方法。在您的情况下，您应该使用包含关键国家/地区的数组字典，从而在第一视图控制器中使用字典盘和照片数组。 在第二个视图控制器中，您应该有一个包含碟片和照片的字典数组。 在第三个视图中，只是一个简单的字典，其中包含一个带有dish和photo的字典

但是，对于您来说，如何完成更简单的解决方案是将值从第一个表传递到第二个表，因此假设用户选择了第2行，您将传递并保留该值

现在在第二个表中，如果用户选择了第3行，则将用户选择的行数（3）乘以表视图1（2）中选择的第一行数，您知道必须在最终数组中显示图片编号6

我希望这对你有帮助，我相信现在你知道了这个想法，你将能够完成你的项目。祝你好运

第一视图控制器：

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
}

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

第二视图控制器：

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
}

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

这是基本的想法，很抱歉，我无法测试它，因为我现在在Windows计算机中，但应该只在视图控制器中工作，存储选定的索引并将其传递给DrugiViewController

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

}

在DrugiViewController中，计算每个食品图像索引

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

就是这样

我很困惑，你的应用程序有5个国家，table view 1将1到5之间的索引传递给second view controller，second view controller始终有3个盘子，因此它将始终将1到3之间的值传递给view controller。因此，在第二个视图控制器中，您可以看到的唯一内容是前3道菜是的，我有15道菜，分别对应于5个国家，意大利人有3道菜，墨西哥人有3道菜，西班牙人有3道菜，依此类推，以及如何显示每道菜的图像，我有15道图像，只显示了3道菜。因此，当我点击墨西哥食物，然后点击玉米饼，如何显示玉米饼图片，它只显示图像数组的索引0,1,2，如何为每种食物显示15个图像，我在下面解释了如何为您的实现实现修复，以及我将如何处理该问题。我希望你能理解。非常感谢，但你的简单答案有点难理解，我是swift的初学者，我已经对这个应用程序感到困惑，再次感谢thx的帮助，所以如果我将图像数组移动到first view controller，那么我还遇到了一个问题，如何在名称数组中“合并”索引0-15到索引0-5，是的，问题，…忘记第一部分，实现第二部分，将行号从vc1传递到vc2，将你传递的行号乘以在vc2中选择的新行号，然后传递到你的视图，现在你有了正确的值抱歉打扰你，我在谷歌上搜索了如何在swift中传递行号，但找不到任何相关信息，我以前从来没有这样做过，尤其是乘行。我成功地实现了你的代码，但现在它在不同的餐点上显示不同的图片，就像图片的索引与餐点的索引不匹配一样。你需要弄清楚数组中的顺序，以便现在显示正确的图片，只要根据需要进行更改即可
