从Tableview传递数据到Tableview详细信息

我有两个tableview。第一个将显示6个城市，第二个（detail tableview）将显示基于在第一个tableview中选择的单元格的细节。我为每个城市。每当用户在第一个tableview中选择一个城市时，我想采用相应的数组来填充第二个视图控制器。所以我的问题是如何通过prepareforsegue实现它。从Tableview传递数据到Tableview详细信息

声明一个变量以保持在第一TableViewController

var arrayToBePassed: YourType? 
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) { 
    switch indexPath.row { 
    case 0: 
     arrayToBePassed = yourArray 

    default: 
     break 
    } 
    self.performSegueWithIdentifier("showbuildings", sender: self) 
}

这要通过的阵列和override的UITableViewDelegate的didSelectRowAtIndexPath方法将调用prepareForSegue方法。现在我宣布你提到的数组类型的var，在第二UITableViewController和修改prepareForSegue

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) { 
    switch identifier { 
     let buildingdDetailVC = segue.destinationViewController as! CtiesTableViewController 
     buildingdDetailVC.arrayInSecondTVC = arrayToBePassed 

    default: 
     break 
    } 
}

PS：请确认你是不是overridingdidDeselectRowAtIndexPath，因为它是常犯的错误。

当你说你的数组。你在第二个视图中讨论数组吗？ –

'yourArray'是保存您在第一个'UITableViewController'中选择的行的细节的数组。在'didSelectRowAtIndexPath'中，它被复制到另一个相同类型的公共数组中，该数组是'arrayToBePassed'。 'arrayInSecondTVC'是要在第二个'TableViewController'类中声明的数组，并且在第一个控制器的'prepareForSegue'中，您将使用所选行的详细信息填充此数组。 – Mathews

它的工作！那是一个非常出色的创意伴侣 –
