我有两个tableviews。第一个是显示6个城市，第二个（详细的tableview）将显示基于第一个tableview上选择的单元格的详细信息。我为每个城市创建6个数组。每次用户选择在第一个tableview上的一个城市，我想采取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用prepareforsegue实现它。

答案 0 :(得分：1)
声明一个变量来保存要传递的数组，并在override
didSelectRowAtIndexPath UITableViewDelegate TableViewController方法
var arrayToBePassed: YourType?
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
switch indexPath.row {
case 0:
arrayToBePassed = yourArray
default:
break
}
self.performSegueWithIdentifier("showbuildings", sender: self)
}
这将调用prepareForSegue方法。现在声明您提到的数组类型的var，在第二个UITableViewController中修改prepareForSegue
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
switch identifier {
let buildingdDetailVC = segue.destinationViewController as! CtiesTableViewController
buildingdDetailVC.arrayInSecondTVC = arrayToBePassed
default:
break
}
}
PS：请确保您不是overriding didDeselectRowAtIndexPath，因为这是一个常见的错误。
