【中文标题】将数据从 Tableview 传递到 Tableview 详细信息【英文标题】:Pass data from Tableview to Tableview Detail 【发布时间】:2016-04-05 23:25:48 【问题描述】:我有两个表格视图。第一个将显示 6 个城市,第二个(详细表格视图)将根据第一个表格视图上选择的单元格显示详细信息。我为每个城市创建 6 个数组。每次用户选择第一个 tableview 上的一个城市,我想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使用 prepareforsegue 实现它。

【问题讨论】:
【参考方案1】:在第一个TableViewController
中声明一个变量来保存要传递的数组和override
UITableViewDelegate
的didSelectRowAtIndexPath
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。现在声明你提到的数组类型的var
,在第二个UITableViewController
并修改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。
【讨论】:
当你说你的数组时。你说的是secondview中的数组吗?yourArray
是包含您在第一个 UITableViewController
中选择的行的详细信息的数组。在didSelectRowAtIndexPath
中,它被复制到另一个相同类型的公共数组中,即arrayToBePassed
。 arrayInSecondTVC
是要在第二个 TableViewController
类中声明的数组,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。以上是关于将数据从 Tableview 传递到 Tableview 详细信息的主要内容,如果未能解决你的问题,请参考以下文章
