從Tableview傳遞數據到Tableview詳細信息

Question

我有兩個tableview。第一個將顯示6個城市，第二個（detail tableview）將顯示基於在第一個tableview中選擇的單元格的細節。我爲每個城市。每當用戶在第一個tableview中選擇一個城市時，我想採用相應的數組來填充第二個視圖控制器。所以我的問題是如何通過prepareforsegue實現它。

//First tableview as initial view

Answer 1

聲明一個變量以保持在第一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) 
} 

這要通過的陣列和override的UITableViewDelegate的didSelectRowAtIndexPath方法將調用prepareForSegue方法。現在我宣佈你提到的數組類型的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：請確認你是不是overridingdidDeselectRowAtIndexPath，因爲它是常犯的錯誤。
