NSIndexPath不具有迅速

名爲行成員我有這樣的代碼：NSIndexPath不具有迅速

class ViewController: UITableViewController { 

    var myArr = [(id:1, name:"1123", description:"d1", image:"palm-tree.png"), (id:2, name:"23", description:"d2", image:"palm-tree.png"), 
       (id:3, name:"3", description:"d3", image:"palm-tree.png"), (id:4, name:"4", description:"d4", image:"palm-tree.png")] 

    override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) { 
     if segue.identifier == "showDetail" { 
      var indexPath = tableView.indexPathForSelectedRow() 
      let destinationViewController:DetailViewController = segue.destinationViewController as DetailViewController 
      destinationViewController.myArr = myArr[indexPath.row] 
     } 
    } 

}

而且我有一個錯誤NSIndexPath沒有一個成員命名的行。如何解決這個問題？

謝謝！

更新：

class ViewController: UITableViewController { 
    struct Item { 
     let id: Int 
     let name: String 
     let description: String 
     let image: String 
    } 

    var myArr = [Item(id:1, name:"1123", description:"d1", image:"palm-tree.png"), 
     Item(id:2, name:"23", description:"d2", image:"palm-tree.png"), 
     Item(id:3, name:"3", description:"d3", image:"palm-tree.png"), 
     Item(id:4, name:"4", description:"d4", image:"palm-tree.png")] 
    override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) { 
     if segue.identifier == "showDetail" { 
      if let indexPath = tableView.indexPathForSelectedRow() { 
       let destinationViewController = segue.destinationViewController as DetailViewController 
       destinationViewController.myArr = [myArr[indexPath.row]] 
      } 
     } 
    } 

}

而且DetailViewController：

class DetailViewController: UIViewController { 
    struct Item { 
     let id: Int 
     let name: String 
     let description: String 
     let image: String 
    } 
    var myArr = [Item(id:1, name:"1123", description:"d1", image:"palm-tree.png")] 
}

tableView.indexPathForSelectedRow()返回一個可選NSIndexPath - 你需要解開它訪問row屬性：

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) { 
    if segue.identifier == "showDetail" { 
     if let indexPath = tableView.indexPathForSelectedRow() { 
      let destinationViewController = segue.destinationViewController as DetailViewController 
      destinationViewController.myArr = [myArr[indexPath.row]] 
     } 
    } 
}

**'Int'不能轉換爲'Range '** – tim 2014-10-07 17:27:21

看起來像你的'DetailViewController'正在等待一個數組 - 我已經更新了答案，所以它將得到一個包含當前行數據的單元數組'myArr'。（這是不好的變量名稱，是描述性的！） – 2014-10-07 17:29:44

對不起，我的錯誤 - 我忘了'DetailViewController'：var myArr：（id：Int，name：String，description：String，img：String）=（ id：0，name：「」，description：「」，img：「」） – tim 2014-10-07 17:36:42
