在表格视图中点击单元格不会执行任何操作

Question

我一直在我的应用程序中的某个表格视图中选择问题。基本上，问题是我只能通过点击作为搜索结果的单元格才能继续访问另一个视图控制器。出于某种原因，我无法在标准表格视图中点按单元格。

当我正常点击一个单元时，没有任何反应。但是，如果我使用搜索栏搜索单元格，则可以点击单元格，并且它们将按照预期继续到另一个视图控制器。我无法弄清楚为什么。

这是我的代码：

override func tableView(tableView: UITableView?, numberOfRowsInSection section: Int) -> Int { 
    // #warning Incomplete method implementation. 
    // Return the number of rows in the section. 

    if tableView == self.searchDisplayController?.searchResultsTableView { 
     return searchResults.count 
    } else { 
    if names.count == 0 { 
     if enterButtonTapped == false { 
      backgroundLabel.text = "Before you add any transactions, you must first set a budget. You can do this by tapping the 'Budget' tab." 
     } else { 
      backgroundLabel.text = "You haven't added any transactions yet. Tap the add button to add a new transaction." 
     } 
     backgroundLabel.frame = CGRectMake(0, 0, self.view.bounds.width, self.view.bounds.height) 
     backgroundLabel.numberOfLines = 0 
     backgroundLabel.textAlignment = NSTextAlignment.Center 
     backgroundLabel.sizeToFit() 
     backgroundLabel.hidden = false 
     backgroundLabel.textColor = UIColor.lightGrayColor() 
     clearButton.enabled = false 

     self.tableView.backgroundView = backgroundLabel 
     self.tableView.separatorStyle = UITableViewCellSeparatorStyle.None 
     self.tableView.scrollEnabled = false 
     return 0 
    } else { 
     backgroundLabel.hidden = true 
     self.tableView.separatorStyle = UITableViewCellSeparatorStyle.SingleLine 
     self.tableView.scrollEnabled = true 
     clearButton.enabled = true 
     return names.count 
    } 
    } 
} 

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell { 
    var cell:CustomTransactionTableViewCell = self.tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as CustomTransactionTableViewCell 
    cell.selectionStyle = UITableViewCellSelectionStyle.None 

    if tableView == self.searchDisplayController?.searchResultsTableView { 
     cell.paymentNameLabel.text = (searchResults.objectAtIndex(indexPath.row)) as? String 
     //println(searchResults.objectAtIndex(indexPath.row)) 
     var indexValue = names.indexOfObject(searchResults.objectAtIndex(indexPath.row)) 
     cell.costLabel.text = (values.objectAtIndex(indexValue)) as? String 
     cell.dateLabel.text = (dates.objectAtIndex(indexValue)) as? String 

     if images.objectAtIndex(indexValue) as NSObject == 0 { 
      cell.paymentArrowImage.hidden = false 
      cell.creditArrowImage.hidden = true 
     } else if images.objectAtIndex(indexValue) as NSObject == 1 { 
      cell.creditArrowImage.hidden = false 
      cell.paymentArrowImage.hidden = true 
     } 
     //This works, unless there are two payments with the same name. To revert to previous version, remove tableView if statement and just keep code below the else. 
    } else { 
     cell.paymentNameLabel.text = (names.objectAtIndex(indexPath.row)) as? String 
     cell.costLabel.text = (values.objectAtIndex(indexPath.row)) as? String 
     cell.dateLabel.text = (dates.objectAtIndex(indexPath.row)) as? String 

     if images.objectAtIndex(indexPath.row) as NSObject == 0 { 
      cell.paymentArrowImage.hidden = false 
      cell.creditArrowImage.hidden = true 
     } else if images.objectAtIndex(indexPath.row) as NSObject == 1 { 
      cell.creditArrowImage.hidden = false 
      cell.paymentArrowImage.hidden = true 
     } 
    } 
    return cell 
} 

override func tableView(tableView: UITableView, canEditRowAtIndexPath indexPath: NSIndexPath) -> Bool { 
    if tableView == self.searchDisplayController?.searchResultsTableView { 
     return false 
    } else { 
     return true 
    } 
} 

视图控制器通过推SEGUE连接到故事板的单元格。

起初我怀疑这是此行（但它不是）：

cell.selectionStyle = UITableViewCellSelectionStyle.None 

任何想法？

这个问题其实很简单。我只需要将表格视图属性中的选择设置从“无选择”更改为“单选”。
