点击单元格时推送到详细视图的问题

Question

我刚刚为我的单元格添加了一个详细视图，但我无法选择要推送到详细视图的单元格。

出于某种原因，当我正常点击其中一个细胞时，没有任何反应。但是，当我在执行搜索后点击其中一个单元格时，单元格会推送到详细视图。我查看了所有代码，但我无法弄清问题是什么。

最初我以为是这一行：

    cell.selectionStyle = UITableViewCellSelectionStyle.None

但我对此进行了评论，并没有起到什么作用。

以下是相关代码（抱歉长度！）：

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
