如何從自定義TableViewCell再次到另一個ViewController（Swift）

Question

我試圖從一個TableViewCell導航到一個詳細的VC指示細胞當前業務的細節。這裏有存根tableiewMethods：

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell { 
    let cell = tableView.dequeueReusableCellWithIdentifier("YelpTableBusinessCell", forIndexPath: indexPath) as! YelpTableBusinessCell 
    var business:Business = Business(dictionary: businessArray[indexPath.row] as! NSDictionary) 
    cell.business = business 
    return cell 
} 
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) { 
    businessToUseTVC = Business(dictionary: businessArray[indexPath.row] as! NSDictionary) 
    performSegueWithIdentifier("businessToDetailVC", sender: view); 

} 
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) { 
    if let cell = sender as? YelpTableBusinessCell { 
     if segue.identifier == "businessToDetailVC" { 
      if let ivc = segue.destinationViewController as? AttractionsDetailViewController { 
       ivc.businessToUse = self.businessToUseTVC 
      } 
     } 
    } 

} 

我設置了兩個斷點，一個在prepareForSegue方法，一個在didSelectRowAtIndexPath方法

我初始化businessToUseVTC變量didSelectRowAtIndexPath，但是當我運行應用程序，當我在AttractionsDetailVC，其中包含這段代碼，

func loadYelpInfo() { 
     businessName.text = businessToUse.name 
     let thumbImageViewData = NSData(contentsOfURL: businessToUse.imageURL!) 
     thumbImage.image = UIImage(data: thumbImageViewData!) 
     let reviewImageData = NSData(contentsOfURL: businessToUse.ratingImageURL!) 
     reviewImage.image = UIImage(data: reviewImageData!) 
     categories.text = businessToUse.categories 
     reviews.text = "\(businessToUse.reviewCount!) Reviews" 
     distanceLabel.text = businessToUse.distance 
    } 

代碼休息，說businessToUse，設置裏面DetailsVC，是零。

任何幫助將不勝感激。

Answer 1

首先，確保你從控制器拖動VIEWCONTROLLER，而不是單個單元格。

二，發件人不是YelpTablseBusinessCell類型，我相信這是你的問題。
