如何從Swift中的表格單元格中移除

Question

這是我必須在主表格視圖控制器上使用的代碼我只是不知道如何去轉換到新的視圖控制器以顯示選定的單元格有關選擇任何單元格的更多內容。

import UIKit 

class MainVC: UITableViewController, UITableViewDelegate, UITableViewDataSource { 

@IBOutlet var Table1: UITableView! 
var postArray: [[String]] = [] 

var postSubject = "" 
var postDescription = "" 
var postDate = "" 

override func viewDidLoad() { 
    super.viewDidLoad() 
    fetchData() 
} 

func fetchData() { 
    println("success1") 
    postArray = [] 

    let httpMethod = "GET" 

    let timeout = 15 

    let urlAsString = "http://cgi.soic.indiana.edu/~team12/main_requests.php" 
    let url = NSURL(string: urlAsString)! 

    let urlRequest = NSMutableURLRequest(URL: url, 
     cachePolicy: .ReloadIgnoringLocalAndRemoteCacheData, 
     timeoutInterval: 15.0) 

    urlRequest.HTTPMethod = httpMethod 

    let queue = NSOperationQueue() 
    println("success2") 

    NSURLConnection.sendAsynchronousRequest(urlRequest, 
     queue: queue, 
     completionHandler: {(response: NSURLResponse!, 
      data: NSData!, 
      error: NSError!) in 

      if data.length > 0 && error == nil{ 
       let html = NSString(data: data, encoding: NSUTF8StringEncoding) 

      } else if data.length == 0 && error == nil{ 
       println("Nothing was downloaded") 
      } else if error != nil{ 
       println("Error happened = \(error)") 
      } 

      if data.length > 0 && error == nil { 
       let html = NSString(data: data, encoding: NSUTF8StringEncoding) 

       var newArrayofDicts : NSMutableArray = NSMutableArray() 
       var arrayOfDicts : NSMutableArray? = NSJSONSerialization.JSONObjectWithData(data, options:NSJSONReadingOptions.MutableContainers, error:nil) as? NSMutableArray 
       println("successmutable") 

       if arrayOfDicts != nil { 
        for item in arrayOfDicts! { 

         if var dict = item as? NSMutableDictionary{ 

          if dict["subject"] != nil{ 
           self.postSubject = dict["subject"] as String 
           self.postDescription = dict["subject"] as String 
           self.postDate = dict["date"] as String 
          self.postArray.append([self.postSubject,self.postDescription,self.postDate]) 
           println("successpost") 

          } 
         } 
        } 
       } 
      } 
     } 
    ) 
    sleep(1) 
} 


override func viewDidAppear(animated: Bool) { 
    super.viewDidAppear(animated) 
    fetchData() 
    tableView.reloadData() 
    println("successanime") 

} 

override func didReceiveMemoryWarning() { 
    super.didReceiveMemoryWarning() 
} 

override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int { 
    return postArray.count 
} 

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell { 
    println("successoverride") 

    let cell = tableView.dequeueReusableCellWithIdentifier("UpdateCell", forIndexPath: indexPath) 
     as UITableViewCell 
    println("successupdatecell") 

    cell.textLabel.text = postArray[indexPath.row][1] 

    cell.detailTextLabel?.text = postArray[indexPath.row][2] 

    println("success3") 
    return cell 
}

嘗試此方法

func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) { 
... 
} 

或者你也可以按ctrl原型細胞拖動到下一viewController做直在故事板。

希望這有助於！

編輯

如果你想原因請看下一view controller編程，那麼你可以做兩種：

performSegueWithIdentifier("yourSegueName", sender: nil) 

或者：

presentViewController(nextViewController, animated: true, completion: nil)
