Swift：當選擇一個tableview單元格時關閉PopOver

Question

我有兩個控制器。第一個有一個導航欄，裏面有一個書籤按鈕，我按下來顯示我的第二個控制器，裏面有一個tableview。

Example project from this link : http://www.koraybirand.co.uk/download/xcode/PopTest.zip

我希望能夠選擇一個單元格，然後關閉該酥料餅的視圖。

另外一個奇怪的現象是，第一個單元格顯示警告視圖 - 控制其在iPhone上，但在iPad上的酥料餅的工作正常，突然調整到alerviewcontroller的大小。

這裏是我的主視圖控制器：

class ViewController: UIViewController, UIPopoverPresentationControllerDelegate { 

override func viewDidLoad() { 
    super.viewDidLoad() 
    // Do any additional setup after loading the view, typically from a nib. 
} 

override func didReceiveMemoryWarning() { 
    super.didReceiveMemoryWarning() 
    // Dispose of any resources that can be recreated. 
} 

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) { 
    if segue.identifier == "popoverSegue" { 

     let popoverViewController = segue.destinationViewController as! UIViewController 
     popoverViewController.modalPresentationStyle = UIModalPresentationStyle.Popover 
     popoverViewController.popoverPresentationController!.delegate = self 
    } 
} 

func adaptivePresentationStyleForPresentationController(controller: UIPresentationController) -> UIModalPresentationStyle { 
    return UIModalPresentationStyle.None 
} 


} 

這裏是我酥料餅：

class menuViewController: UIViewController, UITableViewDelegate, UITableViewDataSource { 

var links : [String] = ["Share", "Manage"] 
var currentPopover:UIPopoverController! 

@IBOutlet weak var tableView: UITableView! 

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

func numberOfSectionsInTableView(tableView: UITableView) -> Int { 
    return 1 
} 

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

    if indexPath.item == 0 { 
     let alertController = UIAlertController(title: "Share", message: "No Bookmarks to Share", preferredStyle: .Alert) 
     let cancelAction = UIAlertAction(title: "Dismiss", style: .Cancel) { (_) in } 
     alertController.addAction(cancelAction) 
     self.presentViewController(alertController, animated: true) {} 
    } 
} 

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell { 
    let cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as! UITableViewCell 

    cell.textLabel?.text = links[indexPath.row] as String 
    return cell 
} 

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

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



} 

感謝。

Answer 1

self.dismissViewControllerAnimated（真，完成：無）

在menuViewController足以解僱酥料餅。所以，代碼看起來就像這樣：

func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) { 
    if indexPath.item == 0 { 
     let alertController = UIAlertController(title: "Share", message: "No Bookmarks to Share", preferredStyle: .Alert) 
     let cancelAction = UIAlertAction(title: "Dismiss", style: .Cancel) { (_) in } 
     alertController.addAction(cancelAction) 
     self.presentViewController(alertController, animated: true) {} 

     self.dismissViewControllerAnimated(true, completion: nil) 
    } 
}
