UIMenuController not showing up the menu

Question

I am very new to iOS. I am trying to show a pop up menu,but some how I am unable to display menu. Please help. Here is my code:

//DidLoad function to initialize UILongPRessGestureRecognizer

override func viewDidLoad()  
{     
        super.viewDidLoad()  
        var longprss : UILongPressGestureRecognizer = UILongPressGestureRecognizer(target: self, action: Selector("display:"))   
        self.tableView.addGestureRecognizer(longprss)   
}



   //Bool function Can become first responder set to true

     override func canBecomeFirstResponder() -> Bool {
           return true
    }

 //become first responser set to true
   override func becomeFirstResponder() -> Bool {
        return true
    }
    //action handler of longPressGesture

    func display(gesture: UILongPressGestureRecognizer)
    {

        self.becomeFirstResponder()
        println("Is first responder")

        var menu = UIMenuController.sharedMenuController()
        var deleteItem = UIMenuItem(title: "Delete", action: Selector("deleteLine"))
        var editItems = UIMenuItem(title: "Edit", action: Selector("editrow"))
        menu.menuItems = [deleteItem ,editItems]

        menu.setTargetRect(CGRect(x: 100, y: 80, width: 100, height: 50), inView: UIView())
        menu.setMenuVisible(true, animated: true)

    }

//perform action method
override func tableView(tableView: UITableView, performAction action: Selector, forRowAtIndexPath indexPath: NSIndexPath, withSender sender: AnyObject!) {

}
//can perform action method.

    override func canPerformAction(action: Selector, withSender sender: AnyObject?) -> Bool {
        if action == Selector("Delete")
        {
            return true
        }
        return false
    }

Please help me to display popup menu.

Thank you in advance.

menu.setTargetRect(CGRect(x: 100, y: 80, width: 100, height: 50), inView: UIView()) Why you are displaying in a new instance of a view. You can display in tableView or tablecellview. Where do you want to display? — Shashi3456643, Jan 30 '15 at 11:56
@Shashi3456643 Thank you. I want to display this in same view. — Diamond King, Jan 30 '15 at 12:49

I have tested code for displaying menu in UIView Its working. You can do for UItablecell or uitableView
Do exactly the way I have done it will work
you don't need to add this delegate, remove it from your code
   override func becomeFirstResponder


example


 override func viewDidLoad()
{
    super.viewDidLoad()
    var longprss : UILongPressGestureRecognizer = UILongPressGestureRecognizer(target: self, action: Selector("display:"))
    self.view.addGestureRecognizer(longprss)
}

override func canBecomeFirstResponder() -> Bool {
    return true
}



override func canPerformAction(action: Selector, withSender sender: AnyObject?) -> Bool
{
    println(action);
    if(action == Selector("deleteLine:") || action == Selector("editRow:"))
    {
        return true;

    }
    else
    {
        return false;
    }
}

func deleteLine(sender: AnyObject?) {

    println("delete line")

}

func editRow(sender: AnyObject?) {

    println("edit row");
}


//action handler of longPressGesture

func display(gesture: UILongPressGestureRecognizer)
{

    gesture.view?.becomeFirstResponder()

    println("Is first responder")
    var menu = UIMenuController.sharedMenuController()
    var deleteItem = UIMenuItem(title: "Delete", action: Selector("deleteLine:"))
    var editItems = UIMenuItem(title: "Edit", action: Selector("editRow:"))
    menu.menuItems = [deleteItem ,editItems]

    menu.setTargetRect(CGRect(x: 100, y: 600, width: 100, height: 50), inView: self.view)
    menu.setMenuVisible(true, animated: true)

}

Yes it is working, but the menu is displaying at fixed position not on the cell which is selected. Well, Thank you so much for the solution. — Diamond King, Jan 31 '15 at 06:18
Thats why I asked you where would you like to display the menu. I understand you want to display in tablecellview. user will long press on tablecellview and menu will popup. I am going to post another answer which will have complete code. — Shashi3456643, Jan 31 '15 at 18:12

You override -[UIResponder becomeFirstResponder] but don't call its super implementation. This basically turns the call into a no-op, and fails to install you in the responder chain. Unless you need to perform specific actions when becoming the first responder you don't need to override this method.
