Swift, Pass the array in uiPopoverController - swift

Question

I want to pass the array in my popovercontroller and sort the table view controller, sort it and give it back to the main controller.
My code for the popovercontroller
protocol MyProtocol
{
func refreshPageController(sortedProperties:[Property])
}
class SortingPopoverController: UIViewController
{
#IBOutlet var propertyNameView: UIView!
#IBOutlet var addressNameView: UIView!
#IBOutlet var imgSortingPropertyName: UIImageView!
#IBOutlet var propNameSrtImage: UIImageView!
#IBOutlet var addressSrtImage: UIImageView!
#IBOutlet var imgTickPropertyName: UIImageView!
#IBOutlet var imgTickAddress: UIImageView!
var properties:[Property] = [Property]()
var utility = Utility()
var srtProperties : [Property] = []
var mDelegate: MyProtocol?
override func viewDidLoad()
{
super.viewDidLoad()
println(properties.count)
let propertyNameSorting = UITapGestureRecognizer(target: self, action: "propertyNameSorting:")
self.propertyNameView.addGestureRecognizer(propertyNameSorting)
let addressSorting = UITapGestureRecognizer(target: self, action: "addressSorting:")
self.addressNameView.addGestureRecognizer(addressSorting)
imgTickPropertyName.hidden = true
imgTickAddress.hidden = true
}
func removeViewColorSelection(uiViewRef: UIView,tickImgShow: UIImageView)
{
uiViewRef.backgroundColor = utility.uicolorFromHex(0xF0F0F0)
uiViewRef.alpha = 0.97
tickImgShow.hidden = true
}
func addSelectedColorView(uiViewRef: UIView,tickImgShow: UIImageView)
{
uiViewRef.backgroundColor = UIColor.whiteColor()
uiViewRef.alpha = 0.97
tickImgShow.hidden = false
}
func propertyNameSorting(sender:UITapGestureRecognizer)
{
println("propertyNameSorting")
if propertyNameSrt == false
{
ascSorting == false
addSelectedColorView(propertyNameView,tickImgShow: imgTickPropertyName)
propertyNameSrt = true
removeViewColorSelection(addressNameView,tickImgShow: imgTickAddress)
addressSrt = false
if ascSorting == false
{
ascSorting = true
propNameSrtImage.image = UIImage(named: "sorting-ascending-22pt")
properties.sort(sorterForbuildingAsc)
}
else
{
ascSorting = false
propNameSrtImage.image = UIImage(named: "sorting-desending-22pt")
properties.sort(sorterForbuildingDesc)
}
}
else
{
if ascSorting == false
{
ascSorting = true
propNameSrtImage.image = UIImage(named: "sorting-ascending-22pt")
properties.sort(sorterForbuildingAsc)
}
else
{
ascSorting = false
propNameSrtImage.image = UIImage(named: "sorting-desending-22pt")
properties.sort(sorterForbuildingDesc)
}
}
mDelegate?.refreshPageController(properties)
}
func addressSorting(sender:UITapGestureRecognizer)
{
println("addressSorting")
if addressSrt == false
{
ascSorting = false
addSelectedColorView(addressNameView,tickImgShow: imgTickAddress)
propertyNameSrt = false
removeViewColorSelection(propertyNameView,tickImgShow: imgTickPropertyName)
addressSrt = true
if ascSorting == false
{
ascSorting = true
addressSrtImage.image = UIImage(named: "sorting-ascending-22pt")
}
else
{
ascSorting = false
addressSrtImage.image = UIImage(named: "sorting-desending-22pt")
}
}
else
{
if ascSorting == false
{
ascSorting = true
addressSrtImage.image = UIImage(named: "sorting-ascending-22pt")
}
else
{
ascSorting = false
addressSrtImage.image = UIImage(named: "sorting-desending-22pt")
}
}
}
Code to open the controller from the main controller
var sortingPopView = SortingPopoverController(nibName: "PopView",bundle: nil )
sortingPopView.properties = properties
var sortingPopoverController = UIPopoverController(contentViewController: sortingPopView)
sortingPopoverController.popoverContentSize = CGSize(width: 250, height: 100)
sortingPopoverController.presentPopoverFromBarButtonItem(sortingBtn, permittedArrowDirections: UIPopoverArrowDirection.Up
, animated: true)
Issue is I can't call main view controller method to sort the array.

You forgot to set the delegate on you PopoverViewController.
So when you are calling this in your PopOverController:
mDelegate?.refreshPageController(properties)
Nothing happens because mDelegate is nil
When creating the PopoverViewController you have set the delegate:
var sortingPopoverController = UIPopoverController(contentViewController: sortingPopView)
sortingPopoverController.mDelegate = self
