Swift, Pass data back from popover to view control

Question

I have sorted the original array in popover controller. Now I want to send that array back to the original view controller for tableview and map view.

Below is my code

 If propertyNameSrt == false
    {
        if ascSorting == false
        {
            properties.sort(sorterForbuildingAsc)
        }
        else
        {
            properties.sort(sorterForbuildingDesc)
        }


    }

My array is properties which includes custom object. How can pass this to my original view controller? Thanks in advance, Dhaval.

Answer 1

You can use delegate(protocol) methods to send back data to previous view controller.

IN CURRENT VC:

protocol MyProtocol: class
{
    func sendArrayToPreviousVC(myArray:[AnyObject])
}

Make a var in your class.

weak var mDelegate:MyProtocol?

Now call the protocol method when you pop the view controller, with your "properties" array as parameter.

mDelegate?.sendArrayToPreviousVC(properties)

IN PREVIOUS VC:

In your previous VC, set the mDelegate property to self, when you push the current VC.

currentVC.mDelegate = self
//PUSH VC

Now implement the protocol method in your previous VC.

func sendArrayToPreviousVC(myArray:[AnyObject]) {
    //DO YOUR THING
}
