SWIFT: Trigger function from TableCell

[robertybob]

Hi.

I have a ViewController, say HomeView.
It contains a TableView, say MyTable.
The table has a custom cell of class MyCell.

How can I assign delegates, protocol or whatever is needed to get a button click (addTarget method) within MyCell to trigger a function in main ViewController, HomeView?

I can't seem to use self, ParentViewController, HomeView() to get error free code.

I did manage to get the iOS Simulator to work by using 'HomeView()' instead of 'self' in the addTarget but the actual device doesn't seem to like that at all.

Thanks.

I solved this using NSNotificationCenter - not sure that this is really the best method but anything that works when it comes to Swift is ok with me.

Main Controller

Added the following to the ViewDidLoad where 'addButtonPressed' deals with the processing

NSNotificationCenter.defaultCenter().addObserver(self, selector: "addButtonPressed", name: "addToList", object: nil)
 

Custom Cell

For the custom cell I needed to call a function there using the following.

addToListButton.addTarget(self, action: "addListPressed", forControlEvents: .TouchUpInside)
 

The function 'addListPressed' then has the following code to report back to the parent controller to complete the action where 'myListButton' is a global variable storing the button pressed.

func addListPressed(sender:UIButton) {
        myListButton = sender
        NSNotificationCenter.defaultCenter().postNotificationName("addToList", object: nil)
 }
 

Hope this can help someone save some time and effort even if not a perfect solution.
