Presenting UIActivityViewController initiating from inside UITableViewCell

Question

Below code work fine and presents UIActivityViewController when put inside PostsVC (Mian View Controller) but gives cell does not have a member named 'presentViewController' error when put inside tap action of a UIButton which is placed inside UITableViewCell on the same PostsVC view controller.

How do I reference to PostsVC in the last line of code to present it ?

let appAddress =  "https://itunes.apple.com/app/id978654?ls=1&mt=8"
let shareText = "Share our app "
let activityViewController : UIActivityViewController = UIActivityViewController(activityItems: [shareText, appAddress], applicationActivities: nil)
self.presentViewController(activityViewController, animated: true, completion: nil)

Answer 1

Add a weak reference to your view controller in your cell subclass. Set this in cellForRowAtIndexPath:

cell.viewController = self

Then call the presentViewController method on cell.viewController rather than the cell itself.
