How to call tableview controller method within cell class

I was removing cells from table view today with a button in the cell.

So after calling the remove function from the API, here comes the question, how do you refresh the table view's content.

Firstly, create a protocol method in your cell class

protocol BookingTableViewCellDelegate {

    func reloadTableViewData()

}

then 

var delegate: BookingTableViewCellDelegate?

in table view controller

    func reloadTableViewData() {

        println("reloading data")

        self.items.removeAllObjects()

        getBookings()

        self.myBookingTableView.reloadData()

    }

and add 

cell.delegate = self at cellForRowAtIndexPath

then finally, in your cell class:

self.delegate?.reloadTableViewData()
