Swift - Segue from Button inside a cell

问题

i have a custom cell attached to TableViewCell class, and i have a button inside that custom cell, i want whey i press the button it segues to another view controller, but the:

performSegueWithIdentifier(identifier: String, sender: AnyObject?)

function is not recognised, how to fix that ?

Edit:

回答1:

-performSegueWithIdentifier: method is declared in UIViewController. So you can't just call it in UITableViewCell subclass.

You can add an action to that button when you are creating cell in -tableView:cellForRowAtIndexpath: method. Then you can call -performSegueWithIdentifier: method in that action method. Here is example assuming we are in UITableViewController subclass:

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as UITableViewCell

    cell.button.addTarget(self, action: "someAction", forControlEvents: .TouchUpInside)

    return cell
}

And here is action method:

func someAction() {
    self.performSegueWithIdentifier("moveToView", sender: self)
}

回答2:

You need a custom class for your cell. In that class, create an @IBAction as response to the button click. In that action, perform your segue.

回答3:

If you are using Interface Builder:

Connect your firstViewController to the secondViewController - and create a Segue Identifier.

Then you are able to use

performSegueWithIdentifier(identifier: String, sender: AnyObject?)
