Swift - 在点击 TableViewCell 时打开 ViewController

Question

I have a tableView with identical cells. After selecting one of them I would like to open another ViewController. I tried this code:

func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: IndexPath) {

    let destination = EditViewController()
    navigationController?.pushViewController(destination, animated: true)

}

but it didn't open another ViewController. Can You give me a hint?

Answer 1

Most probably you just don't have the navigationController there - use rather present to show the viewController:

func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: IndexPath) {
    let destination = EditViewController()
    self.present(destination, animated: true, completion: nil)
}

Or if you want the viewController to be pushed, make sure that you embed the tableViewController into a UINavigationController .

Answer 2

Just go inside you storyboard, Select you initiate view controller, Then click on Editor > Embedded In and select Navigation controller, Then Your code will be work. This mean you have set the navigation stack for your view controllers from initial view controller.
