iOS开发点滴 - 如何通过Segue写代码传递数据从一个ViewController到另一个ViewController(Swift代码)

class DetailViewController: UIViewController {
    ...
    
    var destStub: SomeClass!
    ...
}

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
        if segue.identifier == "SegueName" {
            
            if let row = tableView.indexPathForSelectedRow?.row {
                
                // 这里获得你的数据
                let data = yourMethod()
                let detailViewController = segue.destinationViewController as! DetailViewController
                detailViewController.destStub = data
            }
        }
    }
