swift - 无法使用 segues 在 View Controller 之间传递数据(Xcode 7)(Swift)

Question

我一直在努力使用 Segues 在 View Controller 之间传递数据。我看过很多 YouTube 视频教程并在论坛上搜索，但我不明白为什么它不起作用。我没有收到任何错误消息，但是当我单击“按钮”时，模拟器崩溃了。我希望得到一些帮助!谢谢!

这是代码:

ViewController1:

    import UIKit

class ViewController: UIViewController {

    @IBOutlet var textField: UITextField!

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
        let destViewController : ViewController2 = segue.destinationViewController as! ViewController2

        destViewController.labelText = textField.text!

    }

}

ViewController2:

import Foundation
import UIKit

class ViewController2 : UIViewController {

    @IBOutlet var Label: UILabel!

    var labelText : String = ""

    override func viewDidLoad() {

        Label.text = labelText

    }

}

正如评论中所述，问题是您在 UIViewController 上使用了推送转场。

请注意，推送和模态转场已被弃用...请查看此帖子条目，如果您有任何疑问，请告诉我

What's the difference between all the Selection Segues?
