错误与在prepareForSegue在Swift

Question

我想要它，以便我可以在我的ViewController视图中填充8个UITextFields，然后当我点击我的按钮'nextView'被调用。如果满足所有要求（有字符串的UIImage），我使用self.presentViewController（...）导航到我的下一个视图。但是，在下一个视图中，我的8个图像没有更新（image1 - image8）。我该如何解决这个问题。谢谢。以下是我的代码，任何建议都会很棒！

class ViewController : UIVewController { 

    // field1 - field8 are defined here as UITextFields 

    @IBAction func nextView(sender: UIButton) { 

     if (my requirements are met) { 

       let storyboard = UIStoryboard(name: "Main", bundle: nil) 

       let nextViewController : UIViewController = storyboard.instantiateViewControllerWithIdentifier("View Two") as UIViewController 

       self.presentViewController(nextViewController, animated: true, completion: nil) 

     } else { 

       // nothing happens 

     } 


    } 

    override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) { 

     let Dest : ViewTwo = segue.destinationViewController as! ViewTwo 

     Dest.c1 = field1.text! // c1 - c8 are strings in ViewTwo 
     Dest.c2 = field2.text! // field1 - field8 are UITextFields in ViewController 
     Dest.c3 = field3.text! 
     Dest.c4 = field4.text! 
     Dest.c5 = field5.text! 
     Dest.c6 = field6.text! 
     Dest.c7 = field7.text! 
     Dest.c8 = field8.text! 

    } 

} 

class ViewTwo : UIViewController { 

    var c1 = String() 
    var c2 = String() 
    var c3 = String() 
    var c4 = String() 
    var c5 = String() 
    var c6 = String() 
    var c7 = String() 
    var c1 = String() 
    var c8 = String() 

    override func viewDidLoad() { 

      image1.image = UIImage(named: "\(c1)") // image1 - image8 are UIImageView s in ViewTwo 
      image2.image = UIImage(named: "\(c2)") 
      image3.image = UIImage(named: "\(c3)") 
      image4.image = UIImage(named: "\(c4)") 
      image5.image = UIImage(named: "\(c5)") 
      image6.image = UIImage(named: "\(c6)") 
      image7.image = UIImage(named: "\(c7)") 
      image8.image = UIImage(named: "\(c8)") 

      image1.frame = CGRectMake(20, 219, 80, 80) // these are the image’s dimensions 
      image3.frame = CGRectMake(20, 302, 80, 80) 
      image5.frame = CGRectMake(20, 385, 80, 80) 
      image7.frame = CGRectMake(20, 468, 80, 80) 
      image2.frame = CGRectMake(220, 219, 80, 80) 
      image4.frame = CGRectMake(220, 302, 80, 80) 
      image6.frame = CGRectMake(220, 385, 80, 80) 
      image8.frame = CGRectMake(220, 468, 80, 80) 

      self.view.addSubview(image1) // here I add the images to the view 
      self.view.addSubview(image2) 
      self.view.addSubview(image3) 
      self.view.addSubview(image4) 
      self.view.addSubview(image5) 
      self.view.addSubview(image6) 
      self.view.addSubview(image7) 
      self.view.addSubview(image8) 


    } 

}

两个ViewControllers与SEGUE，没有按钮连接到视图控制器两人随后执行以下操作：

@IBAction func nextView(sender: UIButton) { 
     if (my requirements are met) { 
       performSegueWithIdentifier("yourIdentifier", sender: nil) 
     } else { 
       // nothing happens 
     } 
    } 

    override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) { 
     if segue.identifier == "yourIdentifier" { 
     let viewTwo = segue.destinationViewController as! ViewTwo 

     viewTwo.c1 = field1.text! // c1 - c8 are strings in ViewTwo 
     viewTwo.c2 = field2.text! // field1 - field8 are UITextFields in ViewController 
     viewTwo.c3 = field3.text! 
     viewTwo.c4 = field4.text! 
     viewTwo.c5 = field5.text! 
     viewTwo.c6 = field6.text! 
     viewTwo.c7 = field7.text! 
     viewTwo.c8 = field8.text! 
} 

    } 

}
