如何在 Xcode swift 3 的两个图像视图中显示相同的拾取图像？

Question

我无法弄清楚如何使用拾取的图像并同时在两个图像视图中显示它。基本上，我希望用户单击按钮然后选择一个图像，然后图像显示在两个不同的图像视图中（使用 Swift 3 和 Xcode 8）。

@IBOutlet var imageview: UIImageView!
var imagePicker = UIImagePickerController()
@IBOutlet weak var effectView: UIVisualEffectView!

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.
    imageview.image = UIImage(named:"Selfie_4072_5194.jpg")
    imagePicker.delegate = self
    imageview2.image = imageview.image
    imagePicker.delegate = self
}

@IBAction func camerabutton(_ sender: UIButton) {
    imagePicker.sourceType = UIImagePickerControllerSourceType.camera
    imagePicker.allowsEditing = true
    present(imagePicker, animated: true, completion: nil)
}

@IBAction func libraryBtn(_ sender: AnyObject) {
    imagePicker.sourceType = UIImagePickerControllerSourceType.photoLibrary
    imagePicker.allowsEditing = true
    present(imagePicker, animated: true, completion: nil)
}

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
    imageview.image = info[UIImagePickerControllerOriginalImage] as? UIImage
    self.dismiss(animated: true, completion: {})
}

@IBAction func Screenshot(_ sender: UIButton) {

我看不到您在哪里定义 imageview2 请确保您已将其添加为插座，并将其链接到您的故事板中。

@IBOutlet var imageview2: UIImageView!

您似乎也只是为imageview 设置图像尝试设置imageview2 的图像属性。

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
    if let image = info[UIImagePickerControllerOriginalImage] as? UIImage {
        imageview.image = image 
        imageview2.image = image
    }
    self.dismiss(animated: true, completion: {})
}
