XCODE 9 中的 UIImagePickerController 出错答案

【问题标题】：Error with UIImagePickerController in XCODE 9XCODE 9 中的 UIImagePickerController 出错

【问题描述】：

当我执行 mi 代码时，它显示错误：

发现扩展时遇到的错误：Error Domain=PlugInKit Code=13 "query cancelled" UserInfo={NSLocalizedDescription=query cancelled}

当我从库中选择照片或从库中取消时会发生这种情况，问题是照片出现但未分配给变量。

我的代码：

class DetalleShopViewController: UIViewController, UITextFieldDelegate, UIImagePickerControllerDelegate, UINavigationControllerDelegate {

@IBOutlet weak var imageDetalle: UIImageView!
@IBOutlet weak var textFieldDetalle: UITextField!
@IBOutlet weak var saveBtn: UIBarButtonItem!

var shops: [NSManagedObject] = []

override func viewDidLoad() {
    super.viewDidLoad()
    textFieldDetalle.delegate = self
    // Do any additional setup after loading the view.
}



override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
    if (sender as AnyObject? !== saveBtn) {return}
    print("VOY A MANDARLA")
    self.save(name: textFieldDetalle.text!, image: imageDetalle.image!)
    print("MANDADA")
}


@IBAction func cancelar(_ sender: UIBarButtonItem) {
    dismiss(animated: true, completion: nil)
}

@IBAction func seleccionImagen(_ sender: UITapGestureRecognizer) {
    textFieldDetalle.resignFirstResponder()
    let imagePickerCtrl = UIImagePickerController()
    imagePickerCtrl.delegate = self
    imagePickerCtrl.sourceType = .photoLibrary
    imagePickerCtrl.allowsEditing = false

    self.present(imagePickerCtrl, animated: true, completion: nil)
}


// MARK: UITextFieldDelegate

func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
    self.dismiss(animated: true, completion: nil)
}

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {

    let selectedImage = info[UIImagePickerControllerOriginalImage] as! UIImage
    imageDetalle.image = selectedImage
    self.dismiss(animated: true, completion: nil)
}

【解决方案1】：

也许试图解雇自己（也就是当前的 VC）正在取消选择器操作？

试试看

picker.dismiss(animated: true, completion: nil)

代替

self.dismiss(animated: true, completion: nil)

感谢您的回答，但我已经尝试过了，错误仍然存在

【解决方案2】：

试试

    if let image = info[UIImagePickerControllerOriginalImage] as? UIImage {
                imageDetalle.image = selectedImage
    }
self.dismiss(animated: true, completion: nil)

将你的选择器控制器声明为类变量并在 viewdidload 中设置它的委托。
