ios - 无法在我的应用程序中打开相机胶卷

Question

无法在我的应用程序中打开相机胶卷。 在此 Controller 中，我的目标是选择照片并将其发送到服务器。 照片 Controller 就像

import Foundation
import UIKit
class PhotoController:UIViewController,UINavigationControllerDelegate,UIImagePickerControllerDelegate{
    @IBOutlet weak var myImageView: UIImageView!

    @IBAction func PhotoSelect(_ sender: Any) {
    }

    @IBAction func PhotoSend(_ sender: Any) {
        let myPickerController = UIImagePickerController()
        myPickerController.delegate = self;
        myPickerController.sourceType = UIImagePickerControllerSourceType.photoLibrary

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

      private func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject])

    {
        myImageView.image = info[UIImagePickerControllerOriginalImage] as? UIImage

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

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

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

  }

当我在真实的 iPhone 上运行我的应用程序时，我的应用程序停止并发生此错误。 error message

我不知道为什么会发生这个错误。不是代码而是其他设置错误，对吧？我该如何解决这个问题？

我的info.plist是 info.plist

Answer 1

我认为您没有在 info.plist 中提供隐私安全。

隐私 - 相机使用说明 -> 相机。

隐私 - 照片库使用说明 -> 适用于照片库。

if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.photoLibrary) {
       let imagePicker = UIImagePickerController()
       imagePicker.delegate = self
       imagePicker.sourceType = UIImagePickerControllerSourceType.photoLibrary
       self.present(imagePicker, animated: true, completion: nil)
 }

尝试上面的代码，如果它不起作用，请检查连接检查器中的 IBAction PhotoSend Method 导出。
