Ios 当我点击UIImagePicker galary的图像按钮在iPad上选择图像时，应用程序崩溃了，为什么？

我使用UIImagePicker拾取图像，iPhone gallery可以很好地拾取图像。但当我在xcode中在iPad上测试应用程序时，当我点击图像按钮时，应用程序崩溃了，我不知道为什么

代码如下：

 @IBAction func addProfileBtnAction(_ sender: Any) {

   let actionSheetController: UIAlertController = UIAlertController(title: nil, message: nil, preferredStyle: .actionSheet)

   //Create and add the Cancel action
   let cancelAction: UIAlertAction = UIAlertAction(title: "Cancel", style: .cancel) { action -> Void in
       //Just dismiss the action sheet
   }
   actionSheetController.addAction(cancelAction)
   //Create and add first option action
   let takePictureAction: UIAlertAction = UIAlertAction(title: "TakePhoto", style: .default) { action -> Void in
       //Code for launching the camera goes here
       self.openCameraPicker()
   }
   actionSheetController.addAction(takePictureAction)
   //Create and add a second option action
   let choosePictureAction: UIAlertAction = UIAlertAction(title: "ChooseFromLibrary", style: .default) { action -> Void in
       //Code for picking from Gallery  goes herece
       self.openPhotoGallery()
   }
   actionSheetController.addAction(choosePictureAction)
   //Present the AlertController
   self.present(actionSheetController, animated: true, completion: nil)
   }
   func openCameraPicker() {
   picker.sourceType = UIImagePickerController.SourceType.camera
   picker.cameraCaptureMode = .photo
   picker.modalPresentationStyle = .fullScreen
   present(picker,animated: true,completion: nil)
   }
  func openPhotoGallery() {
   picker.sourceType = .photoLibrary
   picker.mediaTypes = UIImagePickerController.availableMediaTypes(for: .photoLibrary)!
   present(picker, animated: true, completion: nil)
   }
  // MARK: - UIImagePickerControllerDelegate Methods
  func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
   if let image = info[UIImagePickerController.InfoKey.originalImage] as? UIImage {
       //pickedImage  = image
       imgPick.image = image
   }
   dismiss(animated: true, completion: nil)
  }
 func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
   dismiss(animated: true, completion: nil)
 }

我已经通过给出断点检查了崩溃点，当涉及到

openPhotoGallery（）

时，它就会崩溃

UIViewAlertForUnsatifiableConstraints可在调试器中捕获此信息

中列出的UIView上UIConstraintBasedLayoutDebugging类别中的方法也可能会有所帮助

请帮我查一下密码。也可以从iPad多媒体资料中获取图片。

对于iPad，请添加代码：

（在

let actionSheetController:UIAlertController=UIAlertController（标题：nil，消息：nil，首选样式：.actionSheet）下）

行）

希望它能帮助你……

self。你的视图意味着你的按钮所在的区域是什么。你可以写self.view@谢谢你，我用了我的
contentView
来代替
yourView
嘿，请给我一个建议，我正在用xcode ios 13.02版制作应用程序，但我想在iPad OS 11.0版中测试这个应用程序，并在apple开发者帐户中添加它的UDID。有可能吗？？can应用程序将安装在iPad操作系统11.0版中是的，您应该将带有iOS 11的iPad添加到您的模拟器中。
actionSheetController.popoverPresentationController?.sourceView = self.yourView
