UIImagePickerController有时会显示空白，并显示控制台错误，提示您连接到com.apple.mobileslideshow.photo-picker.viewservice

Question

连续拾取许多图像时，UIImagePickerController将显示空白（白色弹出框），并打印以下控制台消息：

  

UIImagePickerController UIViewController创建错误：错误   域= NSCocoaErrorDomain代码= 4097“连接到名为服务   com.apple.mobileslideshow.photo-picker.viewservice“   UserInfo = {NSDebugDescription =连接到名为的服务   com.apple.mobileslideshow.photo-picker.viewservice}

来源：

let imagePickerController = UIImagePickerController()
imagePickerController.sourceType = UIImagePickerController.SourceType.photoLibrary
imagePickerController.allowsEditing = false
imagePickerController.delegate = self

imagePickerController.modalPresentationStyle = .popover
        imagePickerController.popoverPresentationController?.barButtonItem = self.addButton

self.present(imagePickerController, animated: true, completion: nil)

通常，如果我再次打开UIImagePickerController，它将正常工作。

任何线索是什么问题？
