Question

我需要知道在didFinishPickingMediaWithInfo之前选择的mediaType才能允许根据类型进行编辑。

如果您选择视频，那么它将是真的，如果您选择图像，它将是假的。

在sourceType = .camera的情况下，我这样做了：

cameraController.allowsEditing = cameraController.cameraCaptureMode == .video

Answer 1

您可以选择mediaTypes

来执行此操作

 var imagePicker = UIImagePickerController()

适用于相机：

if UIImagePickerController .isSourceTypeAvailable(UIImagePickerControllerSourceType.camera) {
   cameraController.sourceType = UIImagePickerControllerSourceType.camera
   cameraController.allowsEditing = cameraController.cameraCaptureMode == .video

   self.present(imagePicker, animated: true, completion: nil
 }

对于来自图库的视频：您可以选择媒体类型：

cameraController.sourceType = UIImagePickerControllerSourceType.photoLibrary
cameraController.mediaTypes = [kUTTypeMovie as String]
cameraController.allowsEditing = true
self.present(imagePicker, animated: true, completion: nil)

仅适用于图片：

cameraController.sourceType = UIImagePickerControllerSourceType.photoLibrary
cameraController.allowsEditing = false
self.present(imagePicker, animated: true, completion: nil)

如何在Swift中的didFinishPickingMediaWithInfo之前知道在photoLibrary中选择的mediatype？
