.mov文件

Question

我正在使用UIImagePickerController，这对于使用iPhone相机制作的图像效果很好，但info[UIImagePickerControllerOriginalImage]始终为nil用于使用iPhone相机创建的电影（.mov）

选择器出现在这里：

self.imagePicker.sourceType = .photoLibrary
if let mediaTypes = UIImagePickerController.availableMediaTypes(for: .photoLibrary) {
    self.imagePicker.mediaTypes = mediaTypes
}
self.present(self.imagePicker, animated: true, completion: nil)

这里是简单的UIImagePickerControllerDelegate实现：

extension MyTableViewController: UIImagePickerControllerDelegate {
    public func imagePickerController(_ picker: UIImagePickerController,
                                      didFinishPickingMediaWithInfo info: [String: Any]) {
        // ...
        print(info[UIImagePickerControllerEditedImage]) 
            // prints nil
        print(info[UIImagePickerControllerOriginalImage]) 
            // prints nil for .mov files
        print(info[UIImagePickerControllerMediaURL]) 
            // prints the correct file url in file://var/.../*.mov
}

我使用的是真正的设备，iOS11.2。
