ios - UIImagePickerController 在相机胶卷中打开

Question

是否可以直接使用 UIImagePickerController 打开相机胶卷，但仍然有返回相册列表的按钮？

UIImagePickerControllerSourceTypeSavedPhotosAlbum 将只打开相机胶卷，没有滑回相册的选项。

Answer 1

不幸的是，答案是——这是不可能的。至少不通过任何标准接口(interface)。可能会进行一些 View 层次结构挖掘或方法混合来实现它，但随后您可能会与 App Store 提交审查发生冲突。

来自Camera Programming Topics of iOS (粗体强调我的):

Instead of using the camera as the media source, you use the Camera Roll album or Saved Photos album, or the entire photo library.

并且:

Source type To configure the picker for browsing saved media as opposed to capturing a new picture or movie, set its sourceType property to one of the saved photo sources:

Use UIImagePickerControllerSourceTypePhotoLibrary to present a browser that provides access to all the photo albums on the device, including the Camera Roll album on devices that have a camera.

Use UIImagePickerControllerSourceTypeSavedPhotosAlbum to present a browser that restricts access to the Camera Roll album on devices that have a camera, or to the Saved Photos album on devices that don’t.
