如何判断 didFinishPickingMediaWithInfo 返回的图像是来自相机还是相册?

问题描述

我有一个视图控制器，需要能够从相册和相机中选择图片.我只能有一个 didFinishPickingMediaWithInfo 委托方法，虽然我可以判断它是一个图像，但我似乎无法判断它是来自相册还是来自相机(我需要先将它保存在相册中).信息中有什么东西可以帮助我区分这两者吗?

I have a view controller that needs to be able to choose a picture from the photo album and also from the camera. I can only have 1 delegate method for didFinishPickingMediaWithInfo and while I can tell if it's an image, I can't seem to tell if it's from the album or from the camera (and I need to save it in the album first). Is there anything in the info that can help me distinguish from the two?

谢谢...

推荐答案

因为UIImagePickerController 是传递给方法的，所以你要做的就是:

Because the UIImagePickerController is passed to the method, all you have to do is:

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
  if ([picker sourceType] == UIImagePickerControllerSourceTypeCamera) {
    // Do something with an image from the camera
  } else {
    // Do something with an image from another source
  }
}
