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

Question

我有一个 View Controller ，它需要能够从相册和相机中选择图片。对于 didFinishPickingMediaWithInfo 我只能有 1 个委托(delegate)方法，虽然我可以判断它是否是图像，但我似乎无法判断它是来自相册还是来自相机(我需要先将其保存在相册中)。信息中有什么可以帮助我区分这两者的吗？

谢谢...

因为UIImagePickerController传递给方法，你所要做的就是:

- (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
  }
}
