真的没有办法从照片库中检索照片的原始文件名吗？

Question

I found some interesting topics, such as : - How to get a photo's original filename in iOS? or : - Retrieving a filename for an ALAsset

but it says that you can read the local filename of the picture, but not the original name from the source image. Indeed, on ios, the pictures are renamed to :

/var/mobile/Media/DCIM/XXXAPPLE/IMG_XXXX.JPG ou .PNG

but when I sync my phone, itunes knows which pictures are already synced, so there must be a link between the original filename and the new ?

Answer 1

纯粹是推测：iTunes可能既知道原始文件名，也知道iOS设备上使用的“同步”文件名，而iOS仅知道本地名称，这将使得无法在iOS设备上检索原始文件名。

Answer 2

iOS tries to be different than many OSes in that it does not push the abstraction of content into filesystem (files, filenames, folders and so on). In some situations it might be better to continue on this path.
