Image image returned by iPhone ALAsset with a real image on the computer

I want to store some data about an iOS photo, and then refer to this photo when it syncs with the computer.

However, I cannot figure out how to identify it in the same photograph. ALAsset does not seem to give me the original file name, and the metadata does not provide an identifier, such as a serial number from the camera.

Does anyone know how to get around this? I could print a photo, but it is a lot of calculations on the iOS device!

ideas:

  • somehow get the file name from ALAasset
  • somehow use the ALAsset URL so that I can read it on the computer
  • somehow save the data associated with the original file, which makes its way to the computer.
  • somehow save the data so that the saved version includes the original file name
  • use timestamp and some other data (crash for RAW)
  • print the first MB or so
  • find the best metadata scanner

Note that raw is even worse - iOS does not extract any metadata from it at all.

u can use evaluation bytes. that will give an original image. you cannot get the file name. if you find some other solution, share this.
