How to receive a mix of different application defined type files through air drop

  1. I cannot define my application defined type files like .AAA and .BBB

  2. and I can air drop multiple .AAA files or multiple .BBB files to my iPhone and use my application to received these files.

  3. but if I mix .AAA and .BBB files and air drop them to my phone. My phone always prompts " cannot receive all these items at once.

So, how to receive a mix of my application defined type files through air drop?

thanks

My bad, a typo, 1. I CAN define my application defined type files like .AAA and .BBB

I still don't know how directly solve this issue, but found a work-around, basically, add addition file type like, .CCC, and combine. .AAA.CCC. and .BBB.CCC to represent type A and type B files that are defined by my application. when sending a mix of type A and type B files, the files are like. (.AAA.CCC , .BBB.CCC, .AAA.CCC and etc.) and in my app, when importing files, will treat. .AAA.CCC and .BBB.CCC files differently.
