The app needs document files from users. Document files are usually found in PC / emails right? What is the most intuitive / user friendly way to get those data from your iOS app? No need to consider effort or how long it will take, the focus is in the user experience.
I have the ff ideas:
Import / Export data via email
- Read an article here. So you will ask your users to email files to him/herself and your app will get the data? Still a bit complicated, but is this the best way?
iTunes
- Drag and drop files from Desktop to your app using iTunes. Imho, not very intuitive but I could be wrong.
Provide web screen for users to upload their files to server.
- This is a bit okay, but we want to lessen Desktop / PC interaction.
Provide a server to accept files from email.
- The difference from Item #1 is you will ask user to email it to your specific email address and the server will store it and the app will connect to the server to get the files of course with all the permissions / etc. Will require significant effort, but it's not an issue, as long as it will enhance user experience.
Support other means of data sharing like Dropbox? Any other service that is best for this purpose?
[update 1] Wifi / Bluetooth file transfer from PC / other devices to iPad.
[update 2] iCloud
Did I miss anything. Thank you for your time.
