How to receive sharing content in my app?

I would like to add my app to the UIActivityViewController in other apps. How can I add/register my app to allow other apps to send content to my app? How should I receive this content?
Thank you very much to all of you that answered to my question.
With your answers I realized I have to use a Shared Extension. I have found a really nice video that explains how I have to handle the received information: https://www.youtube.com/watch?v=TBC2m8BbcCE. Maybe it could be useful for somewhere in the future.
In your Xcode project, go to file > new > target and select "Share Extension".
Your Share Extension is the extension that will provide an option in the share sheet inside other apps.
To learn more about share extensions, check out Apple's guide.

How to put file manually to iOS persistentDataPath?

{to the point}
So I want to create some Quiz Game on Unity that the questions data using external file (in this case I using JSON). I want to keep my questions data can access/edit by myself separately. And then I just have to copy-paste it manually to persistentDataPath in iOS but I don't know how to do it. Anyone can help me?
Note : I don't wanna use any script/code to do it, just manually Copy-Paste it...\
thank you,
You need to set "Application Supports iTunes file sharing" key in the info plist of your app in Xcode.
...and then you can access persistentDataPath through iTunes.
(In the example screenshot below I copied midi.csv from my MacBook to excel in my iPad)
To make it more comfy add a PostProcessBuild-script like this one (gist).
It applies the setting after each build, so no manual steps.

Writing to a file in my iOS app

I have an app that downloads files that need to be edited and submitted back to the server through the app. These files could be anything, but are most likely to be .docs. I want to be able to open and edit these files in another app on the device, such as a .doc editor.
I've been able to get this functionality to work in similar Android and Chrome apps, but I'm very new to iOS so I'm not sure what my options are.
Is there a way to give permission for another app to edit a file that is in my app's sandbox? If not, is there a way to get the file back for submittal (like finding it through a file explorer launched through my app - similar to an 'Open..." file explorer dialog used in Windows/Mac OS/Chrome)? Am I going to have to create a way for the editor app to share the edited file back to my app?
Thanks in advance for your help!
To manage the file and the paths take a look at the documentation for NSFileManager:
https://developer.apple.com/LIBRARY/mac/documentation/Cocoa/Reference/Foundation/Classes/NSFileManager_Class/Reference/Reference.html
I usually write using NSFileHandle for reading and writing:
https://developer.apple.com/library/mac/documentation/Cocoa/Reference/Foundation/Classes/NSFileHandle_Class/Reference/Reference.html
Hope this helps.
iOS8 will provide methods to allow apps to co-operate with "extensions".
See "Creating Extensions for iOS and OS X, Part 1 & 2` in the WWDC14 videos.
Also see the Apple "App Extension Programming Guide".
I ended up sending the file to a 3rd party app for editing and then sending the file back from the 3rd app to my app.

Generate .ics file on iOS

I'm building ios application that must generate .ics file from iPhone Calendar, but can't found solution for it. As I see EventKit Framework doesn't give this functionality, maybe some other frameworks/libs can do it?
Please find link here for a project which perform this. But i haven't tested
