Make a file type launch your app, and get Path of file

Unity Engine

I am creating an iOS app, which handles .CSV files.

Which info.plist property do I need to add to mark CSV files as supported by my app? (So upon touching CSV files my app would launch)

Also, I need the path for the CSV file that launches my app.

I am using the OnAppliationFocus() method, but how do I get the path of the file that launched my app?

CFBundleDocumentTypes. I would google “CFBundleDocumentTypes sample” because there is a bit more involved.

Are you familiar with Objective-C programming? This may be required to do this, because you need to implement this method in your app delegate:
https://developer.apple.com/documentation/uikit/uiapplicationdelegate/1622921-application?language=obj
I would do that in combination with the following method:
https://developer.apple.com/documentation/uikit/uiapplicationdelegate/1623112-application?language=objc
You need to read from the launchOptions dictionary, and then pass that value back to Unity via UnitySendMessage.

Thanks for the reply, the CFBundleDocumentTypes example will help most certainly. But I am not familiar with NSDictionary and how I can communicate with my C# code

I have found this:

NSString * aString = [[NSString alloc] initWithString: @"a string"];
UnitySendMessage("MyObject", "Method", [aString UTF8String]);

Should I create an .m file from this? Unfortunately I am really not sure about how this works.
