sending .txt file to dropbox using code (without needing to press 'sync')

edited March 2014 in Questions Posts: 143

Hello everybody,

I am creating an App for a research project. I have made an app that allows a user to draw their house plan. This house plan is written to a string which can be saved to a txt file and sent to dropbox.spritepack folder. However this txt file only updates in my real dropbox AFTER I hit 'sync' on my ipad, this is a cumbersome step and I was wondering whether there was a way to make it sync automatically or after I hit a button in my app?

Alternatively, is there a way to 'export' my houseplan txt file to a local folder in case internet connectivity is not available? - also all done in the app and not needing to manually 'sync'?

I appreciate all help I can get.




  • I have found this method which I will use for the 'online' export, but I am also looking for a 'offline' method

    @archistudent you can save to your documents folder on the ios device.

  • Cool - What is the link to the documents folder?

    Also what is the easiest way to access this folder or is there a way this automatically updates on dropbox? This app will be used all over the country and by lay persons with not much computer literacy.

    @archistudent Here's an example of writing and reading a file to/from the documents folder. The file has to have a .png extension to show up in the documents folder. It could have a .txt or other extension and it will still be there, but just not visible.

    function setup()        local file = os.getenv("HOME").."/Documents/testfile.png"     local text = "This is some sample text."     writeTest(file,text)     readTest(file) end function writeTest(file,txt)     print("writing file")     io.output(,"w"))     io.write(txt)     io.close()     print("write done") end function readTest(file)     print("reading file")     io.input(,"r"))     for i in io.lines() do         print(i)      end     print("read done") end
