Saving data in iPhone app (revMobile)

[ukaussie]

How might i go about saving data before the app quits? and then loading the data again the next time the app opens?

Hi ukaussie,

check the PDF that came with the latest alpha (6 or 7?) for the different "specialfolderpath()" codes supported on the iPhone.

Hi Klaus,

I've read the PDF but it is not clear how to transform that information into actual code. I've tried setting the code to the below (for saving and retrieving, respectively), but it doesn't work.

Code: Select all

put tResultsField into URL "file:/home/documents/saveddata.txt"

Code: Select all

put URL "file:/home/documents/daveddata.txt" into field "resultsField"

Do i have the path correct? They recommend saving data to the 'documents' folder within the iPhone app bundle. If i have the path correct do i have the syntax incorrect?

Hi Grant,

use the "specialfolderpath()" function!

...
## I would recommend to create a folder for your app in that folder first.
## This way ther is no danger that a file named "saveddata.txt" already exists!
put tResultsField into URL("file:" & specialfolderpath("documents") & "/saveddata.txt")
...

   repeat with tVarNum = 1 to 11
      write gConfigArray[tVarNum] & CR to file lConfigFile 
   end repeat
   close file lConfigFile
end fSaveConfigFile

function fReadConfigFile
   --Read Configuration File
   put specialFolderPath (documents) & "/Config.txt" into lConfigFile
   open file lConfigFile for read
   repeat with tVarNum = 1 to 11
      read from file lConfigFile for 1 line
      put it into gConfigArray[tVarNum]
