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")
...

open file lConfigFile for write
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
