set/get preference file

[maxs]

I looked but could not find.

How can I make and get a preference file for IOS?

Hi Max,

the same way as on the desktop, maybe in another folder
Read from and write to -> specialfolderpath("documents") & "/your_pref_file_here"

Thanks, Klaus,

So simple, but not so obvious for me.

It works for the Mac, but not ios.
I copied the special folder path folder with the file into the standalone prefs, but this code does nothing. Where did I go wrong?

on closecard
if the environment = mobile
then
open file specialfolderpath("myprefs") & "/PrefsMax"
write ( the number of this card ) to file "PrefsMax"
close file specialfolderpath("myprefs") & "/PrefsMax"
end if
end closecard

on opencard
global NewCardLoc
if the environment = mobile
then
if there is a file specialfolderpath("myprefs") & "/PrefsMax"
then
open file specialfolderpath("myprefs") & "/PrefsMax"
read from file "PrefsMax" at 1 until eof
put it into NewCardLoc
put it into fld "testit" of cd 2
close file specialfolderpath("myprefs") & "/PrefsMax"
end if
end if
end opencard

"myprefs" is NOT a valid "specialfolderpath", please check the dictionary if in doubt!
What's wrong with my proposal -> specialfolderpath("documents") ?

P.S.
You might want to use the shorter URL syntax:
...
put specialfolderpath("documents") & "/MinPrefs) into tPrefsFile
## Read:
put url("file:" & tPrefsFile) into fld "Wherever you want to display the prefs..."
...
## Write:
put the num of this cd into url("file:" & tPrefsFile)
...

Thank you Klaus

I really like
put the num of this cd into url("file:" & tPrefsFile)

Does that save the number into a permanent file on the ipad? I can not be sure when using the simulator.

Hi Max,

the simulator is also still a mistery to me

Yes, this will save to a "permanent" file on the device itself!

I use these three scripts to manage preferences. For example, if I want to write the value "1" to line 3 of the preferences file I call:

setPref 3, "1"

To get the value in line 3 of the preferences file I call:

getPref (3)

The writefile script simply manages the writing of the preferences file to the device.

------------

on setPref whichPref, whatValue
open file specialFolderPath("Documents") & "/prefs.txt"
read from file specialFolderPath("Documents") & "/prefs.txt" until eof
close file specialFolderPath("Documents") & "/prefs.txt"
put whatValue into line whichPref of it
writeFile "prefs", it
end setPref

function getPref lineNumber
open file specialFolderPath("Documents") & "/prefs.txt"
read from file specialFolderPath("Documents") & "/prefs.txt" until eof
close file specialFolderPath("Documents") & "/prefs.txt"
return line lineNumber of it
end getPref

on writefile fileTowrite,dataTowrite
set the defaultFolder to specialFolderPath("Documents")
put dataTowrite into URL (("file:"&fileTowrite&".txt"))
end writefile
