I'm trying to save data to an SQLite database on one card, then on another card retrieve this information and display it in reverse entry order.
Everything is working great on the desktop, but on iOS I get one of two problems:

1) If I attempt to create the database in the specialfolderpath("documents") directory on first run the app cannot find the database.
2) If I attempt to load a database that has been copied into the app at build I get an error for trying to write to a read only database.

If someone could take a look and suggest a solution... I'm sorry my code has so many commented out portions, but I'm pretty new to this and I've been trying different things all evening.
Really frustrating that this works on desktop perfectly then bugs as soon as it hits the simulator or an iphone.

Thanks.

Hey Observ3

I know first hand how frustrating this can be. You might try this code, it isn't SQLite but it does save a stack effectively and it's simple.
Put this in a button on the first stack...

Code: Select all

on mouseUp
 open stack "Level Select"
      
     if the environment is "mobile" then
      put (specialFolderPath("Documents") & "/Level Select.livecode") into tPathToDatabase
      put (specialFolderPath("engine") & "/Level Select.livecode") into tPathToStartLoc
      
      try
         if not (there is a file tPathToDatabase) then
            put url ("binfile:" & tPathToStartLoc) into temp
            put temp into url ("binfile:" & specialfolderpath("Documents") & "/Level Select.livecode")
            wait 5 milliseconds with messages
         end if
      catch pErr
         put pErr into field 1
      end try
      try
         go stack tPathToDatabase
      catch pErr
         put pErr into field 1
      end try
   end if
end mouseUp

Just get rid of the words "Level Select" and use the name of the second stack. You do need two stacks for this, the first one that pops up won't be saved but it will save the next stack that opens.

Put this into the stack script of the other stack...

Code: Select all

on shutDown
save this stack
end shutDown

I hope this helps. Let me know if you get confused.

Thanks Danny. I don't think that will work for this application, but I will certainly add it to my bag of tricks.
Still hoping someone out there has figured out the black magic of mobile SQL...
