Bugfix 2012-08-16: Removed a dependency to a custom library.

Mac Os X Sqlite Library

This is a very simple thread safe SQLite wrapper for Mac OS X and iOS development.

It is a singleton, so it allows for a single database connection. That being said, the library is threadsafe and if multiple threads attempt to do SQL operations, they will be queued up until the currentthread is done (i.e. the database transaction is committed).

It has support for transactions and uses blocks.

Data skeleton and data locations

Before using the library you have to set the name of your preferred database file and it's location.

After setting the file name, the code below will copy the file data_skeleton.sqlite3 to the file you specified above.Note that this will NOT override the file, UNLESS you specify YES as the ForceReset parameter.

setDatabaseFileInCache

The cache location will store the database in a cache folder and this folder can be deleted at any timewhen the application is not running. It is also not backed up.

Use this for databases that store temporary data that you will not need to store between application launches.

setDatabaseFileInDocuments

The documents location will store the database in the user's Documents folder. This folder is persistentand will not be deleted unless the user uninstalls the iOS application or manually deletes the file on Mac.

Use this for databases that store persistent data such as user profiles or game highscores.

The performQuery: method returns different integer values depending on the query:

  • INSERT returns the id of the last inserted row
  • UPDATE returns the number of affected rows
  • SELECT returns number of found rows

Using transactions

By default every query is performed in it's own transaction, however if you are performing lotsof insert queries using transactions increases performance quite a bit.
