Acknowledgements - people you'd like to thank for their help in producing this book, (friends, family, etc) - this part is written in the first person. I would especially like to thank my family, especially my wife who have put up with my loss of family time researching the subject matter, writing and collating it with the publisher PactIT. It has been difficult especially after completing a BSc, MSc and now an IT book. So thanks for the kind patience in this project, that I wanted to do for sometime.

iOS with SQLite

Out of the hundreds of thousands of apps in all the app stores, it would be difficult to find the one that does not require a database of some sort to store or handle data in a particular way. There are different formats of data and datafeeds, but they all require some sort of temporary or permanent storage. A small amount of data may not be applicable, but a medium or large amount of data will require a storage mechanism, such as a database to assist the app.

Using a database such as SQLite with iOS will enable developers to use their existing skills to run their DBMS. For SQLite, there is a C-library that is embedded and available to use with iOS with the Xcode IDE.

Apple fully supports SQLite, which uses an include statement as a part of the library call, but developers can also use FMDB, which is a cocoa/objective-C wrapper around SQLite.

A few advantages of SQLite are that it is fast, lightweight, reliable, uses existing SQL knowledge, is supported by Apple on Mac OS and iOS and by many developers, as well as being integrated without much outside involvement.

The SQLite 3 library is under the general tab once the main project name is highlighted on the left-hand side of the page. Then, at the bottom of the page, within Linked Frameworks and Libraries, click on the + for a modal window to appear. Enter the word sqlite and select the libsqlite3.dylib library, as shown in the following screenshot:

In effect, it is the C++ wrapper, called the libsqlite3.dylib library, within the framework section that allows the API to work with SQLite commands.

Before any SQL processes can take place, the database should be opened and ready for querying, and, upon the success of data retrieval, the constant called SQLITE_OK should be set to 0.

Once the C++ wrapper is used and the access to SQLite commands is available, it is an easier process to use SQLite with iOS.
