推荐答案

首先你需要创建你的数据库.
从命令行创建您的数据库文件.

First of all you need to create your database.
From the command line create your db file.

sqlite3 mydb.db

然后在数据库中创建表

CREATE TABLE tags (id int(5), name varchar(255), created_at datetime, updated_at datetime);

对数据库中所需的任何表重复此操作.

Repeat that for any tables that you want in your database.

然后你需要在你的项目中包含数据库文件.像添加任何其他现有文件一样，将现有数据库文件添加到您的项目中.

Then you need to include the database file in your project. Add the existing database file to your project as you would any other existing file.

接下来，您必须在框架中链接以与数据库交互.这可以在您当前的 iPhone SDK 文件夹下找到.

Next you will have to link in the framework to interact with the database. This can be found under you current iPhone SDK folder.

/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS2.2.sdk/usr/lib/libsqlite3.0.dylib

最后你必须包含来自

/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS2.2.sdk/usr/include/sqlite3.h

现在应该可以编写代码来从您的 iPhone 应用程序中访问您的 sqlite 数据库.

It should now be possible to write code to access your sqlite database from within your iPhone application.
