使用sqlite3数据库与ios8应用程序使用Xcode 6和swift [英] using an sqlite3 database with an ios8 app using Xcode 6 and swift

问题描述

我对编程很新。我正在使用Xcode 6和swift来构建iOS 8应用程序。我的应用程序有很多数据，我使用firefox添加组织成sqlite3文件。我已将这些文件放入我的项目文件夹中。他们的扩展名是.sql现在我需要在我的应用程序中访问该数据。我已经通过在构建阶段选项卡中添加libsqlite3.dylib来链接sqlite3库。现在我想写代码来访问数据库。我已经使用objective-c在iOS 7及更早版本的代码和示例中在线发现了大量信息，但iOS 8和swift没有。如果有人可以帮助我或带领我朝着正确的方向前进，我将不胜感激。谢谢。

i'm fairly new to programming. I am working with Xcode 6 and swift to build an iOS 8 app. my app has quite lot of data which i have organised into sqlite3 files using the firefox add on. i have dropped these files into my project folder. their extension is .sql now i need to access that data in my app. i have already linked the sqlite3 library by adding libsqlite3.dylib in the build phases tab. now i want to write the code to access the database. i have found a lot of information online with code and examples from iOS 7 and earlier using objective-c but nothing with iOS 8 and swift. if anybody can help me or lead me in the right direction i would be grateful. thanks.

推荐答案

你可以使用sqlite.swift框架来实现与swift
的数据库连接这里是链接 https://github.com/stephencelis/SQLite.swift/blob/master/ Documentation / Index.md

you can use sqlite.swift framework to implement database connection with swift here is link https://github.com/stephencelis/SQLite.swift/blob/master/Documentation/Index.md

以下是连接sqlite数据库的示例

Here is example to connect sqlite database

 var db : Database!
var cat = Expression<String>("ZCATEGORY")
var name = Expression<String>("ZNAME")
var user : Query!
var stmt : Query!
var data : Array<Row>!

@IBOutlet var tabe: UITableView!
override func viewDidLoad() {
    super.viewDidLoad()


    createdb()
}



 internal func createdb()
{
  // bundle database  within your app
  let path = NSBundle.mainBundle().pathForResource("db", ofType: "sqlite")
    println(path)
    db = Database(path, readonly: true)
    // ZFOOD is table name
    user = db["ZFOOD"]
    println(db)
    // select distinct(cat) from ZFOOD
    stmt = user.select(distinct : cat)
    // Stored query result in array
     data = Array(stmt)

   }

func numberOfSectionsInTableView(tableView: UITableView) -> Int {
    return 1
}

func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {

    return data.count

}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {


    let cell: AnyObject = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath)
     cell.textLabel.text = data[indexPath.row][cat]
    return cell as UITableViewCell
}
