SQLite轻量级数据库在移动应用中使用非常普遍,但是目前的库是C编写的,为了方便使用,对SQLite相关的操作用Swift进行了封装。这个封装代码使用了一个开源项目SQLiteDB,地址是:https://github.com/fahimf/sqlitedb

当前,SQLiteDB库已经升级至Swift3

下面通过一个阳历展示SQlite数据库连接,创建表,查询数据,插入数据,删除数据等操作

1、当输入用户名和手机号,点击保存即可将数据存入数据库

2、下次启动,自动从数据库中载入初始化信息

操作步骤:

1)和oc一样,需要在Build Phases -> Link Binary With Libraries中点击加号,添加libsqlite3.0.tdb到项目中来

2)创建连接文件Bridging-Header.h,并导入sqlite3的头文件

3)在项目编译属性引用头文件

4)导入SQLiteDB的代码(SQLiteDB.swift、SQLTable.swift和String-Extras.swift),注意:最好是复制到工程里面,然后add进去,这样的话,不容易报错,不要直接拖!

5)核心代码如下:

import UIKit

class ThirtyViewController: UIViewController {

    var db:SQLiteDB!

    @IBOutlet weak var telTF: UITextField!
@IBOutlet weak var userTF: UITextField!
@IBOutlet weak var saveClick: UIButton!
@IBOutlet weak var activityClick: UIButton! override func viewDidLoad() {
super.viewDidLoad() //获取数据实例
db = SQLiteDB.sharedInstance //如果表还不存在则创建表(其中uid为自增主键)
let result = db.execute(sql: "create table if not exists t_user(uid integer primary key,uname varchar(20),mobile varchar(20))")
print(result) //如果有数据则加载
initUser() } //点击保存
@IBAction func SaveClick(_ sender: Any) { saveUser() } //从SQLite加载数据
func initUser() {
let data = db.query(sql: "select * from t_user")
if data.count > {
//获取最后一行数据显示
let user = data[data.count - ]
userTF.text = user["uname"] as? String
telTF.text = user["mobile"] as? String } }
//从SQLite删除数据
@IBAction func delegateClick(_ sender: Any) { let data = db.execute(sql: "delete from t_user where uname='Jason1'")
print("data is \(data)") } //保存数据到SQLite
func saveUser() {
let uname = self.userTF.text
let mobile = self.telTF.text //插入数据库,这里用到了esc字符编码函数,其实是调用桥接文件实现的
let sql = "insert into t_user(uname,mobile) values('\(uname)','\(mobile)')" print("sql:\(sql)") //通过封装的方法执行sql
let result = db.execute(sql: sql)
print(result) } }
