Just don't share a single instance across threads, and definitely not across multiple threads at the same time. 17 | 18 | Instead, use `FMDatabaseQueue`.

So if you call `FMDatabaseQueue`'s methods from multiple threads at the same time, they will be executed in the order they are received.

3 | 因为项目中主要是多线程中操作数据库，所以Demo里都是多线程操作的方式，该类也可以在主线程中使用。
4 | 依赖FMDB，支持ARC和非ARC。
5 | 不需要实体与数据库映射的属性，添加到transients数组即可。
6 | #怎么使用？ 7 | 将项目中DBModel和FMDB两个文件夹拖进工程，然后添加libsqlite3.dylib库。
8 | 创建自己的实体类，继承JKDBModel即可。
9 | 例如User 继承自DBModel，然后可以直接直接调用 User对象的CURD操作。

3 | 封装类的数据库操作思路与多数FMDB封装不同，是直接实体类对象来做增、删、改、查。
4 | 代码中有比较详细的注释和讲解，有助于理解runtime的机制，如果能帮到你，麻烦给一个`star`。 5 | 对原作者的框架反射部分做了简化，便于理解，原作者的源码github地址在本文尾部。 6 | 7 | # 为什么要封装这个类呢？ 8 | 原项目使用的是sqlitepersistentobjects，多线程处理时，问题比较多
9 | 多数FMDB框架功能比较多，代码量也比较大，但是很多功能不常用，而且也不便于理解，因此我考虑用简单易于理解的方式
10 | 来封装一个适用于公司项目的轻量级小框架。
11 | 因为项目需要在多线程下操作数据库，所以demo中的使用案例多数是多线程操作，但是单线程操作也适用。 12 | 13 | # 特点 14 | 改进后的特点如下：
15 | 1.自动创建数据库、自动创建数据库表。
16 | 2.自动检测字段添加新字段。
17 | 3.一行代码实现数据库的CURD操作。
18 | 4.源码及其简单，易于理解和掌握。
19 | 5.扩展自己的功能也非常得简单，容易。
20 | 6.支持多线程，非线程阻塞。
21 | 7.支持arc和mrc。
22 | 23 | # how 怎么使用JKDBModel 24 | 使用JKDBModel非常的简单，只需要将FMDB和DBModel拖入项目中，然后添加`libsqlite3.dylib`
25 | 然后让你的实体类继承自JKDBModel，你的实体类就具备了操作数据库的功能。 26 | 27 | # demo中有CURD演示操作 28 | 效果图
29 | ![](http://cc.cocimg.com/bbs/attachment/postcate/topic/16/313017_189_ccde14372754000f44c3edbcc68c9.png "CURD示例") 30 | 31 | ## CURD操作 32 | 操作都有保存和批量保存两种方式。
33 | 例如
34 | 保存操作：`[user save]`
35 | 批量保存：`[User saveObjects:array]` 36 | 37 | # 数据库操作api 38 | ```Objective-C 39 | /** 数据库中是否存在表 */ 40 | + (BOOL)isExistInTable; 41 | /** 保存或更新 42 | * 如果不存在主键，保存， 43 | * 有主键，则更新 44 | */ 45 | - (BOOL)saveOrUpdate; 46 | /** 保存单个数据 */ 47 | - (BOOL)save; 48 | /** 批量保存数据 */ 49 | + (BOOL)saveObjects:(NSArray *)array; 50 | /** 更新单个数据 */ 51 | - (BOOL)update; 52 | /** 批量更新数据*/ 53 | + (BOOL)updateObjects:(NSArray *)array; 54 | /** 删除单个数据 */ 55 | - (BOOL)deleteObject; 56 | /** 批量删除数据 */ 57 | + (BOOL)deleteObjects:(NSArray *)array; 58 | /** 通过条件删除数据 */ 59 | + (BOOL)deleteObjectsByCriteria:(NSString *)criteria; 60 | /** 清空表 */ 61 | + (BOOL)clearTable; 62 | 63 | /** 查询全部数据 */ 64 | + (NSArray *)findAll; 65 | 66 | /** 通过主键查询 */ 67 | + (instancetype)findByPK:(int)inPk; 68 | 69 | /** 查找某条数据 */ 70 | + (instancetype)findFirstByCriteria:(NSString *)criteria; 71 | 72 | /** 通过条件查找数据 73 | * 这样可以进行分页查询 @" WHERE pk > 5 limit 10" 74 | */ 75 | + (NSArray *)findByCriteria:(NSString *)criteria; 76 | /** 77 | * 创建表 78 | * 如果已经创建，返回YES 79 | */ 80 | + (BOOL)createTable; 81 | 82 | #pragma mark - must be override method 83 | /** 如果子类中有一些property不需要创建数据库字段，那么这个方法必须在子类中重写 84 | */ 85 | + (NSArray *)transients; 86 | ``` 87 | # 更新 88 | 修改了创建表和字段检测功能方法。
89 | 由于实际项目中，一个账号对应一个文件夹放数据库，经常会有切换账号登录的需求，在initialize创建数据库表，只执行一次，数据库不能保证一定创建，因此添加切换数据库功能，动态创建功能。 2015-08-25
90 | 添加条件查询和删除的新方法：
91 | ``` 92 | + (instancetype)findFirstWithFormat:(NSString *)format, ...; 93 | 94 | + (NSArray *)findWithFormat:(NSString *)format, ...; 95 | 96 | /** 通过条件删除 (多参数）--2 */ 97 | + (BOOL)deleteObjectsWithFormat:(NSString *)format, ...; 98 | ``` 99 | 更新于2015-09-08 100 | 101 | # 提醒 102 | SQLite 默认支持五种数据类型TEXT、INTEGER、REAL、BLOB、NULL，我只做了少数类型的判断，
103 | 如：int、unsigned int、short、unsigned short、BOOL，对象类型默认是字符串。
104 | 当然你可以详细的把所有的类型判断都做出来，代码中有部分常用的表示符号，详细的可以查看apple 文档。
105 | 理解代码比会使用代码更重要，望使用的时候先理解一下实现思路。

110 | 增删改查封装思想源自：`SQLitePersistentObject`，与之前做Java时的数据库操作类似，更简易。 111 | 112 | 如果你有什么问题或者有更好的建议，请告知我，我会及时更正，修改。 113 | --------------------------------------------------------------------------------
