HYORMDB

model到数据库的映射，大多数情况下，无需自己操作数据库。新增表只需新增model加入到tablefactory、删除表只需从tablefactory中移除、修改表只需要修改项目中的Model就可以。目的是尽量做到app的升级或因业务导致的model数据修改，而不用修改数据库相关的代码。

###Purpose

HYORMDB is a simple ORM framework,with HYORMDB you just need to deal with your model.

To use HYORMDB.

+ (void)createTablesWillUpdate:(void (^)(BOOL willUpdate))willUpdate FinishCallback:(void (^)(BOOL success))block {
   NSArray *DBTableArray = @[
       [TestCarModel class],
       [TestAnimalModel class],
   ];
// ...
}


- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
   
   [HYTableFactory createTablesWillUpdate:^(BOOL willUpdate) {
       if (willUpdate) {
           NSLog(@"数据库将进行升级");
       } else {
           NSLog(@"数据库无需进行升级操作");
       }
   } FinishCallback:^(BOOL success) {
       NSLog(@"数据库已建立");
       
       TestAnimalModel *animal = [[TestAnimalModel alloc] init];
       animal.name = @"狮子";
       animal.legs = @(4);
       animal.speed = @(50);
       animal.wikiurl = [NSURL URLWithString:@"https://zh.wikipedia.org/wiki/%E7%8B%AE"];
       [animal save];
       
       TestCarModel *car = [[TestCarModel alloc] init];
       car.name = @"hongqi";
       car.compnay = @"hongqi";
       car.model = @"hq1";
       car.picture = [NSURL URLWithString:@"http://www.faw-hongqi.com.cn/"];
       [car save];
       
   }];
   
   return YES;
}

#Access data from DB
- (void)viewDidLoad {
   [super viewDidLoad];
   
   TestCarModel *car = [[TestCarModel alloc] init];
   car.name = @"hongqi";
   NSArray *cars = [car hy_getDBModel];
   NSLog(@"数据库中共有 %ld 个名为 %@ 的car",[cars count],car.name);
   
   
   car = [car hy_getDBFirstModel];
   NSLog(@"\ncar:name = %@, \nmodel = %@, \npicture = %@, \ncompnay=%@\n",car.name,car.model,car.picture,car.compnay);
   
   TestAnimalModel *animal = [[TestAnimalModel alloc] init];
   animal.name = @"狮子";
   NSArray *animals = [animal hy_getDBModel];
   NSLog(@"数据库中共有 %ld 个名为 %@ 的animal",[animals count],animal.name);
   
   animal = [animal hy_getDBFirstModel];
   NSLog(@"\nanimal:name = %@, \nlegs = %d, \nspeed = %@, \nspeed=%@\n",animal.name,[animal.legs intValue],animal.speed,animal.wikiurl);
}
