项目介绍：

github连接 https://github.com/masong2012/DBAssistant

Getting started

add pod ‘DBAssistant’ to your Podfile
run pod install
import “NSObject+DB.h”
Example

create a file user.h

@interface User : NSObject
@property (strong, nonatomic) NSString *name;
@property (assign, nonatomic) CGFloat height;
@property (assign, nonatomic) NSInteger num;
@end
use the User model where you need

//create a new model
User *user = [[User alloc]init];
user.name = @”mason”;
user.height = 180.23;
user.num = 123456;
[user saveModel];

NSLog(@”users count: %ld”,User.allModels.count);

//find model
user = [User firstModelWhere:@{DBRowId: @(1)}];
NSLog(@”name %@,num: %ld,height: %lf”,user.name,user.num,user.height);

//update model
[user updateModel:@{@”name”: @”Dear”}];

user = [User firstModelWhere:@{DBRowId: @(1)}];
NSLog(@”name %@,num: %ld,height: %lf”,user.name,user.num,user.height);

//delete model
[user deleteModel];
NSLog(@”users count: %ld”,User.allModels.count);
