DataWrapper is a simple Objective-C ORM. The only real configuration after adding it to your project is to tell DataWrapper.m what database to use:
NSString *db= @"your_database.sqlite";
Note that each table's primary key needs to be 'key' not 'id' in order to avoid reserved word collisions.
Example usage:
CREATE TABLE Customers(
key integer primary key autoincrement,
name text,
address text,
city text,
state text,
);
CustomerData.h:
#import <Foundation/Foundation.h>
#import "DataWrapper.h"
@interface CustomerData : DataWrapper
{
NSString *name;
NSString *address;
NSString *city;
NSString *state;
}
@property (retain) NSString *name;
@property (retain) NSString *address;
@property (retain) NSString *city;
@property (retain) NSString *state;
@property (retain) NSString *zip;
@end
CustomerData.m:
#import "CustomerData.h"
@implementation CustomerData
@synthesize name, address, city, state;
+(NSString) get_table
{
return @"Customers";
}
- (id) init
{
self.fields= [[NSMutableArray alloc] init];
[self.fields addObject: @"name"];
[self.fields addObject: @"address"];
[self.fields addObject: @"city"];
[self.fields addObject: @"state"];
return [super init];
}
@end
Now in your controller you can do things like:
CustomerData *cd= [[CustomerData alloc] init];
cd.name= @"Andrew";
cd.city= @"Portland";
cd.state= @"OR";
[cd save];
NSMutableArray *results= [CustomerData find:@"state" withValue:"OR"];
