This is a lightweight ActiveRecord way of managing Core Data objects.
The syntax is borrowed from Ruby on Rails.
And yeah, no AppDelegate code.
It's fully tested with Kiwi.
- Install with CocoaPods or clone
#import "ObjectiveRecord.h"in your model or .pch file.
Person *john = [Person create];
john.name = @"John";
john.save;
john.delete;
NSDictionary *attributes; // assume it's populated with name = john, key = value,...
[Person create:attributes];
// the same thing
[Person create:@{ @"name" : @"John", @"age" : @12, @"member" : @NO }]; // XCode >= 4.4NSArray *people = [Person all];
NSArray *johns = [Person where:@"name == 'John'"];
Person *johnDoe = [Person where:@"name == 'John' AND surname = 'Doe'"].first;
// XCode >= 4.4
NSArray *people = [Person where:@{ @"age" : @18 }];
NSArray *people = [Person where:@{ @"age" : @18,
@"member" : @YES,
@"state" : @"NY"
}];NSManagedObjectContext *newContext = [NSManagedObjectContext new];
Person *john = [Person createInContext:newContext];
Person *john = [Person where:@"name == 'John'" inContext:newContext].first;
NSArray *people = [Person allInContext:newContext];If you've added the Core Data manually, you can change the custom model and database name on CoreDataManager
[CoreDataManager instance].modelName = @"MyModelName";
[CoreDataManager instance].databaseName = @"custom_database_name";// find
[[Person all] each:^(Person *person) {
person.member = @NO;
}];
for(Person *person in [Person all]) {
person.member = @YES;
}
// create / save
Person *john = [Person create];
john.name = @"John";
john.surname = @"Wayne";
john.save;
// find / delete
[[Person where: @{ "member" : @NO }] each:^(Person *person) {
[person delete];
}];
