Welcome to the SimpleCoreData wiki!

How to install:

(0. Create Project with CoreData)

1. Copy category "NSManagedObject+Data" in your Project (Download Link)

2. If you have a .pch file, you can import the category there

3. DONE :-)

How to use it:

in your ViewController class:

(if category is imported by precompiled header file you only need to import your entity class ... else import the category "NSManagedObject+Data" too.

import "MyCustomEntity.h" import "NSManagedObject+Data.h"

-(void)methodFoo {

     //get all entities of MyCustomEntity
     NSArray *myCostumEntities = [MyCustomEntity allEntitiesWithSortDescriptors:nil];

     //create a new entity in db
     MyCustomEntity *newOne = (MyCustomEntity*)[MyCustomEntity createEntity];

     //delete a entity
     [newOne deleteEntity]; 
     // or 
     [MyCustomEntity deleteEntitiesWithPredicate:[NSPredicate predicateWithFormat:@"name = %@",newOne.name]];

}
