Data model : CoreDataManager.xcdatamodeld
Entity model : CDTestEntity
attribute : type of Entity

num : integer64
name : String

□ import header file

#import "CoreDataManager.h"

□ initialize

[CoreDataManager initSettingWithCoreDataName:@"CoreDataManager"
                                  sqliteName:@"CoreDataSqlite"];

□ insert

// create insert instance of CoreData
CDTestEntity *insertEntity = [CoreDataManager createInsertEntityWithClassName:@"CDTestEntity"];

// add value
insertEntity.num = @((uint)arc4random()%RAND_MAX);
insertEntity.name = @"test";

// save insert data
[CoreDataManager save];

□ update

// search condition
    NSPredicate *pred = [_coreDataManager setPredicateOverWithSearchKey:@"id" searchValue:@(0)];
    // fetch data
    [_coreDataManager fetchWithEntity:TEST_ENTITY
                            Predicate:pred
                              success:^(NSArray *fetchLists)
    {
        // update
        for (CDTestEntity *updateEntity in fetchLists)
        {
            updateEntity.name = @"update_test";
            [_coreDataManager save];
        }

                         success:^(NSArray *fetchLists)
{
    // parse
    for (CDTestEntity *fetchEntity in fetchLists)
    {
         // access property of fetchEnity    
    }
}
                          failed:^(NSError *error)
{
}];

□ delete

[_coreDataManager fetchWithEntity:TEST_ENTITY
                            Predicate:nil
                              success:^(NSArray *fetchLists)
