概览
此iOS库可用于创建和管理CoreData。
演示
安装
pod 'PEAR-CoreDataManager-iOS'
用法
[示例]
数据模型：CoreDataManager.xcdatamodeld
实体模型：CDTestEntity
属性：实体的类型
id：integer64
num：integer64
name：String
- 创建数据模型 <.xcdatamodeld>
- 在数据模型中创建实体模型
- 在实体模型中创建属性和类型
- 创建实体类 <.h.m>
□ 导入头文件
#import "CoreDataManager.h"
□ 初始化
[CoreDataManager initSettingWithCoreDataName:@"CoreDataManager"
sqliteName:@"CoreDataSqlite"];
□ 插入
// 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];
□ 更新
// 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];
}
}
failed:^(NSError *error)
{
}];
□ 获取
// fetch all data
[CoreDataManager fetchWithEntity:@"CDTestEntity"
Predicate:nil
success:^(NSArray *fetchLists)
{
// parse
for (CDTestEntity *fetchEntity in fetchLists)
{
// access property of fetchEnity
}
}
failed:^(NSError *error)
{
}];
□ 删除
[_coreDataManager fetchWithEntity:TEST_ENTITY
Predicate:nil
success:^(NSArray *fetchLists)
{
// delete entity
for (CDTestEntity *deleteEntity in fetchLists)
{
[_coreDataManager deleteWithEntity:deleteEntity];
}
}
failed:^(NSError *error)
{
}];
