安装

JLCoreDataHelper 通过 CocoaPods 提供。要安装它，只需将以下行添加到您的 Podfile 中

pod "JLCoreDataHelper"

开始之前

1. 创建数据模型文件。(.xcdatamodeld)
2. 按照您的要求设置实体和属性。
3. 在应用启动时执行以下代码。推荐在 application:didFinishLaunchingWithOptions: 方法中执行此操作。

#import <JLCoreDataHelper/JLCoreDataHelper.h>
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    [JLCoreDataHelper initializeWithDataModelName:@"Data Model file name here" saveFolderName:@"folder name"]; 
}

1. 可以选择将存储类型设置为特定的实体，如以下示例所示

[JLCoreDataHelper setStoreType:JLCoreDataStoreTypeMemory forEntity:@"Entity Name"];
