        /*创建*/
        let admin = Admin.MR_createEntity()//创建
        admin?.token = "1234"//编辑
        print("创建")
        NSManagedObjectContext.MR_defaultContext().MR_saveToPersistentStoreAndWait()//保存
        /*创建结束*/

            print(a.token)
            a.token = "liuman"//编辑
            //a.MR_deleteEntity()//删除

        print("条件查询token值为liuman的")
        let liuman = Admin.MR_findFirstByAttribute("token", withValue: "liuman")
        print(liuman!.token)
        /*查询结束*/
        //Admin.MR_truncateAll()//删除所有
        NSManagedObjectContext.MR_defaultContext().MR_saveToPersistentStoreAndWait()//创建编辑删除之后都要保存，原save方法，被取代了。
        //MagicalRecord.cleanUp()//app退出前操作，关闭coredata
