magicalrecord

问题 I got an app which stores data about restaurants. Their menu, schedule and so on. Theres ~200 restaurants in the DB by now. The app used to retrieve those places by a single shot, but it was taking too much time to load, so i decided to load the data one by one. On the start app asks the server for an array of place's ids, then get the data via API. I set completion blocks for RK's operations to background queues, but it didn't help. Scrolls are running not smoothy enough and sometimes the

问题 When someone logins my app, a call with a JSON response is made, and I use this data to import it into Core Data with MagicalRecord. After all importing is done, a block named success is called to let my LoginViewController know everything was fine, and stopping the UIActivityIndicatorView , so it can make a segue. It Segue to a new ViewController and it has a UITableView to display the freshly imported data. My problem is, that this success block is been called before MagicalRecord is done

问题 (Forgive me since I am not use to posting here. Will do my best) I am working on an iOS application that will be using a pre-populated database. In my workspace, I have a project for the iOS app and a separate command line tool project to populate the database. I have dragged the database file from the "/Library/Application Support" folder into my iOS project (without using the "Copy Items If Needed"). So when there is a change in the data or additional data is required, I can just run the

问题 I am working with MagicalRecord 2.2. Sometimes I receive 'CoreData could not fulfill a fault' crash in production code and I've created some test code to investigate this problem. Here is its description. I have an entity "Object". At the start, I create one object on main thread, then I call [MagicalRecord saveWithBlock:...] where I fetch this object from local context and delete it. I added extra logging to the method (NSManagedObjectContext+MagicalSaves.m) (void)MR_saveWithOptions:(

问题 I have a a one-to-many relationship as an NSOrderedSet on an NSManagedObject . When the addObject: method is called on the ordered set (which I'm calling from a property on an NSManagedObjectModel subclass object), however, the inverse relationship is not being set automatically. What can cause this? As a related note, I am using Magical Record to make it easier to map data to the NSManagedObject objects. Further, I've also referred to this post, but I'm not overriding these methods on my

问题 I have an app where I download the data on startup using a list of operations and it crashes randomly for unknown core data reasons so I spent few days on checking the best practices to update/fetch data in multithreading core data with MagicalRecord. One of the options was to enable the multithreading debugger -com.apple.CoreData.ConcurrencyDebug 1 where Xcode stops the apps when it violates one of their rules. So, Xcode stops my app on this line [SyncRequestEntity MR_createEntityInContext:

问题 If I create a new Custom Object in Core Date (using Magical Record) like so List *list = [List MR_createInContext:_managedObjectContext]; And then I perform various actions on it, such as setting its name list.name = @"Foobar List"; But then the user decides to cancel the creation of this list, do I need to delete? As in, is this list already in memory even though I haven't saved the local context with [localContext MR_save]; 回答1: If you create the object in the managed object context, it

问题 Simply I have an app, and today extension. Also I have two entities: Goal and Service . @objc(Goal) class Goal: NSManagedObject { @NSManaged var identifier: String @NSManaged var startDate: Date @NSManaged var endDate: Date private var services: [Service] { let predicate = NSPredicate(format: "date >= %@ && date <= %@", startDate as NSDate, endDate as NSDate) return Service.mr_findAll(with: predicate) as! [Service] } var duration: Int64 { return services.reduce(0) { $0 + $1.duration } } }

问题 I have this code: HLMReferenceData *referenceDataObj = [HLMReferenceData createEntity]; [MagicalRecord saveWithBlock:^(NSManagedObjectContext *localContext){ HLMReferenceData *localReferenceData = [referenceDataObj inContext:localContext]; // Setup localReferenceData here .... } completion:NULL]; As far as I can see this is exactly in line with the examples on the net of how to create a new record using MagicalRecord. However it does not work. I get this in the log: ... +[MagicalRecord

问题 I have a project setup using the UnitTest template provided by Apple. Too I added MagicalRecord to Prefix header. When I am running on the device and Simulator everything is working fine. Except the Unit Tests, when I am compiling for the unit tests the build failed with the following command: 'CoreData+MagicalRecord.h' file not found . This happens in the prefix header. prefix.pch // // Prefix header for all source files of the '123tv' target in the '123tv' project // #import <Availability.h
