magicalrecord

问题 I just started using MagicalRecord, and this might be a stupid question, but it's really bothering me... I am using MagicalRecord with sqlite, and when I initiate MagicalRecord, I used [MagicalRecord setupCoreDataStackWithStoreNamed:@"OrderSystem.sqlite"]; and it produced the following messages: 2012-10-16 16:54:48.966 OrderSystem[4135:c07] +NSManagedObjectContext(MagicalRecord) MR_contextWithStoreCoordinator: -> Created : Context * MAIN THREAD * When I tried to store my entity with the

问题 I have questions with relationships. I have to NSManagedObject classes Team and Player. Team can contain many players. Player can contain only one team. Here is the JSON from the two requests: /team { "id" : 1, "name" : "Chicago Bulls", "city" : "Chicago" }, { "id" : 2, "name" : "Detroit Pistons", "city" : "Detroit" }, ... /players { "id" : 1, "name" : "D.J. Augustin", "teamId" : 1 }, { "id" : 2, "name" : "Carlos Boozer", "teamId" : 1 }, ... Setup xcdatamodeld entities Team Entity atribute |

问题 This is the code, I save the model via Magical Record: MagicalRecord.saveWithBlock({ (localContext) -> Void in var localNotification = CDNotification.MR_findFirstByAttribute("notificationID", withValue: notification.notificationID, inContext: localContext) as CDNotification localNotification.readNumber = NSNumber(bool: true) }) Delete is called instead of update after the code above is called: func controller(controller: NSFetchedResultsController, didChangeObject object: AnyObject,

问题 Turning MagicalRecord logging off requires a #define to be made before it is first included in the project, but in the case of a project managed by Cocoapods I have no access to add a #define in the Pods project. How do I turn logging off completely in this scenario? Took me a few hours to figure out a way to do it, posting here in the hope it will help others. EDIT: this is not a duplicate as it discusses turning logging off under Cocoapods 回答1: You can use a post_install hook to modify

问题 I have an issue with CoreData persistance (MagicalRecord 2.2, iOS 7.x) Main object can be created and used on any thread: - (Collection *)collection { if (!_collection) { [MagicalRecord saveWithBlockAndWait:^(NSManagedObjectContext *localContext) { _collection = [Collection MR_createInContext:localContext]; _collection.creationDate = [NSDate date]; _collection.collectionDescription = @""; _collection.name = [CollectionHelper getNameForUnnamedCollection]; }]; } return _collection; } In any

问题 I am getting an exception with MagicalRecord version 2.0.7 whenever I launch the app, it crashes with this exception: *** Assertion failure in +[NSManagedObjectContext MR_defaultContext] I am configuring coredata like this: In appdelegate didFinishLaunchingWithOptions method: [MagicalRecord setupCoreDataStack]; In appdelegate applicationWillTerminate: [MagicalRecord cleanUp]; I noticed the crash occurs only when I try to truncate all records from an entity: NSManagedObjectContext

问题 I m using Magical Record for saving my data. This data needs encryption, so i m trying to combine it with SQLCipher library(http://sqlcipher.net/ios-tutorial/). I already setup SQLCipher and tested it with Core Data successfully, using EncryptedStore file from this example https://github.com/project-imas/encrypted-core-data: What i did was only changed NSPersistentStoreCoordinator like this: NSPersistentStoreCoordinator *coordinator = [EncryptedStore makeStore:[self managedObjectModel]:

问题 I'm trying to use MagicalRecord with a data model in a static library. When I just call [MagicalRecord setupCoreDataStackWithAutoMigratingSqliteStoreNamed:@"db.sqlite"]; in the library, it doesn't seem to load the data model. A call to [TheObject MR_createEntity]; will throw an exception: could not locate an entity named 'TheObject' in this model.' How do I load the model I want to use? An overview of the project layout: I figure MR tries to load the model from the main bundle by default?

问题 Currently in a given method within a given class I can create a instance of a custom variable managed by Core Data and Magical Record with the following line AViewController.m List *list = [List MR_createInContext:_managedObjectContext]; I can then set the list's properties like so: list.name = @"FooBar Name"; My question : In AViewController.h can I do the following - @interface AViewController : UIViewController { /* Define Local List Var for AViewController class */ List *list; } Then in

问题 I have a table that stores some data. Let's say data is too big to load into memory all at once. I want to show this data in UItableView. -(NSInteger) numberOfSectionsInTableView:(UITableView *)tableView { return 1; } -(NSInteger) tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return [Item MR_numberOfEntities]; } -(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { UITableViewCell *cell = [tableView
