Tutorial: Getting Started With Core Data In iOS 5 Using Xcode Storyboards
Recently I mentioned an excellent tool for generating Core Data classes, and another popular resource for developers using Core Data is Magical Record providing a library for using Core Data utilizing the Active Record pattern. I’ve also mentioned a good tutorial for those getting started with Core Data, but with some of the recent changes, but with the release of iOS 5 there are a few issues and
Transient Entities and Core Data | Cocoa Is My Girlfriend
Core Data has many features, one of which is the Transient attribute. This type of attribute on a Core Data entity is part of a data model, but is not persisted in your Core Data persistent store. If you open up the raw SQLite store file and peek at the schema, you will not find any transient attributes. These transient attributes are still handy despite no data being persisted to the data store.
Saving JSON to Core Data | Cocoa Is My Girlfriend
Hi, I’m new here. You may know me as @atomicbird on Twitter. Just a few days ago my book Core Data for iOS: Developing Data-Driven Applications for the iPad, iPhone, and iPod touch (co-written with the excellent Tim Isted) was published, and Matt invited me to contribute some Core Data tips to CIMGF. I’m going to start off discussing taking JSON data from a web service and converting it to Core Da
Cocoaの日々: CoreData - マイグレーションを考慮した CoreDataManager パターン
CoreData を使うアプリであればこの程度の件数はすぐに行くので、起動時にマイグレーションが走ると確実に落ちてしまう。これを防ぐためには起動時に CoreData へアクセスさせないのが最低限の対策になるが、その場合でもユーザが CoreData へアクセスする操作を行った瞬間にマイグレーション処理に時間がかかって画面が固まったようになるのでユーザビリティは良くない。 マイグレーションを考慮したパターン よって CoreDataを使うアプリではマイグレーション用の画面を用意するのがベスト。処理フローはこんな感じ。 起動 ↓ (1)マイグレーションチェック もし必要なら、マイグレーション用の画面へ遷移し、(2)マイグレーション実行 ↓ 通常画面マイグレーションチェックは NSPersistentCoordinator を使えばわかる。 Cocoaの日々: [iOS][Mac] CoreD
iPhone Development: Core Data Library
Monday, April 12, 2010 Core Data Library For quite some time, I've been thinking about ways to improve the use of UITableViewController. I experimented a bit with a property-list driven model, and then simplified that into the paired-array version that is in More iPhone 3 Development. One of the things on my "would like to do list" has been to revisit that and create a good, robust tool to make ta
NSFetchedResultsController - Delegate methods crashing under iPhone OS 3.0, but NOT UNDER 3.1
Hey guys, so I've got my NSFetchedResultsController working fine under the 3.1 SDK, however I start getting some weird errors, specifically in the delegate methods when I try it under 3.0. I've determined that this is related to the NSFetchedResultsControllerDelegate methods. This is what I have set up. The inEditingMode stuff has to do with the way I've implemented adding another static section t
How to sort Core Data fetched properties
You can actually grab the model fetched property and add the sort descriptors to it (again, in code). I did this in the standard method that XCode generates in your AppDelegate if you choose one of the templates with Core Data: By the way. This sorts ALL fetched properties on ALL models in your data model. You could get fancy and adaptive with it, but it was the most succinct way to handle sorting
