uimanageddocument

问题 I would like to create a NSPersistentDocument in Mac OS X and read this document as a UIManagedDocument on iOS 7. Is this possible? Are both file formats compatible? Thank you! 回答1: Interesting question - I can confirm that the basic core data files are compatible. I have a Mac app and an iOS app using the same file that gets synced using iCloud. The app is a document based app and currently I have been storing the actual database file in iCloud so the whole file gets sync'ed by iCloud. This

问题 I'd like to thank all the people that contribute to this website. I am one h*ll of a noob at programming and you all help me out so much. With that said, let's get on with my latest problem! I am creating an app that uses a UIManagedDocument to store a Core Data model for me. I use to create the UIManagedDocument with the following code, but now with Xcode 4.3.2 (The one that updates with the Mac App Store) I have an issue. Here's the code: NSURL *url = [[[NSFileManager defaultManager]

问题 I'm building a tab bar application for iPhone and i'm using Core Data with two UIManagedDocument s. In the first tab, i write the data to database and in the second i read them into UITableView with UIFetchedResultsController . At the start of application, if i write data first, and after then i read results, it works fine. Results appear in the second tab immediately. However, if i read some data first and after then if i write something to database, results appear in second tab with

问题 I have a dictionary created from the DictionaryCreator from UIMA, I would like to annotate a piece of text using the DictionaryAnnotator and the aforementioned dictionary, I could not figure out how to get the annotated text. Please let me know if you do. Any help is appreciated. The code, the dictionary-file and the descriptor is mentioned below, P.S. I'm new to Apache UIMA. XMLInputSource xml_in = new XMLInputSource("DictionaryAnnotatorDescriptor.xml"); ResourceSpecifier specifier =

问题 I am working on my first "iCloud App". I worked through the Apple docs and the Stanford videos but I am still struggling to understand the "Big picture" of iCloud. My goal is to create a "Library style" app (which is Apples term for an app with "a single Core Data stack with a single persistent store coordinator and a single persistent store") like the Employees example. Following the Stanford videos I am using a UIMangedDocument to setup all Core Data stuff and enable the iCloud capabilities

问题 I'm starting to try and add support for state preservation and restoration to my iOS app, which has a Core Data component to it that I access via a UIManagedDocument. I'm starting to add the restoration identifiers to my view controllers, and have hooked up the required functions (currently empty) within my AppDelegate, and controllers. I have an object that could potentially be referenced by multiple view controllers so I plan to try and preserve and restore this within my AppDelegate and

问题 I added a lastModifiedDate attribute to all my entities to avoid duplicates when syncing the UIManagedDocument with iCloud, something that I found it can happen if I create new entities with an offline device (iPad) and, at the same time, I create the same entities using another online device (iPhone). I wanted to set this attribute whenever an object changes so I subscribed for NSManagedObjectContextObjectsDidChangeNotification . The code I wrote to set the lastModifiedDate creates an

问题 I am running into a weird problem. I am sure that I did something to a file somewhere else in my code and it didn't close properly or something, but now it is in a state where it reports as being closed, but when I call OpenWithCompletionHandler it never returns. See below: //if the file is closed, open it and then set up the controller if (file.documentState == UIDocumentStateClosed){ //---- this code executes [file openWithCompletionHandler:^(BOOL success){ // ---- this code NEVER executes
