iphone - Pre-filling .sqlite file to add to iOS app, then nothing in .sqlite file but the schema (no data) -


I want to fill in a core data database for use in my iOS app. I am full of databases and I have shown in my app I can see the data I have seen. When I can not fill AppDelegate.m in the database, I do not get anything when I ask the database, when I fill it, then I get the data that I want. So I think there is data in the database. I think that my iPhone Simulator-> MyApp-> is a full .sqlite file in the document. I drag it to my desktop, and I'm using Firefox's skylit viewer tool so that I can check the data in SSKlight file. When I do this, I do not see any lines of data except the schema, metadata, and primary key.

When I use the Firefox viewer to look for other .sqlite files, I see actual data, but this is one I do not see it.

Am I removing data before viewing it in Firefox Tools?

I am adding data like this: 

  NSMOSubClass * tempItem = [NSEntityDescription insertNewObjectForEntityForName: @ Managed object contexts in "EntityName": context]; TempItem.type = typeF; TempItem.internalValue = @ (dataUnit.value); TempItem.name = @ (dataUnit.name); [Self-save reference: context];

I am saving the context like this: 

  - (BOOL) saveContext: (NSManagedObjectContext *) Reference {NSError * error; If (! [Avoid context: & amp; error]) {NSLOG (@ "could not save:% @", [error localized description]); no return; } Yes return; }

I ask for data like this: 

  AppDelegate * appDel = [[UIApplication shared application] representative]; NSManagedObjectContext * Reference = [Apdel Managed ObjectCorrect]; NSError * error; NSFetchRequest * fetchRequest = [[NSFetchRequest alloc] init]; NSEntityDescription * entity = [NSEntityDescription EntityForName: @ Managed object contexts in "EntityName": context]; [FetchRequest Set Entity: Entity]; NSArray * fetchedObjects = [reference executeFetchRequest: fetchRequest error: & amp; Error];
  • I did not make any changes made by Xcode when you started an app with the coredata.

    • The context was not being saved. I have added the following change: 

      If there is an option to (<_ _ _ _ _ _ _ _ _) "" "" ""  @ {NSSQLitePragmasOption: @ {@ " Journal_mode ": @" DELETE "}}  instead of  zero . 
     >  if (! [_stistentStoreCoordinator AddPersistentStoreWithType: NSSQLiteStoreType Configuration: Zero URL: storeURL Option: @ {NSSQLitePragmasOption: @ {@ "journal_mode": @ "DELETE"}} Error: & amp; Error] )

ios - How do I use CFArrayRef in Swift? -

I am using Objective-class in my Swift Project through a bridging header. The method signature looks like this: - Some cement (some type) some parameters; I started by getting an example of class, calling method, and storing the value: var myInstance = MyClassWithThatMethod (); Var cfArr = myInstance.someMethod (some value); Then try to get the value in the array: var valueInArrayThatIWant = CFArrayGetValueAtIndex (cfArr, 0); However, I get the error unmanaged & lt; Cfarray & gt; Not like 'CFArray' . Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
