问题
I trying the full version of apportable and I have a problem with the CoreData:
I have the correct features at configuration.json:
"FEATURES": ["opengles2","landscape","prefer_external_storage","write_external_storage","write_settings"],
Setting the storageURL where I want to store the DB:
#ifdef ANDROID //tried many different locations but not luck, I think there is the problem NSURL *storeURL = [NSURL URLWithString:@"/data/data/com.bluepiggames.zombieSlice/files/Documents/ZS_SuperDatabase.db"]; #else NSURL *storeURL = [[self applicationDocumentsDirectory] URLByAppendingPathComponent:@"ZS_SuperDatabase"]; #endif
Creating the persistenceCoordinatore:
NSDictionary *options = [NSDictionary dictionaryWithObjectsAndKeys: [NSNumber numberWithBool:YES], NSMigratePersistentStoresAutomaticallyOption, [NSNumber numberWithBool:YES], NSInferMappingModelAutomaticallyOption, nil]; _persistentStoreCoordinator = [[NSPersistentStoreCoordinator alloc] initWithManagedObjectModel: [self managedObjectModel]];
Finally, these is the place where the app crash:
if (![_persistentStoreCoordinator addPersistentStoreWithType:NSSQLiteStoreType configuration:nil URL:storeURL options:options error:&error]) { NSLog(@"Unresolved error %@, %@", error, [error userInfo]); //abort();
And no error prompt in the debugger, only a crash like these.
F/libc (10177): Fatal signal 11 (SIGSEGV) at 0xe1a0d013 (code=1) D/dalvikvm( 7227): GC_CONCURRENT freed 387K, 12% free 6566K/7431K, paused 2ms+2ms D/IabHelper(10177): Querying SKU details.

(EDIT) To solve this crash we must set the before:
NSError *error = nil. //!!!!!
if (![_persistentStoreCoordinator addPersistentStoreWithType:NSSQLiteStoreType configuration:nil URL:storeURL options:options error:&error])
Now the problem is in a different place:
// Returns the managed object model for the application.
// If the model doesn't already exist, it is created from the application's model.
- (NSManagedObjectModel *)managedObjectModel
{
if (_managedObjectModel != nil) {
return _managedObjectModel;
}
NSURL *modelURL = [[NSBundle mainBundle] URLForResource:@"ZSDataModel" withExtension:@"momd"];
NSLog(@"Test managedModel found %@",modelURL);
_managedObjectModel = [[NSManagedObjectModel alloc] initWithContentsOfURL:modelURL];
return _managedObjectModel;
}
And the error is because the DataModel compiled not found. Anybody knows how to put the compiled DataModel "DataModel.momod" inside a apportable project?
Thanks
回答1:
sorry for such a late response, but i didn't want to let the question go unanswered. right now momd files aren't automatically added as assets. unfortunately, there's a manual step you'll need to do every time you update the xcdatamodeld.
- navigate to your simulator's Applications directory (e.g.
~/Library/Application\ Support/iPhone\ Simulator/6.1/Applications/<randomString>/<YourApp>.app/
) - navigate into the momd directory
- run the following in terminal:
plutil -convert xml1 <ModelName>.mom -o <pathNearYourApprojFolder>/<ModelName>.mom
- in your configuration.json in the
add_params
dictionary, then in theassets
array, add the path<pathRelativeToApprojFolder>/<ModelName>.mom
of the file you converted with plutil
