According to the doco, the above method is used to "customise creation of the
persistent store" especially with regards to the store type. So I've been using
the below code, which works perfectly fine for NSBinaryStoreType and
NSXMLStoreType, but with NSSQLiteStoreType I get lots of merge errors when
saving documents that I don't get if I completely remove the below code and let
the framework handle it. Apparently I'm doing something subtlety wrong. Does
anyone know what? At times like this I wish Apple would make their source code
visible to developers.
- (BOOL)configurePersistentStoreCoordinatorForURL:(NSURL *)url ofType:(NSString
*)fileType modelConfiguration:(NSString *)configuration
storeOptions:(NSDictionary *)storeOptions error:(NSError **)error; {
if(![[[selfmanagedObjectContext] persistentStoreCoordinator]
addPersistentStoreWithType:NSSQLiteStoreTypeconfiguration:nilURL:url
options:[NSDictionarydictionaryWithObjectsAndKeys:[NSNumbernumberWithBool:YES],
NSMigratePersistentStoresAutomaticallyOption, [NSNumbernumberWithBool:YES],
NSInferMappingModelAutomaticallyOption, nil] error:error]){
[[NSApplicationsharedApplication] presentError:*error];
returnNO;
} else {
returnYES;
}
}
