Question

So I see there is an init method in RestKit’s reference: objectStoreWithStoreFilename:inDirectory:usingSeedDatabaseName:managedObjectModel:delegate which suppose to initialize objectStore in specified Directory. “inDirectory” parameter accepts NSString. I’ve tried @”Library/Caches” and [self.applicationCachesDirectory absoluteURL] where self.applicationCachesDirectory returns URL of the Caches directory but I’m getting exceptions.

Please tell me how can I specify “Library/Caches” in this method in order to save sqlite DB in the Caches directory instead of Documents?

Got it working. I’ve created helper method to get Caches folder path as NSString

    - (NSString *)applicationCachesDirectoryString
{
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES);
    NSString *cachePath = [paths objectAtIndex:0];
    BOOL isDir = NO;
    NSError *error;
    if (! [[NSFileManager defaultManager] fileExistsAtPath:cachePath isDirectory:&isDir] && isDir == NO) {
        [[NSFileManager defaultManager] createDirectoryAtPath:cachePath withIntermediateDirectories:NO attributes:nil error:&error];
    }
    return cachePath;
}

and then passed it to the objectStore init method:

self.objectManager.objectStore = [RKManagedObjectStore objectStoreWithStoreFilename:databaseName inDirectory:[self applicationCachesDirectoryString] usingSeedDatabaseName:seedDatabaseName managedObjectModel:managedObjectModel delegate:self];
