- (void)meteorClient:(MeteorClient *)client didAddObjectWithId:(NSString *)objectId beforeObjectWithId:(NSString *)objectId collectionName:(NSString *)name fields:(NSDictionary *)fields;

// remove
- (void)meteorClient:(MeteorClient *)client didRemoveObjectWithId:(NSString *)objectId collectionName:(NSString *)name;
