Obj-C classes start with a capital letter, by convention. So -- Root, Song, Artist, and Modification would be standard.
-(void)dataBaseHaveChange:(NSNotification*)notification //I
receive here the notification of a CoreData modification

NSNotification* userInfo = [[notification
userInfo] retain];
No need to -retain the userInfo.
NSSet* objectsSet = nil;
objectsSet = [userInfo valueForKey:NSInsertedObjectsKey];
You want -objectForKey: -valueForKey: is for key value coding, - objectForKey: is for extracting objects from a dictionary.
Shouldn't cause a problem.
for (NSManagedObject* modEntry in objectsSet) {
Are you sure objectsSet contains any objects?
if ([modEntry isKindOfClass:[root class]]) {
//do something
}
}
