Question

I there any specific list for animationID in + (void)beginAnimations:(NSString *)animationID context:(void *)context method ?
for example I see this code :

[UIView beginAnimations : @"Display notif" context:nil]; 
[UIView setAnimationDuration:1];
[UIView setAnimationBeginsFromCurrentState:FALSE];

    CGRect frame = paperCurl.frame;
    frame.size.height -= 40;
    frame.origin.y += 40;
    paperCurl.frame = frame;

[UIView commitAnimations];
