Do what @Adrian Pirvulescu said but before showing the alert do alert.tag = 1; and then when - (void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex is called do:

if (alertView.tag == 1) {
    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"2nd Alert" 
    message:@"My message" delegate:self cancelButtonTitle:@"Cancel"
    otherButtonTitles:@"OK", nil];
    alert.tag = 2;
    [alert show];
    [alert release];
}
else if (alertView.tag == 2) {
    [self CallSomeMethod];
}
else {
    //do what ever you want here
}
