推荐答案

做什么@Adrian Pirvulescu说但在显示警告之前做 alert.tag = 1; 然后当 - （void）alertView：（UIAlertView *）alertView didDismissWithButtonIndex：（NSInteger）buttonIndex 被调用do：

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 }
