iOS - segue from alert view is not being called

I have a segue that I want to be preformed when I push the Manual Entry and Scan Tag buttons on my AlertView. 

@implementation triageViewController
- (IBAction)addNew:(id)sender {

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Add A New Entry"
                                                message:@"Choose a way to add a new entry."
                                               delegate:nil
                                      cancelButtonTitle:@"Cancel"
                                      otherButtonTitles:@"Manual Entry", @"Scan Tag", nil];
  [alert show];
}
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
  if (buttonIndex != alertView.firstOtherButtonIndex) {
    [self performSegueWithIdentifier:@"manual" sender: self];
}
  if (buttonIndex != alertView.cancelButtonIndex) {
    [self performSegueWithIdentifier:@"scan" sender: self];
  }
}

(I realize this would probably make the cancel button preform a segue right now, but i'm more concerned with making it work)

I have the two segues in my storyboard, going from a UITabViewController to two different UIViewControllers. neither of these are being called, so when I tap them. I tried using both push and modal segues, but neither one was working.

I also tried the if/else statement like so: 

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
if (buttonIndex == 0) {
    [self performSegueWithIdentifier:@"manual" sender: self];

}
if (buttonIndex == 1) {
    [self performSegueWithIdentifier:@"scan" sender: self];
}
}

But this is not working either.

Could someone help me figure out what is going wrong? Again in case I was unclear, I want to preform a segue from a UIAlertView pop-up located on a UITabBarController to two separate UIViewControllers. Thanks

It looks like your UIAlertView has a delegate of nil so your function is never being called. Set that to self and then in your view controller's header make sure you're implementing the UIAlertViewDelegate protocol.
