uialertview don't do action

I have to put an alert view with the two buttons, but the buttons don't open the urls. I don't know the error. Help please.

Here's the code:

-(IBAction)showAlertView {
UIAlertView *alert = [[UIAlertView alloc]
                      initWithTitle:@"Obrir en..."
                      message:@"Es pot requirir la aplicació de Google Maps"
                      delegate:self
                      cancelButtonTitle:@"Millor no..."
                      otherButtonTitles:@"Mapes",@"Google Maps",nil];
[alert show];
}
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
NSString *title = [alertView buttonTitleAtIndex:buttonIndex];

if([title isEqualToString:@"Mapes"])
{
    UIApplication *ourApplication = [UIApplication sharedApplication];
    NSString *ourPath = @"http://maps.apple.com/?q=Plaça+del+Rei+43003+Tarragona";
    NSURL *ourURL = [NSURL URLWithString:ourPath];
    [ourApplication openURL:ourURL];

}
if([title isEqualToString:@"Google Maps"])
{
    UIApplication *ourApplication = [UIApplication sharedApplication];
    NSString *ourPath = @"comgooglemaps://?daddr=Plaça+del+Rei+43003+Tarragona&directionsmode=walking";
    NSURL *ourURL = [NSURL URLWithString:ourPath];
    [ourApplication openURL:ourURL];
}
    }

NSString *enc = [match.location stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

NSString *location = [NSString stringWithFormat:@"%@%@", @"http://maps.google.com/maps?q=",enc];
NSLog(@"%@", location);
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:location]];

You have to do url encoding for your urlString because it contain some special character. 

NSString *ourPath = @"http://maps.apple.com/?q=Plaça+del+Rei+43003+Tarragona";
ourPath=[ourPath stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

I thing your send URL is wrong

it should be 

maps.google.com//?daddr=Plaça+del+Rei+43003+Tarragona&directionsmode=walking

instead

comgooglemaps://?daddr=Plaça+del+Rei+43003+Tarragona&directionsmode=walking

clickedButtonAtIndex...

It is delegate method of UIAlertView, This method is use for fire action related to selected button of UIAlertView

for example :

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
  if(buttonIndex == 1)
  {
      /// write code for button 1 of UIAlertView; (here put 1 URL)
  }
  else if(buttonIndex == 2)
  {
    /// write code for button 2 of UIAlertView; (here put 2 URL)
  }
}

So, why you use two UIAlertView for TWO URL, put url in separated block of button clicked in delegate method of UIAlertView.
