title: Objective C : Adding Action On Array of Buttons
body: <p>i'm a newbie in Objective-C can someone help me out here? I am trying to make a carousel of button but i failed to do it.</p>
  
  <p>What i got it just displaying all the buttons on load and that's it. I can't add action on each button, I mean tagging them.</p>
  
  <p>It's my first to do declare button in this way.
  The buttons are not working.</p>
  
  <p>Here's my code:</p>
  
  <pre><code>- (void)loadView {
  
      [super loadView];
  
      self.view.backgroundColor = [UIColor grayColor];
  
      mainHolder = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"feat.png"]];
      [mainHolder setUserInteractionEnabled:YES];
      [mainHolder setFrame: CGRectMake(0, 0, 1024, 768)];
      [self.view addSubview: mainHolder];
  
      header = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"header.png"]];
      [header setFrame:CGRectMake(0, 0, 1024, 50)];
      [header setUserInteractionEnabled:YES];
      [mainHolder addSubview:header];
  
      // The items to be displayed in the carousel
      items = [NSArray arrayWithObjects:
               [UIImage imageNamed:@"picOne.png"],
               [UIImage imageNamed:@"picTwo.png"],
               [UIImage imageNamed:@"picThree.png"],
               [UIImage imageNamed:@"picFour.png"],
               [UIImage imageNamed:@"picFive.png"],
               [UIImage imageNamed:@"picSix.png"],
               [UIImage imageNamed:@"picSeven.png"],
               [UIImage imageNamed:@"picEight.png"],
               [UIImage imageNamed:@"picNine.png"],
               [UIImage imageNamed:@"picTen.png"],
               [UIImage imageNamed:@"picEleven.png"],
               nil];
  
      // Initialize and configure the carousel
      carousel = [[iCarousel alloc] initWithFrame:self.view.bounds];
      carousel.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
      carousel.type = iCarouselTypeCoverFlow2;
      carousel.dataSource = self;
  
      [self.view addSubview:carousel];
  }
  
  
  #pragma mark -
  #pragma mark iCarousel methods
  
  - (NSUInteger)numberOfItemsInCarousel:(iCarousel *)carousel
  {
      return [items count];
  }
  
  - (UIView *)carousel:(iCarousel *)carousel viewForItemAtIndex:(NSUInteger)index
  {
      UIImage *image = [items objectAtIndex:index];
      imageChoices = [[[UIButton alloc] initWithFrame:CGRectMake(253, 150, 518, 389)] autorelease];
      [imageChoices setBackgroundImage:image forState:UIControlStateNormal];
      [imageChoices setUserInteractionEnabled:YES];
      [imageChoices setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
      imageChoices.titleLabel.font = [imageChoices.titleLabel.font fontWithSize:50];
      [imageChoices addTarget:self action:@selector(buttonTapped:) forControlEvents:UIControlEventTouchUpInside];
      imageChoices.tag=index;
      return imageChoices;
  
  }
  
  - (void)buttonTapped:(UIButton *)sender
  {
      //I don't know how to tag each button here.
      switch(sender.tag){
  
      case 1:{
          NSLog(@"Photo1");
      }
          break;
      case 2:{
          NSLog(@"Photo2");
      }
      case 3:{
          NSLog(@"Photo3");
      }
          break;
      case 4:{
          NSLog(@"Photo4");
      }
          break;
      case 5:{
          NSLog(@"Photo5");
      }
          break;   
  }
  }
