iCarousel stop at user picked index

Question

EDIT : I'm making an app like a Slot Machine, i added `iCarousel` for the slot object. So I have a button that rotates the `iCarousel`. In my iCarousel view there are two slots (Slot1 and Slot2). Below is my `iCarouselView`: (The box is where the TWO `carousel` is) This is how I spin my `iCarousel`: ``` -(IBAction) spin { [carousel1 scrollByNumberOfItems:-35 duration:10.7550f]; [carousel2 scrollByNumberOfItems:-35 duration:10.7550f]; } ``` Here is what I wanna do: I want to forcefully make it stop to the index the user picks. I have done it this way, the image below is a `newViewcontroller` that contains the `UIImageView` with a button in it, so when the user taps it, my `CustomPicker` pops up. My `CustomPicker` contains the image on what the user have picked on the camera roll. So each button has a specific value sent to my `iCarouselView`. carousel1 for slot1 and carousel2 for slot2. So my problem is to spin the carousel and then for a specific time make it stop to the desired image…

Accepted Answer

It's easy. I've done something similar before.

In the following method below:

```
- (UIView *)carousel:(iCarousel *)carousel viewForItemAtIndex:(NSUInteger)index             reusingView:(UIView *)view{

//Configure your view here
   .....

//Add a button on each view of the carousel
  UIButton * someButton = [[UIButton alloc] initWithFrame:view.bounds];
     [someButton setAlpha:0.0];
     [someButton addTarget:self action:@selector(fingerLanded:) forControlEvents:UIControlEventTouchDown];
     [view addSubview:someButton];
     [view bringSubviewToFront:someButton];

//Add a tag - correspond it to the index
     someButton.tag = index;

//Make sure the view is user interaction enabled
   [view setUserInteractionEnabled:YES];

//Also make sure the button can actually receive touches and there is no view 
    //blocking touch events from being sent to the button.

return view;
}
```

Also add

```
- (void) fingerLanded:(id) sender{

UIButton * theButtonFingerLandedOn = (UIButton *) sender;

//This is the index the user tapped his finger on
NSUInteger index = theButtonFingerLandedOn.tag;

//Scroll to that particular index
[self.carousel scrollToItemAtIndex:index animated:YES];
```

}

Also add

```
- (void) viewDidLoad{

//You may need this to enable user interaction on a view flying by    
  // Look in the - (void)transformItemViews method of the iCarousel library
  self.carousel.centerItemWhenSelected = NO;

}
```

You have to do something similar. Hope it was helpful :) !!
