delete from the array? and what do you mean by delete the image from its original position. – Bazinga
- (BOOL)carouselShouldWrap:(iCarousel *)carousel { return NO; } I am already using this in my code – Youngwing
IT should delete when it is in its current position..But with my code it is scrolled to caroselframe position. – Youngwing
Simply I able to edit or delete the image which is in firstposition of my visible screen – Youngwing

You shouldn't delete the item at the carousel.currentItemIndex because that is not the item corresponding to the button you clicked, that's just the currently centred item in the carousel.

To get the correct item index for the button you clicked, do this:

-(void)deleteButtonClicked:(id)sender
{
    //get the index of the item view containing the button that was clicked
    NSInteger index = [carousel indexOfItemViewOrSubview:sender];

    //update the data model (always do this first)
    [imagesArray removeObjectAtIndex:index];

    //remove item from carousel
    [carousel removeItemAtIndex:index animated:YES];
}

Try this:

    NSInteger index = carousel.currentItemIndex;
    [carousel removeItemAtIndex:index animated:YES];
    [imagesArray removeObjectAtIndex:index];

add this also:

- (void)awakeFromNib
{    
    if (self) {
        //set up carousel data
         wrap = NO;
    }
}

or make your

carousel.type = iCarouselTypeCustom;

to

carousel.type = iCarouselTypeLinear;

then implement this: [carousel reloadData];
