how to get indexPath for cell which is located in the center of UICollectionView

Question

How can i find indexPath for cell in the middle of UICollectionView?

I have horizontal scrolling and only one big cell is visible (partially two other cells on the sides are visible as well). I need to delete cell located in the center (means - current cell) without touching it.

Only pressing "Trash" button and confirm Delete. But now it delete only first cells.

- (void)actionSheet:(UIActionSheet *)actionSheet didDismissWithButtonIndex:(NSInteger)buttonIndex {
    if (buttonIndex == actionSheet.destructiveButtonIndex) { 
        initialPinchPoint = ????????

        self.tappedCellPath = [self.collectionView indexPathForItemAtPoint:initialPinchPoint];

        Technique *technique = [arrayOfTechnique objectAtIndex:self.tappedCellPath.row];

        [self deleteData:[NSString stringWithFormat:@"DELETE FROM TECHNIQUES WHERE TECHNIQUENAME IS '%s'",[technique.techniquename UTF8String]]];

        [arrayOfTechnique removeObjectAtIndex:self.tappedCellPath.row];

        //[arrayOfTechnique removeObjectAtIndex:[custom_layout ]];
        [self removeImage:technique.techniquename];

        [self.collectionView performBatchUpdates:^{
            [self.collectionView deleteItemsAtIndexPaths:[NSArrayarrayWithObject:self.tappedCellPath]];
         } completion:nil];

         [self checkArrayCount];
    }
}

Like you did yourself, indexPathForItemAtPoint is a good way of finding the index path of the element you're interested in. If your question is: how do i know the coordinates of this point? Then you should try with (using the same name you gave it in your code snippet):

initialPinchPoint = CGPointMake(self.collectionView.center.x + self.collectionView.contentOffset.x, 
                                self.collectionView.center.y + self.collectionView.contentOffset.y);
