How to delete an item from UICollectionView with indexpath.row

swift 3:

func remove(index: Int) {
    myObjectList.remove(at: index)

    let indexPath = IndexPath(row: index, section: 0)
    collectionView.performBatchUpdates({
        self.collectionView.deleteItems(at: [indexPath])
    }, completion: {
        (finished: Bool) in
        self.collectionView.reloadItems(at: self.collectionView.indexPathsForVisibleItems)
    })
}

Swift 3 solution:

func remove(_ i: Int) {

    myObjectsList.remove(at: i)

    let indexPath = IndexPath(row: i, section: 0)

    self.collectionView.performBatchUpdates({
        self.collectionView.deleteItems(at: [indexPath])
    }) { (finished) in
        self.collectionView.reloadItems(at: self.collectionView.indexPathsForVisibleItems)
    }

}

and example delete call:

self.remove(indexPath.row)

-(void)remove:(int)i {

    [self.collectionObj performBatchUpdates:^{
        [array removeObjectAtIndex:i];
        NSIndexPath *indexPath =[NSIndexPath indexPathForRow:i inSection:0];
        [self.collectionObj deleteItemsAtIndexPaths:[NSArray arrayWithObject:indexPath]];

    } completion:^(BOOL finished) {

    }];
}

Try this. It may work for you.
