UIGridView scrollToCellAtCellPath doesn't scroll if column index is less than 2
posted

UIGridView's scrollToCellAtCellPath method doesn't move the very first cell to the center of the UIGridView, I mean it doesn't scroll. But if the IGCellPath's columnIndex property is greater than 2 it works perfectly. Is it a bug or any solution and/or code sample?

-(void)didDeselectRowAtIndexPath:(UITapGestureRecognizer*)gesture {

    //  this method hits when the user taps on any carousel cell. let's say the cell.tag is 0 scroll doesn't work, but if it is greater than 2 it works; it scrolls the cell to the center of UIGridView.

    CarouselCell* cell = (CarouselCell*)gesture.view;
    IGCellPath* toPath =  [IGCellPath pathForRow:0 inSection:0 inColumn:cell.tag];
    [_gridView scrollToCellAtCellPath:toPath atScrollPosition:IGGridViewScrollPositionMiddle animated:YES];

}

    I changed the didDeselectRowAtIndexPath as:

    -(void)didDeselectRowAtIndexPath:(UITapGestureRecognizer*)gesture
    {
       CarouselCell* cell = (CarouselCell*)gesture.view;    
       IGGridViewScrollPosition position;

       if (cell.tag < 2)
       {
           position = IGGridViewScrollPositionMiddleLeft;
       }
       else
       {  
           position = IGGridViewScrollPositionMiddle;
       }

        IGCellPath* toPath = [IGCellPath pathForRow:0 inSection:0 inColumn:cell.tag];
        [_gridView scrollToCellAtCellPath:toPath atScrollPosition:position animated:YES];
    }

    Now it scrolls all the cells from the beginning. Thanks.
