A IGGridViewDataSourceHelper that treats each row as column. These columns are then divided by the numberOfColumns property, and split into rows. If a row does not have enough columns left over to be displayed, no cell will be created for that spot.
A IGGridViewColumnIGGridViewImageColumnDefinition that maps to the one property of your data that will be displayed in the IGGridView.
Returns an initialized IGGridViewSingleFieldMultiColumnDataSourceHelper object or nil if the object could not be successfully initialized.
